Does anyone else feel vaguely guilty for not reusing something you know you could but don’t because you just don’t have the energy to follow through? I recall watching an infuriatingly organized Instagrammer showing me how she simply scattered used coffee grounds in her garden and, voilà – bumper crop! My routine? Tossing leftover coffee detritus in the trash and harvesting dead bugs from my wilted zucchini vine. (It should be noted that, on my more optimistic days, when I find myself wandering aisles of healthy plants at a nursery wondering what could be, I can actually hear them shrieking in fear lest I bring one home and seal its fate, coffee grounds notwithstanding). I try. I really do. Most of us want to do more, do better, improve on our efforts to match the ingenuity of our wartime ancestors who could figure out a way to reuse a soggy match. I choose to blame my shortcomings on progress and convenience. Hats off, therefore, to the forward-thinking Allseas for repurposing a traditional tool of the hydrocarbon industry into a boon for offshore wind.

Swiss-based Allseas was founded in 1985 to debut the world’s first Dynamic Positioning pipe laying vessel, the Lorelay1. The company would go on to build many more pipelayers to help service the offshore oil market mining the North Sea and other oil-rich venues. In an effort to expand into installing the structures serviced by those pipelines (and seeing equal value in their decommissioning, “the process of ending operations at an offshore oil and gas platform”2) Allseas engineers drew up plans for a gargantuan vessel that would be up to the task. Twenty years later, the company finally announced their intent to build it. Despite the notable delay (due to the usual suspects: economy, supply chain, various unsavory world events, etc.), Daewoo Shipbuilding & Marine Engineering won the contract in 2009 and got to work. By the time the final product debuted in February of 2015, the Pioneering Spirit became the largest Offshore Construction Vessel in the world3

Today, the Pioneering Spirit has several record-breaking lifts under her belt, including the recent removal of “the last platform of the Shell Brent field in the North Sea… with topsides weighing 31,000 t.” Additionally, her dynamic positioning and catamaran design

give her a big advantage in rougher seas, and her rating for light ice allows her access to polar regions. But the coolest thing, in my opinion, is her jacket lift system. “A jacket is a steel support structure that rests on the ocean's floor and has columns or legs extending from below the seafloor up through the sea surface.” Recycling the jacket usually requires explosives and/ or dismantling by deep sea divers. Until the Pioneering Spirit, that is; watching the ship in action as it lifts up the topside rig is one thing –seeing it extract a full metal jacket from under the waves in one piece is a sight to behold.

With her sheer mass and heavy lifting capabilities, the Pioneering Spirit is a gift to the growing offshore wind industry. As wind components continue to grow in size, and shoreside assembly proves a more cost-effective option than building on site, this vessel’s ability to move a near-complete construction to deep water can save money, time, and lives.

Allseas projects now include several offshore wind installations around the world, and I expect to see more wind companies availing themselves of this mega ship in the near future. Randomly clicking through their website, I was also pleasantly surprised to learn of their recent forays into clearing rivers of plastic pollution. Rig recovery, offshore wind, and preserving our waterways – this veritable trifecta of opportunities may have been a long time coming, but I’m glad it’s finally here.

Conducting Tomorrow’s Electricity through an Aging Grid

Largely unchanged for decades, the U.S. electricity grid faces immense pressure to support the growing demand for renewable energy sources, electric vehicles, and a rising population. Much of the grid infrastructure is reminiscent of the days when today’s senior citizens were children, with power lines strung up and down streets in a familiar web. Comprised primarily of aluminum conductor steel-reinforced (ASCR) cables, this legacy product – while rooted in the past – still offers value, and can serve as a foundation for future enhancements. The Department of Energy estimates that the nation’s network of transmission lines needs to expand by 4 times or more by 2035 to meet clean energy goals.

Upgrading existing infrastructure with advanced conductors is a critical and efficient solution. Doing so can double the grid's capacity and integrate much more wind and solar power, all while overcoming regulatory and bureaucratic hurdles.

Pressing need for capacity

The grid's growing demand is no secret. The current infrastructure is under immense pressure to support an increasing load. As more renewable energy sources come online and the adoption of electric vehicles rises, the need for a more robust and efficient grid becomes ever more critical. One of the biggest obstacles to expanding clean energy is the lack of power lines. Building new transmission lines, however, can take a decade or more due to permitting delays and local opposition.

How do advanced conductors help?

Advanced conductors are designed to address the critical capacity concerns facing the U.S. electricity grid. According to the Idaho National Laboratory Advanced Conductor Scan Report (December 2023), these conductors can have a significant impact on grid performance.

For example, the ACSS/TW/MA5/E3X conductor, when used in the same footprint as a traditional ACSR conductor, can provide a remarkable 218 percent increase in capacity. It also offers the following advantages:

• Enhanced strength and durability: Steel cores in these advanced conductors improve breaking strength by 2-3 times compared to traditional current aluminum conductors, providing better resistance to thermal sag and heavy load conditions like wind and ice.

• Efficiency improvements: These conductors significantly reduce line losses. The Idaho National Laboratory report highlights that advanced conductors like the ACSS/TW/MA5/E3X reduce resistance at 20°C by up to 20 percent, and at maximum operating temperatures (MOT) by up to 21 percent compared to ACSR conductors. We need this efficiency as more renewable energy sources are integrated into the grid.

• Longevity and safety: Specialized zinc-based coatings offer superior corrosion resistance to ensure the conductors remain functional and safe, even in harsh environmental conditions like coastal or industrial areas. This durability reduces the need for frequent replacements and maintenance, providing long-term cost savings and reliability.

Real-world applications

The Bonneville Power Administration (BPA) is upgrading its grid with ACSS/TW Plover conductors, which are compatible with existing towers. These new conductors operate at higher temperatures, and significantly increase capacity. While current ACSR conductors run at 2,300 amps, the ACSS/TW Plover can handle over 4,300 amps – an

Powering the Future

How data center growth and offtake capacity drive renewable energy innovation

The first data center development was built in 1945, to house the Electronic Numerical Integrator and Computer (ENIAC). The ENIAC was the first electronic digital programmable general-purpose computer; it occupied over 300 square feet of space, and weighed over 27 tons. Although it could only perform numeric calculations, this first data center had huge fans and vents to cool the heat generated from processing. Today’s data centers are quite different. The exponential growth of data center development around the world needed to support the digital transformation, edge computing, and increased demand for cloud services, is astounding.

Nearly half of the estimated 11,000+ data centers worldwide1 are in the United States alone. For perspective, the International Data Corporation determined that 1.2 zettabytes of new data had been created globally in 2010 (1 zettabyte = 1 trillion gigabytes). In 2025, that data creation jumps to 175 zettabytes2. Just between 2018 and 2020, more data was created than in all human history before 20183

For the renewable energy industry, data center development presents a goldmine of opportunity, and is an increasingly sought after area for renewable energy developers. In addition to the global energy demand, data centers consume large amounts of electricity, requiring reliable and stable power. Many of the tech companies operating data centers have also set ambitious sustainability targets. On the other side of power generation, governments and local authorities offer incentives for renewable energy development, making these partnerships mutually beneficial.

As with any other renewable energy development, land suitability plays a critical role in the development of new data centers. Access to suitable land with robust infrastructure, reliable power supply, and favorable economic conditions is essential for their successful operation. Virginia, often referred to as the "Data Center Alley," has emerged as a major hub for data centers in the United States. In

addition to numerous data centers, Virginia hosts colocation, hyperscale, and edge facilities. It is home to over 150 hyperscale data centers, representing 35 percent of all known hyperscale data centers worldwide. The current offtake capacity (the amount of power that data centers can draw from the grid to meet their operational needs) is substantial, particularly in Northern Virginia, where the robust infrastructure, reliable power supply, and favorable economic conditions are designed to support the high energy demands of numerous data centers. However, this rapid expansion has led to significant energy demands that challenge the available offtake capacity. Data centers in Northern Virginia already consume over 1,600 megawatts, with demand expected to double by 20354,5, and contribute to an anticipated 12 percent annual increase in peak electric load over the next 15 years6. Because the data center industry significantly boosts Virginia’s economy (generating $1.2 billion in tax revenue annually, including $1 billion for local municipalities and $174 million for the state7), state legislators have developed attractive incentives. The Virginia Economic Development Partnership (VEDP) offers a 6 percent Virginia retail sales and use tax exemption on IT equipment and enabling software. The upcoming Mega Data Center Incentive Program proposes extending these exemptions for up to 15 years on qualifying equipment; this program currently runs through 2035, and includes up to $140 million for site and infrastructure improvements, workforce development, and other projectrelated costs. Virginia’s Henrico County will allocate $60 million from data center revenues to its first Affordable Housing Trust Fund8, which aims to support housing affordability through grants to nonprofit and for-profit entities. The initiative follows the approval of a new data center campus by the Henrico County Board of Supervisors, reflecting Henrico’s effort to balance technological growth with community benefits, and addressing concerns about affordable housing and environmental impact.

There is also a growing emphasis on energy efficiency and sustainability, with data centers implementing measures to reduce their carbon footprint and increase the use of renewable energy sources like solar. Security and compliance with state and federal regulations remain paramount, ensuring that data centers maintain high standards of data protection and operational integrity.

Despite advancements, challenges related to infrastructure and connectivity need to be addressed. Ensuring a reliable power supply, effective cooling systems, and robust network connectivity are critical for the smooth operation of data centers. Projections indicate that the electricity demand for all of Virginia's data centers could reach 13.3 gigawatts by 2038, necessitating significant infrastructure upgrades and raising concerns about environmental sustainability9. The regulatory environment also plays a significant role in shaping the development and management of data centers; the state’s commitment to reducing carbon emissions and promoting renewable energy sources is critical in addressing the environmental impact of the growing industry. However, ample growth opportunities exist, with potential for further expansion of data centers and enhancement of offtake capacity to meet future demands.

The trends and activities of data centers highlight their critical role in the digital economy and their significant economic impact, and are setting an example the rest of the world will undoubtedly follow. Accurate and efficient management of offtake capacity is essential for ensuring reliable operations and supporting future growth. In order to maintain a sustainable future for energy infrastructure, it is imperative for the energy industry to prioritize data accuracy and technological innovation.

Solar Inverter Training

Ensuring efficient troubleshooting and safe operation

Solar inverters are critical components for photovoltaic (PV) systems. They are responsible for converting direct current (DC) generated by solar modules into usable alternating current (AC) for homes and businesses. However, like any electronic device, solar inverters can experience faults or issues that may affect overall system performance; these faults and issues need to be addressed in a timely manner. Some inverters are designed to be “popped and swapped”, meaning ripped out and replaced with a new one. Others have been designed to be field repairable, which can significantly reduce downtime to have the inverter up and running within 30 minutes. However, since each inverter is different, doing so requires proper training on how to safely approach a faulted inverter, troubleshoot it, and fix it. In this article, we’ll uncover the elements of proper training, and how it can drastically increase efficiency when addressing common solar inverter problems.

1. Safely approaching a solar inverter for servicing

Whether an inverter needs to be serviced for preventative maintenance or to address an issue, it’s always important to understand what faults a system could encounter. Inverter “A” may not have the same safety considerations as Inverter “B”, so understanding which ground fault detection method is being used can give you context about what to look out for. In other words, different ground fault detection methodologies could present dangerous conditions differently. Proper inverter training should teach technicians how to safely work on the inverter, and avoid damage to the inverter and/or injury to themselves.

2.

Replacing parts correctly to prevent further damage

Faulty installation and improper replacement could cause further problems with an inverter. Errors in connecting solar panels to the inverter, in DC wiring, AC wiring, or in overall installation, can significantly impact safety and performance. Inverter service training helps prevent the following three things from occurring: Errors or warnings requiring support: Improper repair can cause errors or warnings that affect the performance of the inverter. For example, replacing a board that holds network or communications settings may then require reconfiguration for the inverter to be able to communicate with other devices again. A similar scenario is forgetting to attach a connector back to the hardware it’s sensing, so now it’s reading no data and thus produces warnings. It can be time consuming and costly to call technical support and wait for them to get back to you with instructions on how to troubleshoot and resolve the issue. This can be avoided with technicians who are trained on how to properly service the inverter and any necessary configurations. Damage to the inverter: Beyond warnings or faults, improper repair can also cause damage to the inverter that may not be covered under warranty. For example, loose connections from not properly torquing down busbars or any conducting material in the power path can cause high resistance, which produces heat and causes major damage. Another example is improperly seating boards with each other, causing bent pins. Training can and should walk through common scenarios like these, and provide clear guidance for avoiding damage.

Safety hazards: Because inverters handle high voltages, faulty repairs can create safety risks like electrical hazards. In-depth training minimizes risks by providing step-by-step repair instructions.

3. Inverter communications and networks

As many technologies have advanced with the Internet of Things (IoT), so have inverters. This includes inverter communications and how they connect with other devices, such as monitoring systems, control systems, and eventually the internet. The main purpose of inverter communications is to facilitate real-time monitoring, control, and data acquisition of inverter systems, which can be used for improving system performance and site optimization. What this means is that having some understanding of networks and communications has become a more necessary skill in the toolbox. When commissioning or beginning inverter repairs involving components that handle communications, understanding basic networking concepts such as IPs, subnet masks, and subnetworks is valuable for a smoother commissioning process and/or efficient troubleshooting. Having this understanding, as well learning basic Modbus concepts and tools, can also give you more ways to troubleshoot communications issues. For example, if there is an issue with the Data Acquisition System (DAS) to inverter communications, you can troubleshoot this using your laptop to simulate the DAS, send Modbus commands, and isolate whether the issue is with

the inverter configuration, the DAS, or the hardware. For sites that use Modbus TCP/, important concepts to understand are the differences between Network IDs, Host IDs, Ports and Subnet masks, and what their part is in a network. This understanding can make troubleshooting more efficient.

4. Troubleshooting guidance and tips for equipment (Mechanical, Electrical, or Communications)

- Common fault indications and how to respond

Familiarizing yourself with common fault indications displayed by your inverter can give you key clues on the root cause of the issue. These may include error codes, warning lights, or abnormal behavior. The first step in troubleshooting is to find any information on what the error could be. Though the user manual will have specific instructions for addressing each fault, hands-on training is invaluable and can help you familiarize yourself much faster. The best training programs eliminate guess work, diving into what each indicator could mean, and how to test the inverter to find the root cause.

- Mechanical troubleshooting

Some symptoms may appear to be electrical, even though the root cause may actually be mechanical. Inverter training should help you understand all possible root causes for each symptom so you’re not wasting your time looking in the wrong place. For instance, if the inverter is operating at 80 percent power, it could appear to be an electrical or settings issue. It’s also possible that a fan is not working correctly, causing excessive heat and the inverter to de-rate, which can lead to performance degradation or complete inverter failure over time.

- Electrical troubleshooting

Electrical issues normally stem from some mechanical or settings issue. In most cases, the inverter will be the first indicator that an issue has occurred on site, so you will need to determine if it’s actually an inverter issue, or something upstream or downstream. Inverter training teaches you to more quickly interpret inverter event codes and find the true source of the problem. In many cases, it may not be the inverter itself, but a ground fault at the array or some grid events that the inverter is

required to respond to. However, there could also be some more complicated problems to troubleshoot that may require special skills or tools, such as:

• Electrical noise that can disrupt the inverter’s control circuits and other sensitive electronics that affect efficiency and reliability.

that offers thorough training that will enable your team to be as safe as possible while minimizing downtime. Remember that safety always comes first. If you encounter issues beyond your expertise, consult a professional solar technician or installer with that specialty.

Onshoring Solar Production and Supply Chains

‘Reshoring’ became the buzz word in 2012, when companies began rethinking real manufacturing costs. The term was embraced by companies and government alike as they sought to reverse the offshoring trend from the 90’s that proved harmful, particularly to the Industrial Midwest, and to U.S. competitiveness as whole.

Recently, we entered a new era – the ‘onshoring’ era – in which companies and policymakers are working together to bring new technology and advanced manufacturing to the US for the first time. A great example is what’s happening in the U.S. solar market.

In standing up new, American-based manufacturing facilities, American companies are enabling the United States to reverse-transfer solar manufacturing capability and technical know-how that it ceded long ago to China.

Onshoring the complete solar supply chain will of course take time, which is why companies are partnering with leading global solar panel manufacturers. For next-generation U.S. solar manufacturers to catch up to China, they must be able to license best-in-class technology and learn from it. This is only possible when American companies can work with firms

that have the technical knowledge and capabilities to manufacture most of the solar supply chain.

The first facilities in the solar supply chain that can be reshored are panel manufacturers. The next upstream step in the manufacturing process, like solar cells, will take more time. That means domestic panel manufacturers will need to import cells until adequate domestic capacity can be built and available.

There’s tremendous momentum behind onshoring and establishing American solar leadership, but success is not guaranteed. There are some who want to make it harder for the U.S. to build out its own supply chain by prematurely cutting off global suppliers – via tariffs – before a domestic supply chain exists. Doing so would be a mistake because it would slow down job creation, stifle solar energy deployment, discourage innovation, drive up costs, and ensure that America’s solar industry will continue to lag behind China’s technologically.

Perhaps most importantly, cutting off global suppliers before a domestic supply chain exists would impact American workers and our economy. That’s because competition within the solar manufacturing industry means more quality local jobs, higher wages, and better benefits. New data by the American Council on Renewable Energy found that newly proposed tariffs on solar cells (none of which are made in the USA, by the way) would threaten roughly 9,000 U.S. module factory jobs.

Even more advanced manufacturing careers are coming with microchip manufacturers and auto industry advancements. Solar is leading the charge to upskill local workforces while onshoring parts of the supply chain. A domestic supply chain will benefit not only solar manufacturing, but numerous other industries and communities that are eager to contribute to the resurgence in American innovation.

We’ve made remarkable progress in just a few short years, and we need to get this right because the stakes are high. Demand for low-cost, secure, and lower carbon power is only increasing. We need more domestic clean energy investments, not less, if we’re going to reach our clean energy and climate goals.

“Made in the USA” is every domestic manufacturer’s goal, but doesn’t happen overnight. Our government

should be encouraging companies to bring solar expertise and supply chain back to America, not putting up roadblocks to protect companies that have had decades to accomplish what new entrants must scramble to achieve. I hope to look back on this time as the start of a golden age in clean energy advancement and innovation as we bolster both small town and national economies, and accelerate the delivery of cleaner, more reliable, affordable energy.

Your Comprehensive Guide to Solar Cable Requirements

No matter where you’ve seen them – buildings, agricultural facilities, open spaces, even floating on the surface of water – all photovoltaic systems use special solar cables to interconnect the individual modules with each other, as well as with the inverter and other components.

Photovoltaic systems consist of a multitude of individual modules that convert solar energy into direct current (DC). In order to make it usable, the individual modules are connected in parallel or in series using cables designed to carry direct current. The same applies to the cable that connects the photovoltaic modules to the inverter. This device converts the generated direct current into grid-compatible alternating current (AC).

How are solar cables structured?

Previously, the requirements for solar cables were defined in the PV1-F standard. Acceptable conductors were identified with the respective abbreviation. Since 2015, the updated standard – EN 50618 – has been in effect. Suitable solar cables are now labeled as "H1Z2Z2-K". This imprint guarantees the cable possesses all the necessary characteristics for use in photovoltaic systems. For the U.S. market, the 2023 edition of the NEC (National Electrical Code) developed Article 690 - Solar Photovoltaic (PV) Systems to provide guidance on electrical energy systems, array circuits, inverters, and charge controllers for PV systems. The NEC is commonly used in the United States for various installations (local codes may still apply). PV cables must also be approved under UL Standard 4703, while c(UL) or CSA 22.2 No. 271 must be obtained for use in Canada.

Solar cables are typically single conductors with a finely stranded, tinned copper wire. For both the conductor insulation and the outer jacket, specialized polymers have proven to be effective, as they offer superior properties compared to rubber or PVC, particularly in terms of durability. Depending on the plastic composition, the cables are suitable for various applications, including outdoor use and underground installation. The cross section of a solar cable should typically be a minimum of AWG12 (4 mm²). The cables are available with cross sections of up to 500 kcmil (240

mm²). It is crucial to select appropriate cross sections for optimal power generation carefully.

What requirements must solar cables meet?

Depending on where they are deployed in the field, photovoltaic systems are exposed to high and low temperatures, various weather conditions, humidity, chemicals, and (of course) solar radiation. Despite these challenging environmental conditions, they must function reliably for extended periods as manufacturers and operators plan for a system lifespan of 20 to 30 years. Accordingly, all installed components must meet high standards –this applies to the wiring as well. According to EN 50618, solar cables should possess the following characteristics:

• Weather, UV, and ozone resistant Wind, weather, and the UV radiation of sunlight accelerate the aging of cables. Solar cables must therefore comply with the standards of DIN VDE 0283-618 and DIN EN 50618.

• Temperature resistant When used outdoors, the cables may be exposed to extreme heat or cold. Therefore, solar cables are designed for a temperature range of -40°C to +90°C.

• Flame retardant and halogen-free In the event a photovoltaic system experiences a fire, it is crucial that the cables used are highly flame-resistant and do not emit toxic gases when burning. Solar cables are therefore halogen-free according to DIN VDE 0482-754-1 / DIN EN 607541 / IEC 60754-1 and flame-retardant according to

DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2. Other flame tests that can be passed are VW-1 in the U.S. and FT1 in Canada.

• Dielectric strength

The direct current in photovoltaic systems can exceed 1,000 volts. Solar cables possess an exceptional level of voltage resistance. The test criteria for this are defined in DIN VDE 0283-618 / DIN EN 50618 Table 2. For specialized applications, such as in agriculture, outdoor environments, or on water, solar cables with specific characteristics are available. These characteristics include:

• Mechanical strength

Even though solar cables are rarely moved in the field, they need to be resistant to abrasion and other mechanical stresses for long-term operation.

• Acid and alkali resistant

In the agricultural sector, solar cables may be exposed to ammonia, oxalic acid, caustic soda, or other chemicals. Therefore, the outer jacket must be acid- and alkaliresistant according to EN 60811-2-1.

• Rodent protection

Mice, rats, and other rodents can damage a photovoltaic system’s cables, which can lead to disruptions and outages. To prevent this, solar cables are also available as a special variant with a specific rodent protection feature consisting of a braided stainlesssteel mesh that is placed around the exterior of the cable.

• Floating PV certification For floating photovoltaic systems, also known as floating farms, specific testing regulations apply under TÜV 2 PfG 2750. Therefore, cables used in these installations should be appropriately certified.

Summary

Although solar cables are relatively simple in structure, they must meet high standards to satisfy diverse requirements. Simultaneously, they should ensure the reliable operation of the photovoltaic system for approximately 20 to 30 years. Therefore, it is crucial that the cables used are made of high-quality materials and manufactured properly to comply with all applicable standards and regulations.

Utility-scale solar mounting and racking system design is a delicate balancing act of building for site conditions while ensuring cost effectiveness for the client, maximum energy output for the end user, and healthy returns for investors.

Given North America’s varying landscapes and climate zones, each solar project presents its own unique design challenges. No design is the same, but a holistic approach should always be the main guiding principle.

Focusing on the big picture accounts for complexities, informs a successful design to produce maximum energy output for the communities we serve, and a financial return for investors. Examining data, weather patterns, and geographic challenges, and gathering information from landowners, are all crucial aspects of the design process.

Design decisions impact the entirety of a solar facility’s performance and its longevity. When you consider the entire system cost, capital investment, downtime, repair cost, and Integrated Subsystem-System Performance Analysis (ISSPA), a megawatt hour is cheaper in the long run.

Leveraging the power of data

When it comes to utility-scale solar mounting and racking system design, data is the single source of truth. With the right data, we can understand how various systems perform and drive decision making to execute our projects with precision. Data can make our products better, helping us to provide sound advice to our clients that’s backed by scientific evidence.

Each project requires special consideration. Data offers irrefutable facts that guide billions of calculations, and provides the precision required to ensure the stability, efficiency, and longevity of a solar power installation.

Examining weather trends to shape solar designs

While they’re driven by math and science, engineers are also historians; they predict the future by examining the past. This includes a comprehensive examination of local

weather patterns over the past 25 years (including sun exposure) to maximize the potential of the solar panels. It also includes considerations for:

• Wind

The biggest risk for mounting and racking system design is wind. Fixed tracking systems face the wind regardless of speed. Most single- or dual-axis tracking systems have wind gust sensors, allowing them go into a stowed position to become more aerodynamic.

Fixed racking systems are supposed to deliver about 20 percent less energy than a single- or dual-axis tracker system. If designed right, however, they can produce a lower cost of electricity in some situations, when evaluated in an ISSPA that includes all factors.

• Temperature Cold weather and frost-susceptible soil affect the design’s pile foundation. Ensuring trackers don’t heave requires either helical piles with plates buried below the frost line, or alternative frost-resistant pile designs. In some cases, with trackers spanning the length of a city block, the steel experiences maximum expansion and contraction due to temperature extremes. Attention must be paid to torque tube movement to ensure there’s no mechanical interference that could lead to an overworked drive motor, mechanical binding, and eventual failure. Closely examining historical trends and layering them on top of other drawings ensures that proper care and attention is given to the history and patterns of the land; these are best understood by long-term landowners. Understanding the probability of weather events mitigates risk and optimizes site performance.

Leveraging historical insights and community knowledge

If lessons learned from the past aren’t applied to future designs, history is bound to repeat itself – one piece of data often overlooked during the design process is the perspective of the local community and landowners.

Local conditions at solar sites aren’t always what people from urban centers think they are. Collecting historical narratives about the site from those who live there and have firsthand experience reduces potential blind spots in the raw data. The oral history helps inform robust data for the design, and is something that can be used in discussions with the client to help them fully understand the benefits of proposed design characteristics.

Renewable expansion: balancing solar power and urban growth

As urban centers expand to accommodate growing populations, the demand for power and the diversification of energy supplies increases. It's crucial to position power sources nearby, but not so close that they impede city development.

Flat desert sites are ideal for a utility-scale solar solution, but many are either already in use or too far away from the grid. On the other hand, hilly sites with fluctuating terrain are challenging to build on but, in many cases, exist in an ideal zone.

As we become increasingly dependent on renewable energy, engineering and design play an invaluable role in overcoming geographical challenges and delivering the right solutions to meet the needs of the communities we serve.

Preventing Corrosion on Renewable Energy Projects

Corrosion is an issue that needs to be evaluated on every renewable energy initiative – solar, energy storage, and substation; managing it has become a critical consideration in project engineering and implementation. For example, a key material in photovoltaic arrays foundations and battery energy storage system foundations is steel, which tends to corrode over time, and is affected by the degree of corrosiveness of the soil surrounding it. However, it’s important to have steel piles last throughout the operational life of the projects they support. Therefore, the more corrosive the soil is at the site, the more precautions that need to be taken to protect the steel pile that comes in contact with that soil.

Overcoming the corrosion challenge

The renewable energy industry is running out of good soil and friendly landscapes for utility-scale renewable energy projects. Many prospective sites today have a level of corrosiveness that would have led developers to avoid them in the past. With many of the prime lands for utility-scale solar projects already in use, the growing demand to expand solar generation and other energy resources is leading developers to give less-than-ideal sites a closer look – making soil testing critical to address the corrosion challenge beforehand.

The steps to corrosion analysis and prevention

The process to address and make accommodations for soil corrosion involves a series of steps:

Soil tests provide the data for understanding the extent of the corrosion challenge at a potential utility-scale solar and renewable energy site, and allow for designing appropriate solutions to address it. Corrosion consultants are also brought in to provide steel corrosion reports and assist with project design. In fact, it’s now standard design procedure to have a corrosion report stamped by a corrosion specialist in place before beginning engineering and construction. Corrosion

• Geotechnical engineers conduct field and lab analysis of the soil and test its PH values and electrical resistivity. With this data, and working in conjunction with corrosion engineers, they look at geotechnical results and corrosion rates for bare steel and hot-dipped galvanized steel.

• The structural engineers then design steel foundations and piles to account for the soil corrosion rate, taking into consideration the corrosive steel properties at the end of the project life, when steel piles and foundations become smaller and weaker.

• In addition, if concrete is used for the foundations, which is the case for substations, it is critical to ensure that the concrete mix design is corrosion-resistant (the geotechnical report will spell this out). Concrete is porous, so all the metal bars need to be protected.

• To account for design requirements, as well as the loss of material from corrosion over time, uncoated steel foundations need to be larger to start with. Hot dip galvanization adds protection to resist long-term corrosion.

• In cases of high corrosion rates due to excessive moisture in the soil, caused by a high-water table or location near a body of water and resulting in highly acidic or alkaline conditions, cathodic protection systems or epoxy coating can be utilized.

• Once designs have been created, they go to the authority having jurisdiction who reviews the geotechnical report, the corrosion report, and the structural design. While corrosion is typically associated with metal, the strategies discussed here are also applicable to other materials, including the plastic in junction boxes and the cable insulation and other materials exposed to moisture and harsh elements.

A procedural imperative

As the construction of alternative energy facilities and infrastructure continues to accelerate, it is imperative that owners and facilitators of these projects recognize and make accommodations for the inevitability of corrosion. In summary, here are some of the solutions that have proved effective:

• Additional steel – a larger section of steel pile may be used to account for the loss due to corrosion over time.

• Galvanization – a process that uses zinc as a protective coating over steel or iron. Hot-dip galvanizing has provided steel corrosion protection for over 150 years, and at least half a century for structures used in the generation, transmission, and distribution of energy from traditional sources.

• Epoxy coatings – resins that cure and harden to protect against corrosion.

• Cathodic protection – an additional steel that acts as an anode while the protected metal is the cathode; the anode corrodes instead of the cathode. With careful upfront analysis and the proper preventative measures, corrosion can be mitigated, ensuring that renewable energy infrastructure continues to deliver for years to come. It’s imperative that initiators and

Enabling More Equity-Focused Solar Energy Deployment in the U.S.

Households hardest hit by inflation and rising energy costs are often the ones that can’t get access to solar energy, and the savings that frequently come with it. Families that rent or live in multifamily housing cannot typically install rooftop solar systems. Others can’t afford the up-front costs of repairing a roof or installing solar panels, even though the price has dropped significantly over the last decade.

Community solar – a growing solar development model – allows households to subscribe to a larger solar array rather than installing one on their own roof. A recent study published by the Lawrence Berkeley National Laboratory and the National Renewable Energy Laboratory (NREL) analyzed data from 11 states, and found that people who adopt community solar are over six times more likely to live in multifamily buildings, over four times more likely to rent, and earn 23 percent less annual income than rooftop solar adopters – showcasing community solar as an essential part of equitable clean energy adoption in the U.S.

Community solar projects use sunlight to generate electricity, which flows through a meter to the utility grid. Community solar subscribers (i.e., households, businesses, or any other electricity customer) pay for a share of the power generated by the community solar project, typically in the form of a monthly subscription fee. When the community solar project is located in the same community as the household, there are opportunities for those projects to bring meaningful benefits to their communities. The U.S. Department of Energy (DOE) Solar Energy Technologies Office has invested $82 million in active projects focused on accelerating the adoption of equitable community solar. These projects work to offer a pathway for families to lower their energy bills, and provide community benefits like resilience from power outages and economic development.

Yet, many developers hold off on developing community solar projects, and lenders are reluctant to fund those that do – preventing some communities from accessing solar energy altogether.

When building a community solar project, developers often finance predevelopment funds from a lender. Once a community solar project is up and running, the developer can make money from charging subscribers a small monthly fee, in addition to selling Solar Renewable Energy Credits and taking advantage of tax credits.

While many lenders have developed products to support this market, some developers still struggle to meet the bank’s requirements for a loan. Many lenders

require credit histories from the project’s future subscribers, and proof of the project’s likelihood of success – which can be difficult to obtain before a project is built. When developers do find a lender, loan rates can run into the double digits due to the perceived risk of the project. As a result, many developers are hesitant to build community solar projects that serve low- and moderateincome households for fear they won’t be able to get the financing they need.

Finding solutions

Lynn Heller is Founder and CEO of the Climate Access Fund, a Marylandbased nonprofit. In 2018, along with the Coalition for Green Capital, she established the Climate Access Fund as a green bank that focused on filling these financing gaps that stop community solar developers from serving more low- to moderate-income households.

At the onset, the Climate Access Fund focused on creating a fund that would compensate solar developers for late or defaulted payments by subscribers until those non-paying subscribers could be replaced. While this was helpful to community solar developers, the Climate Access Fund realized that lowcost financing was also needed at the start, in order to encourage developers to serve customers with higher energy burdens. In response, the organization started offering loans. Today, the Climate Access Fund fills a third gap in the market: direct development of rooftop and parking canopy community solar projects that are located in historically disinvested communities.

While the Climate Access Fund has had the resources and expertise to be both a lender and a developer, many organizations aren’t able to do the same.

One way DOE is working to replicate the fund’s success is through our Community Power Accelerator, an online platform that connects community solar developers with investors, philanthropists, and community-based

organizations, with the goal of getting more equity-focused community solar projects financed and deployed.

The Accelerator offers developers resources to get their projects ready to shop around to financiers, including no cost technical assistance, a “Credit-Ready Checklist,” and a popular training course led by the University of New Hampshire’s Carsey School of Public Policy.

To date, the Accelerator has 114 verified projects seeking capital – with 143 megawatts of potential community solar, and over $1 billion in funds committed by capital providers.

The Community Power Accelerator is a part of DOE's larger National Community Solar Partnership, a coalition of community solar stakeholders working to expand access to affordable community solar to every American household, and enable communities to realize other benefits, such as increased resilience and workforce development. The National Community Solar Partnership's goal is to enable community solar systems to power the equivalent of five million households by 2025, and create $1 billion in energy savings for subscribers. This target represents 20 gigawatts of community solar – a near tripling from the seven gigawatts available today.

In a report released earlier this year, NREL estimates that if all technically viable community solar is deployed, it could serve more than 53 million households and over 300,000 businesses in the U.S. that cannot access rooftop solar, representing nearly one terawatt of potential community solar capacity.

The need for more equitable access to solar energy is great, and a challenge that we must overcome to meet our nation’s climate goals and provide a better energy future for all Americans. Developers needing assistance with community solar projects, and lenders looking to finance more clean energy, should check out DOE’s Community Power Accelerator and join the National Community Solar Partnership.

Current AI Trends in PV Plant Monitoring

In 2022, U.S. electricity use was about 4,085 Terawatt-hours (TWhs). By 2035, that use is projected to reach 4,494 TWhs, and by 2050, 5,178 TWhs. As efforts to reduce carbon emissions increase, the use of solar energy in the U.S. is expected to grow from 3 percent of the electricity supply today to 40 percent by 2035, and 45 percent by 2050. Combined with the expanded use of renewable energy and battery energy storage systems, this significant increase in power demand will require the use of advanced AI-enhanced software and other technologies to manage energy plants effectively, and ensure optimal performance.

According to the International Energy Agency, “Power systems are becoming vastly more complex as demand for electricity grows and decarbonization efforts ramp up. […] One of the most common uses for AI by the energy sector has been to improve predictions of supply and demand. Developing a greater understanding of both when renewable power is available and when it’s needed is crucial for next-generation power systems […] That’s where machine learning can play a role. It can help match variable supply with rising and falling demand – maximizing the financial value of renewable energy and allowing it to be integrated more easily into the grid.”3

POWER UP WITH EXEL INTERNATIONAL

In the PV industry sector, AI tools and related technologies provide a faster and more efficient method of processing large amounts of data from PV projects. Insights from these analyses can improve asset management and produce powerful strategic insights for PV plant decisions to maximize return on investment (ROI). Some AI-based processes include automated inspections, performance analytics, energy forecasting, and demand response.

Infrared drones and smart PV inspection tools

Operating a PV plant requires proper maintenance of the onsite equipment to maximize power output. With thousands of modules and hundreds of inverters on a single site, this task is extremely challenging. Until recently, a licensed professional had to walk the site to take photos and infrared scans of sample modules. The expert would then provide general recommendations on how to fix or replace any damaged modules, and sometimes advise resetting power output expectations.

As these processes were time-intensive (since the modules had to be shipped to a third-party laboratory for testing to confirm any observed findings), it would take weeks before systemic issues were identified and resolved. This delay could impair project financing, any Power Purchase Agreements (PPAs), and construction timelines. Recent advancements in Infrared (IR) drones and AI-enhanced software have sped up these processes. Instead of manually collecting sample modules, fleets of IR drones can now scan entire PV sites, making inspections more efficient.

AI-modeled software, such as “smart” PV inspection tools, then can quickly analyze the raw data. In just minutes, these tools can process thousands of images collected from IR flyovers, identifying various performance-affecting assets, classifying their importance, and geo-locating the faulty modules within the plant. These tools ensure that the results are delivered to project owners within a couple of days, enabling for faster response times. Time and money can also be saved by using mobile laboratories at the plant to conduct onsite testing of faulty PV modules.

“Smart” SCADA and Machine Learning tools

Asset performance analysis is another area where AI-enhanced software is helping to obtain more information from supervisory and control data acquisition (SCADA) systems. In the past, SCADA systems only produced monthly reports that offered a high-level overview of system health, but were unable to detect potential production loss due to downtime events or other issues. Today's AI-enhanced “smart” SCADA systems offer more accurate and relevant information along with detailed recommendations. These recommendations can include advice on the best times to wash certain module strings, and information on specific inverter issues, as well as the expected timeframe for critical failures.

Similar to smart SCADA systems, standalone performance analysis has started to rely more on Machine Learning (ML) techniques. ML, a form of AI-enhanced software, provides detailed information on the kind of systemic issues described above. Data is often available at one minute (or even sub-minute) resolution across several years of operation. ML models can process this data for each component at every hierarchical level. These important insights have opened new frontiers for managing PV plants. There are tools currently on the market that can calculate important metrics such as actual performance ratio (PR) for each component, how much energy has been lost during downtime events at the meter level up to the string level, and the optimal behavior of the different device types based on their historical data. These

tools can also conduct separate analyses to determine losses due to various factors such as long-term system degradation, utility-enforced curtailment, soiled modules, and non-functioning singleaxis trackers. Additionally, the tools can calculate actual AC losses between the inverter and point of interconnection.

Some AI-enhanced tools can also finetune forward-looking P50 expectations and identify the most likely causes of underperformance. Another attractive capability of these tools is their ability to process various types of information, regardless of the format. This means that if a portfolio consists of multiple PV plants with different SCADA systems, they can all be integrated into a single platform, thereby centralizing the information and providing a direct performance comparison across assets.

Module defect detection

Anomalies in solar panels can be identified using special cameras that capture IR and electroluminescence (EL) images. If defects are present in a module, specific patterns will be generated, allowing them to be identified and classified. These metrics can be used to create robust ML models capable of automatically analyzing and identifying the areas affected by the defects, and determining their impact on device performance.

Performance analytics

AI-enhanced algorithms can analyze data from sensors and other monitoring devices in real-time to identify inefficiencies and recommend adjustments to improve performance.

Energy forecasting

AI models can forecast the expected production output of PV projects, sometimes days ahead of real-time. This calculation depends on the quality of weather forecasts, and is used by the owners of power plants and utilities to plan daily operations.

Demand response

Utilities employ end-user consumption data to predict future demand on the grid. This enables them to determine how much energy will be needed moving forward. Depending on the situation, operating PV plants can be cut back due to oversaturation, or additional

power stations (e.g., traditional power plants) can be powered up to meet energy demand. AI applications are beginning to play a key role in transforming the solar PV industry. They are improving the efficiency and security of PV plants and driving the transition towards a more sustainable energy system. Looking ahead, we expect research on Large Language Models (LLM) to explore the impact of AI applications on our industry. There are exciting times ahead for clean power!

A Tale of Two Continents Why the U.S. lags behind

When you think of a household appliance, what do you picture? A toaster oven? Clothes dryer? Power tool? We tend to associate “household appliance” with a gadget that doesn’t generate electricity, but requires it. Cords, plugs and outlets are used with no fanfare as long as they serve loads on the electric grid. Which begs the question, why don’t we have appliances that generate electricity for the house, EV, batteries, and the grid?

Good question.

In 2023, Germany saw a quadrupling of legally interconnected Plug-In PV systems. This growth is underpinned by energy policies, electric codes, and safety standards that allow small solar generator systems to connect to the grid as simply as a household appliance. Such advancements have not only democratized solar energy, but have also catalyzed its adoption.

The rise of Plug-In Photovoltaic (PV) systems, or “Balcony Solar,” in Europe presents a compelling model that could revolutionize how North America embraces solar energy. Yet despite the undeniable success of Plug-In Solar in Europe, where regulatory frameworks have evolved to support this innovative deployment method, the U.S. has been slow to

According to Joshua M. Pierce, Professor of Engineering at Western University, “Many advanced countries already allow plug-and-play solar, like the UK and most of continental Europe, yet US regulations have lagged behind. In some areas in the US, small PV installations require no permits, while in others, this is necessary. It depends on the utility and their rules, as there is no comprehensive national law.”1

The bureaucratic complexities extend further with 36,177 Authorities Having Jurisdiction (AHJs) and around ~3300 electric utilities in the U.S., often granting discretionary approval authority to unqualified personnel. This leads to hefty permitting fees and unnecessary project modifications, often based on arbitrary decisions. Such realities particularly exclude commercial and residential renters, as well as homeowners with smaller properties, from participating in the solar energy revolution.

In some jurisdictions, for instance, utilities demand extra liability insurance to protect the electric grid from potential damage by distributed solar generators, despite the technical inability of UL1741-compliant inverters to cause such damage. Additionally, the lengthy approval processes and individual “interconnect studies” required for small generators are not technically justifiable,

Progress amidst challenges: Recent developments

In recent years, the Department of Energy (DOE) has renewed its focus on the potential of Plug-In Solar. This shift in attention has led to efforts aimed at developing a new UL Standard specifically for Plug-In PV systems, marking a significant step forward. The DOE's recognition of the untapped potential for renewable generation, particularly for disadvantaged and underserved communities, is a promising development. These communities, often unable to benefit from traditional rooftop solar due to structural limitations or property ownership issues, stand to gain the most from the accessibility and

with the National Electric Code (NEC).

The path forward: Opportunities and obstacles

The potential of Plug-In Solar goes beyond just individual households. In disaster-

prone regions or areas with unreliable grid access, the ability to quickly deploy portable, grid-tied solar solutions can be a game-changer. These systems offer not only a backup power source, but also a means to enhance community resilience and reduce dependency on centralized power grids.

As the U.S. continues to grapple with the challenges of Plug-In Solar adoption, there is growing recognition that the current regulatory framework may not be adequate to accommodate this new wave of solar technology. The ongoing work with Underwriters Laboratory (UL) to draft new standards, and the discussions surrounding the NEC, are vital steps in this direction. Yet, these efforts must overcome the inertia of existing systems and the reluctance of some stakeholders to embrace change.

One solution is to propose establishing legally permitted pilot sites across various U.S. regions. These sites would demonstrate how distributed, renewable electricity generation can work under real-world conditions, especially for marginalized groups. Mutual energy companies and forwardthinking conventional energy firms can play a crucial role here, leveraging their relationships with AHJs and utilities to establish favorable permitting procedures for such pilot projects.

The ultimate goal is to reach a state of “Nirvana,” where plugin solar solutions like MEGA are seamlessly integrated into our energy systems without cumbersome and inconsistent approval processes. This entails influencing entities like the Department of Energy’s ASRAC Committee and the California Energy Commission to recognize grid-tied electricity generating household appliances (using flexible cords and code-compliant receptacles) as a legitimate category.

Where for art thou, U.S.?

“Balcony Solar” is overdue on this side of the pond. Homeowner or renter, everyone should have the opportunity to take control over how and when they use and store power, whether or not that power is coming off the grid. As AHJs begin to recognize the benign quality of plug-in solutions, individual adoption of renewable energy can thrive. Communities around the country will be better for it – and better able to weather whatever the weather throws at them. The future of electricity generation should not be at the mercy of investorowned utilities and their arbitrary and capricious rules which get rubber stamped by public service commissions nationwide. A comprehensive national law based on solid science that levels the playing field for all stakeholders is imperative. Such a law would eliminate

the privileges and entitlements currently held by incumbent market players, leading to a more equitable and sustainable energy future. As we stand at the crossroads of energy innovation and regulatory reform, it's clear that the path to a greener future is paved with challenges. Yet, with the right mix of technological innovation, policy reform, and collaborative effort, the dream of a solar-powered North America is within reach.

Cable Management Solutions Designed to Lower the Cost of Construction

Unlocking Shared Rooftop Solar for Multifamily Residents

The Environmental Protection Agency's (EPA) Solar for All initiative is a transformative program designed to bring the benefits of solar energy to low-income and disadvantaged communities across the United States. With a substantial $7 billion in funding, this initiative aims to expand access to affordable, resilient, and clean solar energy, targeting the deployment of residential rooftop solar, community solar projects, and storage solutions. While the current focus has largely been on low-to-moderate-income single-family homes and community solar, an often-overlooked opportunity lies in multifamily buildings

Current focus and challenges

The majority of Solar for All funding is currently directed towards low-to-moderate-income (LMI) single-family homes and community solar projects due to their easier implementation and proven benefits. Where a single-family home installation typically involves fewer stakeholders and simpler logistical planning, making it more straightforward to execute, multifamily buildings – particularly those housing low-income residents – present a significant, yet underutilized opportunity.

Deploying solar in multifamily settings, however, is inherently more complex than single-family homes for several reasons:

1. Technical and logistical hurdles: Historically, multifamily solar installations required multiple systems (one for each unit) which is cost-prohibitive for building owners.

2. Split incentive problem: Solar benefits, primarily in the form of lower utility bills, flow more to tenants than building owners, discouraging investment.

3. Complex ownership models: Multifamily buildings often have intricate ownership structures, complicating decision-making and prolonging the process.

4. Financial constraints: Affordable housing developers operate on tight budgets, making large upfront investments challenging; these developers often work with margins as slim as 3-5 percent, limiting capital for projects like solar installations.

Limitations of Community Solar

While community solar is a crucial solution for providing energy equity to low-income communities, it also has its limitations:

1. Geographical constraints: As of 2020, only 20 states and Washington D.C. had policies supporting these projects.

2. Reliance on third parties: Community solar depends on third-party entities, utility policies, and specific programming, which can vary significantly by region.

3. Billing issues: Complex billing processes can lead to errors and confusion. One survey indicated that 65 percent of community solar customers experienced billing issues within the first year.

4. Reduced financial benefits: Community solar participants often see savings of 10-20 percent on utility bills, compared to 40-70 percent with direct rooftop solar. This difference can significantly impact the financial viability and attractiveness of community solar projects.

Innovations Facilitating Multifamily Solar

Despite these challenges, recent technological advancements and innovative business models have made direct rooftop solar consumption feasible for multifamily buildings:

1. Innovative solar distribution systems: New systems allow multiple units in a building to share a single solar installation, reducing the need for individual systems and cutting costs significantly. These advancements can lower installation costs by up to 30 percent, making solar more accessible for multifamily buildings.

2. Battery storage: Integrating solar with battery storage enhances resilience against extreme weather and blackouts, providing uninterrupted power. The cost of battery storage has decreased by 87 percent from 2010 to 2020, making this more viable and attractive for multifamily buildings.

3. Direct ownership models: These models protect customers from reductions in net energy metering (NEM) policies, ensuring they capture the full retail rate of electricity. Direct ownership systems have shown 15-20 percent higher savings compared to third-partyowned systems in initiatives like the California Solar Initiative.

Importance of Multifamily Solar

Focusing on multifamily buildings for solar deployment is crucial for several reasons:

1. Density of beneficiaries: Multifamily buildings house more residents who can benefit from rooftop solar; a 50-unit building can provide solar benefits to 50 families, compared to a singlefamily home benefiting one family. This density amplifies the impact of each solar installation.

2. Higher energy burden: Lowincome multifamily residents typically face higher energy burdens compared to single-family home residents. Reports show these households spend three times more of their income on energy costs compared to the average household, making energy savings from solar particularly valuable.

3. Energy equity: Enabling direct solar consumption for multifamily residents helps address energy equity, involving more communities in the clean energy transition.

Strategic Recommendations for Solar for All Winners

For the winners of the Solar for All funding, strategically including multifamily buildings in solar

deployment plans can drive significant growth and community impact. Here are key recommendations:

1. Leverage policy incentives: Take advantage of federal, state, and local incentives aimed at promoting solar in multifamily housing. Policies such as the Investment Tax Credit (ITC) and specific grants for low-income housing can offset installation costs and improve project viability.

2. Collaborate with affordable housing developers: Partnering with developers of affordable housing can facilitate the integration of solar into new and existing multifamily buildings. These collaborations can align financial and environmental goals, making solar projects more attractive.

3. Seek expertise from multifamily solar specialists: Engage with experts who understand the unique challenges and needs of multifamily solar projects. These specialists can help navigate the complexities of ownership models and financial considerations, ensuring successful implementation.

4. Ensure incentives align with financial considerations: Design incentives that meet the financial goals and expected returns of multifamily building owners. Attractive incentives are crucial for encouraging investment in solar installations.

5. Promote energy equity: Create programs that incentivize building owners to share higher percentages of their rooftop solar generation with their residents. This approach not only supports energy equity but also enhances the overall community impact of solar projects.

Conclusion

Solar for All funding has the potential to significantly impact low-income communities by supporting solar projects in multifamily buildings. These buildings house many residents who can greatly benefit from direct solar consumption. While deploying solar in multifamily settings is more complex, innovative solutions available today make it feasible. Grant recipients must recognize the untapped potential of multifamily solar and include these projects in their plans to ensure a more equitable distribution of clean energy benefits. By addressing the challenges and

leveraging the latest technological innovations, Solar for All can ensure a more inclusive and impactful deployment of solar energy, benefiting a broader range of communities and contributing to a sustainable and equitable energy future. The solar industry has a unique opportunity to drive this transformation, promoting not only environmental sustainability but also social equity through strategic and innovative approaches to multifamily solar deployment.

Finding New Life for PV Glass and Silicon

One of the biggest hurdles to panel recycling in the U.S. today is that solar glass and cells are not being separated and recovered for their value. Panel shredding is the most common process; at best, it recovers value for aluminum, silver, and copper, leaving other valuable materials clinging to the glass that goes to the landfill. Glass disposal fees cost recyclers, further driving profits down and extending those costs to wellintentioned, recycling customers. There’s much room for improvement in module material recovery.

A new set of processes to address the many module material recovery intricacies will soon be available in the U.S. These processes start by recovering more from end-of-life (EOL) modules, including historically challenging glass and silicon. They involve removing the junction box and aluminum frames, followed by separating glass from the backsheet, Ethylene Vinyl Acetate (EVA), and cell using machines. This is just one solution in a toolset being developed for handling various types of panels with integrity and payback.

EVA is the glue that holds the glass, solar cell, and backsheet together on nearly all modules. Much like a shatterproof adhesive in windshields PVB (polyvinyl butyral), EVA acts as a binder that holds shards together when breakage occurs. EVA is the goal constituent to break down in panel value recovery so that glass can be pulled apart from the cells successfully with little to no metal contamination.

The glass that is mixed with silicon equals little to no silicon recycling and limited glass recycling, if not more than 99 percent clean. U.S. glass manufacturers don’t accept solar glass because of its antimony contamination. This antimony contamination limits the use of solar glass in recycling programs for two primary reasons. The first is that contamination of the antimony in the glass matrix is enough to trigger waste management issues when used for sandblasting and anything designed to be placed on the ground or incorporated into the soil. The second is that the majority of glass furnaces in North America use significant amounts of glass cullet to produce float glass and fiberglass. These processes are very sensitive to metal contamination in glass oxides.

The successful recovery of solar glass and silicon in the U.S. marks a milestone in advancement for the solar recycling industry. A new, off-the-shelf process to separate glass from silicon cells is 80 percent more efficient than current recycling machines, producing 100 percent purity, has a lighter footprint, and is cost-effective.

With increased purity of the silicon recovered, value will be added to each panel, driving per panel recycling costs down. Silicon currently hasn’t been a recoverable element in modules, often locked into glass and backsheet scraps that go to the landfill. Now, high purity silicon can support domestic semiconductor

manufacturing, putting critical materials back into the system.

These recycling advances will improve current market solutions, increasing the recovery of the metal and other valuable commodities locked within the solar panels, while properly addressing the reuse of solar panels through verified partners with welldocumented and developed quality control programs. It’s a simplistic approach that tackles one problem at a time, while maintaining awareness of the market conditions existing on a global scale to solve these problems.

The ability of multi-national glass reclaimers to turn the antimony-laden glass materials into newly manufactured products like porcelain toilets, glass blocks, and even new solar glass, marks a major boost towards a full circular economy approach in solar.

Finally, cost-effective PV recycling

Panel recycling is known to be expensive, with the average cost of recycling a solar panel ranging from $15 to $45. A few mechanisms drive costs; the main driver is the failure to recover more value from materials and find a profitable host of buyers. Adding in the cost to run a plant, the machinery, certification costs like R2 Certification, labor to check panels, the cost for logistics both to the facility and to the buyer (often overseas), and tipping fees, and the industry is looking at prohibitive expenses.

By accounting for these costs by recouping all potential value instead of passing those high costs along to the client, the process becomes more widely achievable.

The need for transparency

A major rumbling in the solar recycling industry is emerging, and it will only be solved with verified traceability –both for reused panels, which should be responsibly traced when re-routed for use, and recycled panels, where recycling certificates may not represent true recycling. Since the solar panel recycling industry is still relatively new, many major players are trying to find their profit footing, regrettably finding it necessary to forgo their earlier recycling promises. Certifications and reports may not be enough to detect these actions. That’s where e-waste tracing dashboards will serve larger entities like developers and utilities in delivering transparency for ESG and impact reporting.

The only way we can start making module recycling mainstream is by clearing the current market roadblocks. This will go a long way in creating the many solutions that will lead to an avalanche of transparent, affordable panel recycling in the U.S.

Unlike traditional power plants, wind turbines face unique challenges in maintaining their generators due to the absence of scheduled turnarounds, and the logistical hurdles of sending equipment to a service shop. This article explores the significance of preventative maintenance inspection and overhauls for wind turbine generators, emphasizing the need for innovative up-tower solutions to minimize downtime and costs while maximizing turbine performance and longevity.

Generator maintenance in conventional power plants typically involves planned turnarounds or unplanned shutdowns, facilitating in-place or off-site overhauls. These procedures encompass essential tasks such as bearing replacement, cleaning, balancing, and testing, with more complex repairs occasionally necessitating component replacements or machining. However, the dynamic nature of wind energy presents distinct obstacles to this conventional approach. Wind turbines lack scheduled turnarounds, making it challenging to coordinate maintenance activities efficiently. Moreover, transporting a generator to a service shop entails considerable expenses, including crane usage and the provision of spare equipment, substantially inflating maintenance costs.

The evolving landscape of wind turbine manufacturing further complicates generator maintenance. Original Equipment Manufacturers (OEMs), in their pursuit of cost reduction and competitive advantage, often compromise component design, including generators. This compromise can lead to increased vulnerability to wear and tear, exacerbating maintenance challenges. Additionally, as OEMs push for taller and higher-capacity turbines to enhance energy output, the complexity and cost of generator swaps escalate significantly. Consequently, the traditional maintenance paradigm becomes increasingly impractical and cost-prohibitive, necessitating innovative solutions.

Generator service contractors specializing in preventative maintenance play a pivotal role in addressing these challenges. By leveraging expertise in up-tower repairs and unique solutions, these contractors extend turbine lifespan, mitigate the risk of catastrophic failures, and potentially qualify for repower credits. Up-tower maintenance involves conducting inspections, repairs, and overhauls directly on the turbine, eliminating the need for costly disassembly and transportation.

Up-tower maintenance techniques encompass a range of innovative approaches tailored to the specific needs of wind turbines. These include remote monitoring systems for early fault detection, modular repair kits for on-site component replacement, and advanced diagnostic tools for in-depth analysis of generator health. Furthermore, advancements in robotics and drone technology enable precise and efficient inspection and maintenance tasks, even in challenging or hazardous environments. Condition monitoring and

inspections are invaluable for decision making, but they don’t solve maintenance challenges. Some contractors are developing unique tooling that allow for up-tower WYE ring replacement, rotor machining, dual plane balance, rotor re-banding, rotor removal for stator wedge repairs, and much more – all up-tower. By embracing these up-tower solutions, wind farm operators can streamline maintenance operations, minimize downtime, and optimize turbine performance.

Emphasizing preventative maintenance is crucial for maximizing the return on investment in wind energy infrastructure. Regular inspections and overhauls not only extend the operational lifespan of generators, but also enhance overall turbine reliability and efficiency. By proactively addressing potential issues, operators can avoid costly downtime and emergency repairs, ensuring uninterrupted power generation and maximizing revenue. Moreover, preventative maintenance fosters a culture of safety, compliance, and sustainability, aligning with the broader objectives of the clean energy transition.

In the dynamic landscape of wind energy, effective generator maintenance is paramount to ensuring the reliability, efficiency, and longevity of turbines. Traditional approaches to maintenance, reliant on scheduled

turnarounds and off-site overhauls, are increasingly impractical and cost prohibitive. Instead, the industry must embrace innovative up-tower solutions that enable efficient, costeffective, and proactive maintenance directly on the turbine. By partnering with experienced generator service contractors and leveraging cutting-edge technologies, wind farm operators can optimize performance, minimize downtime, and drive the continued growth of clean energy across North America.

Extreme Testing

When operating conditions for wind turbines call for advanced oil analysis

Advanced oil analysis tests for wind turbines should be conducted whenever a routine test picks up a significant anomaly, when trending analysis flags a pending negative condition, or when the manufacturer notifies operators of a possible defect that warrants a closer look. Following are three advanced oil analysis tests that make sense for wind turbines.

Filter debris analysis

Filter debris analysis (FDA) identifies abnormal wear in critical operational assets by measuring specific wear metals captured in the filter. A systematic process, similar to that used in the military, has been developed to wash and analyze the types of filters most commonly used in wind turbines. Advantages of FDA include:

• The full-flow nature of the filter element allows all the fluid in the system to pass through the filter element, providing an accurate assessment of the fluid and equipment condition.

• The coherent surface for capturing fluid system debris efficiently over time results in a high concentration of debris, compared to debris in the fluid or in magnetic plugs/chip detectors.

• The filter element retains debris of all types (metallic and nonmetallic). With traditional oil analysis, the only particles available for analysis are those circulating in the oil (smaller than the filter size) or immediately released in the oil prior to filtering. Given the fine filtration used in today’s wind turbine gearboxes, 95 percent of the wear debris that could provide useful insight into machinery condition is caught in the filter, and never ends up in an oil sample. Typically, this valuable debris is discarded with the filter. FDA captures this lost information to identify the specific components that are wearing, providing improved diagnostic and prognostic information about impending failures.

Foam

ASTM D892 measures the foaming tendency of a lubricant. Even though foaming is a fundamental physical property of a lubricating fluid, the tendency of oils to foam can be a serious problem in systems such as high-speed gearing, high-volume pumping, and splash lubrication. Inadequate lubrication, loss of lubricant, and cavitation can lead to mechanical failure. Cavitation is the formation of air or vapor bubbles in the fluid due to lowering of pressure in a liquid; these bubbles then collapse (implode) in the higher-pressure regions of the oil system. The implosion can be powerful enough to create holes or pits – even in hardened metal – if the implosion occurs at the metal surface. This type of wear is most common in hydraulic pumps, especially those that have restricted suction inlets or are operating at high elevations.

ASTM D892 measures foam by three sequences that differ only in testing temperature.

• Sequence I measures the foaming tendency and stability at 24°C (75°F).

• Sequence II uses 93.5°C (200°F).

• Sequence III uses the same conditions as Sequence I, except it’s performed on fluid that has just been measured in Sequence II.

The fluid sample from Sequence I is only used for that test. The fluid sample used in Sequence II is carried into Sequence III. The results are reported as two numbers for each sequence. For example: 20/0 means 20 milliliters of foam tendency was measured after 5 minutes of aeration followed by no foam stability (0 ml) after the 10-minute settling time. Most new oil specifications require 10 to 50 milliliters tendency maximum and 0 milliliters stability.

Compatibility testing

Almost everyone that has worked in the reliability field has either experienced or heard about a lubrication problem brought on by combining incompatible lubricants. Sometimes this is accidental, such as a leaking hydraulic line dripping onto a gearbox. Other causes are intentional, i.e., the plant wants to consolidate the number of lubricants in use, the current product is discontinued, or there are supply chain issues. In any case, compatibility testing is required.

Problems with compatibility include excessive foaming, precipitate or deposit formation, and loss of essential performance traits such water separability. It’s also important to remember that “equivalent” or “comparable” lubricants are not the same as compatible lubricants. Two considerations for determining the best compatibility test or test slate are:

1. Decide if you will test your current in-use fluid with the replacement fluid(s). If you have one lubricant system that’s transitioning to a new oil, it’s a good idea to test the used fluid with the replacement fluid. This will detect any possible incompatibilities between the used oil and new oil. If you have multiple systems that will be changing to the new oil, then comparing a new oil sample of the fluid currently in use in the machines to a new oil sample of the replacement fluid will provide a basic determination of compatibility. Alternatively, a used oil sample from each of the systems can be tested with the replacement fluid.

2. Determine which mixtures you would like tested. ASTM D7155 calls for at least one mixture in the ratio of 50:50. Additional mixtures can be added if appropriate. Even with a complete change out, some residual fluid may be present in the system and could mix with the new fluid. In that case, adding a mixture of 90 percent new oil to 10 percent used oil is recommended. If the replacement fluid will be gradually added to the existing fluid, then three mixtures are recommended, either 90:10, 50:50, and 10:90 or 25:75, 50:50, and 75:25.

Compatibility testing will identify incompatible lubricants before they are mixed in equipment and cause operational issues. Alternative choices can then be evaluated so that a suitable replacement can be selected. While lubricant compatibility testing cannot guarantee compatibility, it can predict it.

Depending on the specific type of equipment and suspected issues, there are a number of other advanced oil analysis tests that could be run on wind turbines. The key is to work with a trusted lab for all testing, both advanced and routine.

The Talent Updraft

Recruitment, retention, and accountability as a blade technician

Picture this: You are sitting around a table, breaking bread with a group of wind technicians, when the conversation turns to how they all got into the business. To me, this is an especially relevant topic, as it might help with recruiting more talent into the business.

Here’s the interesting thing – most of the technicians got here because they knew someone already in the business. Take Zach, for example. His uncle recruited him. Len? Recruited by his brother. Tomas? Recruited by his friend Len.

Len expanded on why he stays in the wind industry. His brother actually had to work pretty hard to get him to try working on a blade repair crew. Once he started, though, he was hooked. He found the work challenging and rewarding. What he really loves, though, is being held accountable. His work and reputation matter to him. People count on him to do good work, without short-cuts. Developing a positive reputation and continuously expanding his skills drives him to stay in the industry, and to excel.

Frank has been in the business over 20 years, occasionally boomeranging in and out – as he says it “as the wind blows.” He keeps coming back as he loves the work, the travel, the teamwork, and loves teaching others the craft of blade repair.

One story was different from the others. Drew got out of the military and went to his local community college. He was deciding between learning the trade of diesel mechanic or wind technician, both of which were suggested by a counselor based on Drew’s skills and aptitude. He chose wind because he figured it would be more promising and represented an interesting future. He stays because it’s a fascinating, evolving, and important industry.

The conclusion I reached is that, for the time being, word of mouth is the industry’s most powerful recruiting tool. How can we leverage that power? With testimonials on social media? Stunning images? Since there don’t seem to be enough technicians for the available work, maybe that could help.

Unpacking some of the stories further, I wondered how Len and Tomas knew each other. As it turns out, they both worked in the composites industry (boats, to be specific). Industries like boat manufacturing, bicycle manufacturing, aerospace, and even prosthetics, all share similar technologies. More intriguing is that these industries represent transferable skills for blade repair. Can wind recruit from those industries?

Here is a real-world example. A well-known farm equipment manufacturer is laying off people in Illinois and Iowa due to a downturn in agriculture. Meanwhile, a group that makes nacelles plans to restart production in its manufacturing facility in central Iowa. Could this be an opportunity for the wind industry to gain manufacturing talent?

Back again to the dinner table with the technicians – the conversation turned to why people stay in the industry; that list was particularly telling. The number one reason is that people like the work. They take pride in the skills they have developed, some for over 20 years. They like the challenge. They like the travel. They like the teamwork. They like the money.

It’s also useful to understand what people don’t like. Not surprisingly, they don’t like the seasonality, and being laid off for extended periods of time. Some wonder if long-term exposure to the chemicals and fiberglass are safe, and if the PPE is enough. Those, however, seemed to be the only negatives.

I also wondered: How did people build their skills? Sure, some went to trade schools and community colleges, but the majority at the table learned through an apprenticeship program, mentors, and on-the-job training. This was appealing, as it didn’t require the upfront investment in time and money associated with a traditional college track. Gen Z is increasingly choosing the trades over college because it’s a straight path to a job, and they don’t want desk jobs. Plus, Gen Z doesn’t want to be burdened with student loan debt. According to the American Wind Energy Association (AWEA), the wind industry has experienced rapid growth. Just 24 years ago, installed wind energy capacity in the United States was under

3,000 megawatts. Today, it is over 35,000 megawatts, enough to power almost 10 million homes. This growth is expected to continue. The U.S. Department of Energy states that it is feasible for wind power to provide 20 percent of U.S. electricity needs by 2030. That translates into needing more talent, especially as some of those 20+ year veterans consider retirement.

To summarize the findings from my dinner table conversation with almost two dozen technicians, the blade repair space is a good sector to enjoy interesting and rewarding work that pays a good wage. Most entered the business through referrals and stay because they like it. It also helped that they didn’t need a large initial investment of time and money.

Some ideas for adding talent, when and where we need it, include formalizing the referral process – recruiting from industries with transferable skills or industries suffering an economic downturn, and spreading the word that the wind industry is a growth industry with a bright future. You must hold yourself accountable, though, if you plan to stay.

Turbine Technology Assurance

A new frontier amidst rapid growth in the offshore wind sector

We have seen an unprecedented pace of wind turbine technology evolution in the past decade, driven by an operator-based need to reduce the levelized cost of energy (LCOE) ahead of looming net zero 2050 targets.

New turbines come with a great variety of designs, increasing in complexity to balance increasing power ratings and CAPEX. These innovations have thus far delivered significant reductions in LCOE, but they also face compressed design and prototyping cycles, and come with a reduced field track record. As a result, higher rates of early design failures and longer replacement times for components now plague windfarms both on and offshore.

Floating offshore technology, for example, showed a lot of promise in delivering wind energy to previously inaccessible areas, but remains challenging for cost effective operations and maintenance. The remote nature of floating turbines means major component replacements are more complicated. In the UK, for instance, turbines must be towed to other European countries as domestic port infrastructure isn’t yet advanced enough.

You will often hear this referred to as the ‘bathtub curve’. New designs are trialed with an initial flurry of issues expected, until design analysis allows identifying sensitivities which may have been overlooked. Once detected, these can be fixed; the expected number of failures will decrease, settling into a constant failure rate at lower levels until an asset begins to age, and failure rates increase again. With the record installed capacity in 2023, and significant aging fleet, wind operators must deal with managing reliability on existing fleet as well as early design issues with new turbines. Digital technologies have a key role to play in managing reliability issues, regardless of the life stage.

You don’t have to look far to see the impact of this. A major industry player recently suffered an unfortunate string of high-profile malfunctions that were widely documented. Wind asset advisory groups have recognized reliability concerns as a key obstacle to securing investment in the industry, for both lenders and developers.

Tackling these emerging issues requires using the toolkit available, and starting with data. Early implementation of digital technologies that allow assets’ performance and health to be monitored can remove this new level of uncertainty around project profitability.

Predictive maintenance technologies (PdM) in particular can play a fundamental role in maximizing component value throughout a turbine life cycle. By ensuring planned maintenance, reducing turbine downtime, and ultimately avoiding catastrophic failures, it has been shown that the implementation of PdM on an onshore site can provide an almost three-fold return on investment.

Utilizing organizations that can independently provide products and services to enable predictive maintenance will reduce the burden on operator O&M budgets from the outset. Available services include a free database covering more than 75 GW of installed wind capacity, and over 20,000 turbines 1. Across these turbines, over 9,000 faults have been identified to date, demonstrating the value in adoption digital applications. The early intervention allowed by CMS is vital in this period of rapid expansion for the wind industry, providing room for learnings to inform new design cycles moving forward.

While the fast deployment of advanced renewable technology is inarguably required for the UK’s net zero 2045 target to be within touching distance, there has been definite consequence for the speed of growth the industry has been forced through. As the industry looks to extend the operational capacity of turbines, we must acknowledge that we don’t yet have an accurate assessment of potential drawbacks.

Condition monitoring software, a key discipline of predictive maintenance, is a crucial factor in enabling a thriving, long-term future for the wind sector. To improve the industry’s chances of capitalizing on the ‘green boom’, we must become more investable, and that requires improving the confidence in assets’ operation.

Safeguarding Vital Wind Farm Equipment

When the shift to clean and more renewable sources of energy in the United States began earlier this century, the growth of wind farms increased dramatically. It seemed like almost overnight, large wind turbines by the dozens or hundreds suddenly appeared in farm fields and other open spaces.

Wind power facilities, despite their environmental benefits, face a growing threat from theft and vandalism. These remote installations have become prime targets for criminals, particularly those seeking valuable copper from power cabling. The impact on wind farm operators is significant, with each incident potentially causing substantial financial loss and operational disruptions.

As the industry grapples with this challenge, innovative security measures are becoming essential to protecting these vital renewable energy assets.

To address these concerns, wind farm operators are developing comprehensive security plans ,including proper lighting, alarm systems, fencing, and by installing high security weather- resistant mechanical locking devices to deter theft.

A case study of a major player in the clean energy industry details their use of high security padlocks, which they started employing 16 years ago. Confronted with several challenges to finding the padlock that would best suit their specific wind energy application needs, they highlighted two foremost concerns: they needed an extremely secure solution, and it had to perform well under a variety of demanding conditions. Today, over 1,000 specialized locks protect nine of the company’s wind farm properties in four states, stretching from Colorado to Pennsylvania.

A compliant solution to stay ahead of regulatory changes

As wind became the largest source of renewable power in the United States, so did the stakes to secure properties. NERC Critical Infrastructure Protection (CIP) guidelines are regularly updated with greater requirements for operators to implement measures to ensure their protection from physical attacks that may result in power outages. The rates for both cyber and physical threats have risen, due mainly to the remote locations and the inadequate security at the properties. But critical infrastructure being vulnerable is not just limited to wind farms.

A few years ago, a university research team was hired specifically to identify security weaknesses at powerplants in the United States. They were able to pick a tower door lock on a wind turbine in less than one minute, access its automated controller, and shut it down remotely, from miles away.

Most utility operators have since responded appropriately with a combination of physical deterrents and technology. Just as there are various cyber deterrents in use to safeguard wind industry technology, there are also several types of durable high security padlocks protecting wind farms across the U.S. Some operators prefer a lock with a hardened steel body frame and a case hardened, 3/8-inch boron steel shackle. This tends to be a natural fit for wind farm applications because the body is resistant to drilling and grinding attacks, and the shackle is even more stubborn to cutting and grinding attempts.

A best practice is to look for a lock with a special built-in protection device that includes a rotating disk cylinder. This makes it pick resistant and completely bump proof, a common problem associated with pin tumbler padlocks; wind farm managers have found it to

helpful keeping turbine doors and junction boxes secure. Some use it to protect their MET (Meteorological Evaluation Towers) access and perimeter gates and fences, as well as the storage connexes, transformer doors, and air intakes.

A major Midwest wind farm has used ALCEA padlocks for over 15 years.
The padlock must haves an excellent operational track record despite a wide variety of weather conditions they have will be subjected to.

Having a rekeyable padlock is important considering the number of people who may have keys. The beauty of an integrated electromechanical solution is it allows you to control and manage key access rights for employees and contractors remotely. This includes deleting lost keys when it happens (and it does) and having access to audit trail reports, all in real time.

Secure access in all weather

Most wind farm managers will utilize a regular maintenance schedule for their padlocks that includes a physical inspection. Given their location, some of these locks may go over a year without being opened. Others, such as the turbine door locks, might be opened a minimum of every three months.

A wide range of weather conditions also comes into play when looking for the right solution. Padlocks are subjected to every type Mother Nature has to offer, from the snow and sub-freezing conditions in the mountain ranges, to the hot and dry conditions across the plains.

There are padlocks with built-in advantages that can withstand the repeated exposure of any weather situation. Look for ones with cylinders that are environmentally durable, and those with a surface treatment that offer corrosion resistance for both the outer and internal components.

Padlocks rated IP68 give you protection from dust and water, and those with a fully sealed pressure cap will prevent dirt, grime, and moisture from having any chance of entering into the cylinder. One property manager had their locks survive a “100-year flood” five years ago. Two weeks after the water receded and workers were finally able to locate them buried deep in mud, they still worked – flawlessly.

The bottom line is this: If your wind farm property experiences a lot of dust, dirt, snow, and ice, there are high security locks that exist with proven performance records to handle just

about anything that’s thrown at them. Not only will they give you peace of mind and protect your equipment, they’ll also keep you compliant with today’s NERC CIP security guidelines – giving you the extra time you need to focus and manage all the other aspects of your job.

2023 Atlantic Hurricane Season Review

Impacts at U.S. east coast offshore projects

TFigure 1: 2023 Atlantic tropical storm tracks. The four named storms that traveled closest to the U.S. east coast are labeled and color coded. Offshore wind lease areas are also shown as colored polygons, and the five floating LiDAR buoy locations are marked as red dots.

ropical storms and hurricanes pose a unique challenge for offshore wind farm development in the Gulf of Mexico and along the U.S. eastern seaboard. Several collaborative studies are currently underway to understand, model, and quantify the risks of tropical storms to offshore wind farms, including the Tropical and Extratropical Storm Impacts on Future Offshore Winds (TREXO) project led by Argonne National Laboratory. In this analysis, we will review the 2023 Atlantic hurricane season, focusing on the tropical storms that affected the primary wind development regions along the U.S. east coast from North Carolina to Massachusetts. Our data sources for wind and wave data are the ECMWF Reanalysis v5 (ERA5) model data set and measured observational data from five floating LiDAR buoys deployed by TGS sited along the U.S. east coast. 2023 Atlantic hurricane season was quite active, producing 20 named storms. Here we focus on the four named storms that traveled closest to the offshore wind development regions along the U.S. east coast: Hurricane Franklin, Hurricane Idalia, Hurricane Lee, and Tropical Storm Ophelia. Figure 1 shows the storm tracks of these four storms along with the offshore wind lease areas and the locations of the five floating LiDAR buoys.

Figure 2: ERA5 wind speed model data (dark blue) at 137m above mean sea level and ERA5 significant wave height (turquoise) model data at each of the five buoy locations. Background color shading denotes the timing of the four named tropical storms during the analysis period: Hurricane Franklin (blue), Hurricane Idalia (orange), Hurricane Lee (green), and Tropical Storm Ophelia (light blue).

Hurricane Franklin did not make landfall in the U.S. but peaked as a Category 4 storm with winds of 150 mph on August 29th. Hurricane Idalia made landfall on the gulf coast of Florida, then crossed over Georgia and South Carolina before reentering the Atlantic Ocean early on August 31st. Hurricane Lee was a long-lived storm, first reaching hurricane strength on September 6th, then making a noticeable turn to the north on September 13th thereby avoiding the U.S. east coast before making landfall in Nova Scotia on September 16th. And lastly, in contrast, Tropical Storm Ophelia was a short-lived storm sustaining tropical stormforce winds for only two days before making landfall on September 23rd in North Carolina. Given the timing of these storms, we will review wind speed and wave height data from August 27th through September 25th. Our analysis will focus specifically at the five floating LiDAR buoy locations which are situated close to the primary wind development regions along the U.S. east coast, including the Massachusetts offshore projects, the New York Bight wind farms, and the Central Atlantic wind leases.

Figure 2 displays the modeled ERA5 wind speed and significant wave height data at each of the buoy locations. The background color shading denotes the timing of the four storms where the color corresponds with the storm tracks from Figure 1. Hurricane Franklin only had a minor influence across the five sites, resulting in a small increase in wave heights at the southern buoy locations. Hurricane Idalia had a more noticeable influence at the two southern buoys where wave heights and wind speeds were strong as

the storm passed to the south. Farther north, Idalia again did not have much impact. While Hurricane Lee maintained a good distance from the offshore wind projects, the storm persisted long enough to generate strong swells across the region. And stronger winds, close to 20 m/s (45 mph), are also seen at the Massachusetts site as Hurricane Lee passed by to the east. Lastly, Tropical Storm Ophelia had the largest impact of the 2023 storms. Given the storm track, the strongest wave heights and wind speeds were recorded across the southern Central Atlantic, but positive wind and wave anomalies were felt all the way up to Massachusetts.

The measured data from the five floating LiDAR buoys correlate well with the ERA5 model data and reveal a similar overall picture, but important differences are also apparent. Figure 3 presents a comparison of the measured significant wave height data and the ERA5 model data at the southernmost buoy. This buoy location measured the highest wave heights associated with the 2023 tropical storms. While the timing of the wave height peaks is similar, the ERA5 model data underestimate the maximum wave heights observed during each storm. This is especially true during Tropical Storm Ophelia when the measured significant wave heights are over 1.5m higher than the ERA5 model data. Additionally, the measured data are much more variable on shorter time scales, which ERA5 does not capture. Such differences can be critically important when calculating the design criteria for wind turbine foundations and engineering loads analysis. Relying on model data, such as ERA5, could lead to significant and very costly errors.

The 2023 Atlantic hurricane season did not produce any storms that directly hit the U.S. east coast offshore wind leases. Tropical Storm Ophelia came closest and had the largest wind and wave anomalies, delivering winds over 25 m/s (55 mph) and significant wave heights near 7 meters (22 feet). The maximum wave height measured during Ophelia exceeded 18 meters (60 feet), which is a good reminder that very large anomalies are possible even during storms that are not rated as hurricanes. Measuring anomalous events is very valuable and gives engineers realworld data to rely upon in their calculations to ensure the survivability of wind turbines during such extreme conditions.

Madison Chemical introduces ALUMA-BRIGHT FOAM, an acidic cleaner containing a balanced blend of surfactants and acids for cleaning and brightening aluminum alloys through a moderate etching process, including welds. This blend of surfactants and acids provide the ability to wet out the surface, as the surfactants help the acid penetrate the soils and tramp oxides and allows the liquid to flow across the topography surface well. This also helps to penetrate the various grain boundaries, inclusions, voids, and other imperfections in the surface well. Primarily intended for soak or foam applications, this unique product has a mild, pleasant odor. Suitable for subsurface cleaning and removal of subsurface staining. In addition to cleaning welds, it removes soil and scale buildup, rust blush, rust back, flash rust, and other forms of oxidation, lime, and other scale deposits from drain vestibules during the descaling of the bath stages or recirculating spray washers. It is also helpful in targeting laser scale, heat treat scale, weld marks, red oxides, aluminum smut, plasma smoke residues, and more. ALUMABRIGHT FOAM can be used at 65°F to 180°F at concentrations of 1% to 10% by volume with water.

Visually inspecting inside wind turbine blades

Clobotics Wind Services’ Clobotics Crawler (code named KIWI) robot is a device built for safely, rapidly, and cost-effectively documenting the internal condition of wind turbine blades. The device features two high resolution, high dynamic range (HDR) cameras, LED lighting, and a tethered line for retrieval. The robot weighs approximately 6kg and is 20" x 9" x 11" (50cm x 23cm x 28cm). By gathering and analyzing image data from both the inside of blades, with the Clobotics Crawler, and outside of blades, with the Clobotics IBIS drone inspection system, operations and maintenance managers can make informed decisions about where to focus attention and allocate resources for further investigation and follow-up action using the Clobotics IRIS cloud data platform. The basic steps of an internal inspection using the Crawler include data collection from the site and upload to the cloud with a focus on low cost, high quality, and maximum safety. Once in the Cloud, IRIS labels points of interest or defects seen in the images and analyzes statistical trends, generates reports, and develops action steps, while securely connecting to the Clobotics IRIS platform. Safety is enhanced as the robot can be positioned in the blade and conduct the inspection without requiring a technician to physically enter the blade. Quality is achieved by using industrial cameras configured to capture every surface with a novel lighting approach and 26 megapixels of resolution, and 100% image coverage of up to 2/3 of the blade length, as well as identifying the distance from the blade root of images and points of interest to within 7.9" (20cm) of ground truth. Using the Clobotics Crawler, a team of two technicians can expect to safely inspect two entire wind turbines in a single day.

How I Built a Microgrid in the Middle of Nowhere

The possibility of working remotely has opened opportunities for millions of people. As an avid outdoorsman, I have been building a retreat in western Montana. In this case, the word “remote” is an understatement; there is no electricity, cell phone service, or internet access – it’s entirely off the grid. But I need those things to live and work here, so I had to build my own. Here’s how I did it.

People have historically moved to where the work is. The Gold Rush in the 1800s created whole towns near mines in the American West. The Dust Bowl drove a large percentage of Oklahoma's population to California’s Central Valley and its agriculture jobs. More recently, high-technology companies have turned Silicon Valley into a hub for millions.

When the COVID-19 virus struck in 2020, the possibility of working remotely suddenly became necessary. Overnight, working from home offices became the norm for millions of people. Internet-based meeting apps like Zoom and others have become necessities people use daily. Despite the end of the pandemic, many people are still working remotely, or it is a more significant part of their job than before.

However, another critical technology was also in the works. In 2019, SpaceX began launching its satellite constellation into orbit. Starlink is a network of small, inexpensive satellites that interact with ground-based transceivers, and is intended to provide internet service to most of the world. As of early 2024, 6,000 satellites served three million Starlink subscribers. The company plans to double the number of satellites to 12,000 and ultimately increase it to more than 30,000.

Satellite internet would provide my Montana getaway with phone service, internet access, and WiFi calling, but first, I had to make it work. I installed the transceiver, charge controllers, batteries, and an old 1200 W inverter in a 10-foot-wide storage container so that all the electronics were in one convenient place and easily accessible. I installed several solar panels on the roof, and routed their output to the batteries inside the container. My container is also my remote office, providing an excellent location for video calls, web meetings, and privacy.

I installed everything correctly, but there was a problem. When I powered everything up, the router started complaining, emitting a high-pitched screech. That couldn’t be good, so I started an investigation.

Guessing the power source might be the issue, I used a power analyzer to find the issue. My 1200 W inverter converted DC power from the battery system to 120 VAC 60 Hz, so I connected to its voltage output and put an iron core AC current clamp on one of the lines. I immediately saw that the inverter’s AC output was not even close to being a sine wave, and was filled with harmonics that were adversely affecting the router. The old 1200 W inverter was to blame.

The scope view revealed that the old inverter was incompatible with most of today’s electronic devices. It had to be replaced, so I ordered a new inverter that produced a pure sine output. When it arrived, I hooked it up and ran some tests with the power analyzer. The output looked great: the router stopped screeching with the new inverter. My biggest problem was solved.

What is a Microgrid?

Since my valley has no power, I had to create my own. A power grid that is local and independent of the larger power grid is called a microgrid. Another element of microgrids is that they are intelligent. True microgrids can connect to the outside power grid and provide failover operation for continuous 24/7/365 operation. My rooftop solar panel system isn’t a true microgrid in that sense, but it does what I need it to do. After all, I am not powering a whole college campus or a hospital complex. My “microgrid” is engineered to do exactly what I need. My battery system is charged by the solar panels on the roof. The power is fed into an MPPT (Maximum

Power Point Tracking) charge controller that intelligently manages the energy coming from the solar panels and charges the battery system. Charge controllers like this one protect the batteries from overcharging and overdischarging. They use a tracking algorithm to maximize the energy from the panels. A smartphone app allows me to monitor the system.

Conclusion

Engineers are about solving problems. If you give us lemons, we will make lemonade. COVID-19 was terrible, but it opened the door to remote working. The last few years have ushered in impressive advancements in battery technology, green energy, power conversion, power generation, satellite phone and internet access, and more. Leveraging technological advancements is its own reward. What I was able to accomplish was unthinkable only a few years ago. Now, using Starlink, four 100 W solar panels, a few 100 Ah batteries, a 40 A MPPT charge controller, and a pure sine inverter, I have built a “microgrid” capable of running my remote office at minimal expense. This system has allowed me to live and work in the “middle of nowhere”.

Strengthen Your Energy Storage Supply Chain to Avoid Delays and Shortages

Battery shipping delays and supply-chain shortages can shut down your company, hurt your bottom line and reputation, and harm your customers’ operations. This was a key lesson learned during COVID and, more recently, the Baltimore Key Bridge collapse. If you’re powered by or sell batteries, you need a reliable supply chain to keep a tight schedule – or you can’t deliver. And no matter what, you still have fixed labor costs and overhead. The more the battery companies outsource manufacturing and overstretch supply chains, the more vulnerable you are to their delays caused by:

• Global shortages of raw materials, finished goods, or truck drivers

• Future pandemics

• Cyberattacks

• Shortages or delays due to political turmoil

• Logistics problems like stuck cargo ships, railroad strikes, or bridge failures

The good news is you can avoid most shipping delays and shortages.

Shorter supply chains + recycling = greater reliability

Companies with shorter distances between raw materials, suppliers, and manufacturers, as well as more centralized production, are better positioned to ensure reliable production and shipping. Of course, there’s nothing inherently wrong with global supply chains as long as manufacturers guarantee quality standards and reliable shipping – and make good on those promises.

Unfortunately, as 2020 and 2021 taught us, there’s a lot outside of our control; distance and borders can be a liability and a bottleneck. If your battery company depends on global supply chains for most raw materials and manufacturing, you’re vulnerable to tariffs, shutdowns, shipping delays, infrastructure failures, and parts shortages. A good first step is domestically sourcing more recycled and recyclable materials. This reduces artisanal and new mining, and simplifies supply chains.

Does your manufacturer store backup materials on-site?

Cheap supply chains can cost a small fortune

If your battery manufacturer squeezes every penny out of customers, suppliers, and distributors, then service, flexibility, and reliability will suffer. Look for manufacturers with extensive distribution centers, subsidiaries, or distribution in your region. These add redundancy, shorten supply chains, and reduce your risk. Also, ask whether your manufacturer offers drop-shipping directly to your place of business or installation sites. Finally, be sure your battery manufacturer partners with reliable suppliers and shipping companies – with consistent delivery dates and strong communication.

Smart production and delivery planning save headaches

Between supply chain disruption, e-commerce, labor shortages, and other problems, manufacturers that once had predictable and stable supply chains are struggling to find their footing.

Your battery company must have well-thought-out answers to these questions:

• Which models will we produce, and in what quantities?

• Will we get the raw materials we need, or components shipped to us?

• Will we get orders? If so, when?

• Do we have the proper staffing and equipment to fill those orders?

• Can they be shipped to the buyer or distributor in a reasonable amount of time?

Also make sure your battery company uses enterprise resource planning (ERP) software to monitor inventory, supply chain, forecasting, sales, and deliveries. If their computer system connects everything together, the chances of shortages, production delays, or orders falling through the cracks all but disappear – and that’s good for your supply chain.

Process crucial raw materials on-site

“A vast recycling supply chain collects, stores, transports, recycles, and re-introduces more than 99% of lead back into the lead-acid battery supply chain.”

– US Department of Energy

Just In Time (JIT) is wonderful when supply chains run smoothly. But if your battery manufacturer uses JIT, you’re just one supply chain hiccup away from late shipments or canceled orders.

For instance, recyclable lead batteries require metal grids to hold energy-storing material. Some manufacturers order these grids from other countries. Any delay, from suppliers to shipping, means the manufacturer can’t finish assembly or shipping your batteries on time.

Look for companies that source 100 percent domestic critical materials, and ensure 30 to 60 days of backup supplies on-hand. Otherwise, you could be waiting on delayed ocean freight, trucks, or suppliers thousands of miles away.

The more your battery manufacturer relies on third parties to process crucial raw materials, the more links in your supply chain. For instance, recyclable lead oxide is critical for flooded lead-acid and AGM batteries because it stores energy. On-site oxide storage silos, along with oxide mills that produce refined materials, isn’t reliant on ontime deliveries of raw, recyclable lead, or shipments from a third-party oxide mill. In addition, real-time oxide testing removes the possibility of off-quality shipments that would otherwise delay production.

In-house battery manufacturing shortens supply chains, and ensures that every product uses the same materials, assembly techniques, equipment, skilled workforce, and quality standards. The result? You can expect your batteries to last longer, perform better, and get delivered on time.

Here’s what to look for:

• One location or country for all battery manufacturing

Ideally, this should be an ISO 9001:2015-certified manufacturing plant.

• Durable materials and construction

Look for companies that invest in engineering and raw materials to improve reliability. For instance, thicker battery plates (metal grids filled with energystoring chemicals) provide more chemical energy storage. More chemical energy provides more chemical reactions for longer battery life.

• Robotic assembly with help from trained technicians

This maximizes performance, longevity, and consistency.

7 Supply Chain Questions to Ask Your Battery Supplier:

No company is immune to global supply chain problems. These questions help protect you against common issues and speed up deliveries:

“Do you manufacture all your batteries domestically?” If not, where do you manufacture them?

“Do you source 100% domestic materials for critical parts?” If not, how far - and how many bordersaway do they come from?

“How many days of raw material do you keep on-hand as a backup?”

“Do you source previously recycled materials – for a shorter supply chain and lower environmental impact?”

“What health and safety practices do you have in place to protect employees and operations?”

“How long have you been in continuous operation?”

“Have you filed for bankruptcy?” If so, how many times?

Stringent

quality controls improve product reliability

The best supply chain in the world doesn’t matter if your batteries are unreliable. Make sure your battery manufacturer’s Quality Control includes:

1. On-site manufacturing and quality assurance to spot and fix problems earlier than overseas or outsourced manufacturing

2. Extensive quality checks, including using AI-driven aerospace vision systems

3. Direct testing of batteries from production lines –not cherry-picked models from the engineering lab

4. Chemical/Titration analysis for chemical compound ratios

5. Autopsies and diagnostics of test batteries

6. Measurement with reference electrodes to study positive and negative electrodes

7. Random inspection by scanning electron microscope (SEM)

Supply chains affect end-oflife disposal/recycling costs and complexity

According to the US EPA, lead-acid and AGM batteries are 99 percent recycled and 99 percent recyclable – more than aluminum cans.1 Meanwhile, 19 out of every 20 lithium-ion batteries go directly to the trash.2

In Jan./Feb. 2024’s “Stop Landfilling Batteries,” we covered reasons for the Battery Recycling Gap and recommended approaches to reach universal battery

recycling. What’s relevant here, though, is this: Leadbased battery recycling is widespread and often free – or even profitable for you. Not all batteries are recyclable or free to dispose of, so make sure you plan accordingly.

Conclusion

Now that you know the keys to a stronger energy storage supply chain, you can compare battery manufacturers and ensure you get reliable deliveries with fewer hassles.

On-site Alternatives to Lithium Batteries are Crucial to the Future of Renewables

As renewable energy increases across the country, demand is growing for energy storage solutions to maximize the potential of clean power sources. While energy from solar and wind is greener than that from fossil fuels, it is not constantly available. Even in California, where renewables make up 54 percent of total electricity generated in the state, the power grid remains stressed, struggling to produce enough energy – especially at night, in the early morning, and late afternoon. These are times when clean energy either cannot be generated, or cannot be generated in large quantities.

This makes storage essential, and that energy storage market is growing rapidly. Storage at the utility level uses mainly lithium ion batteries, but there is also a need for storage on the consumer and end-user level. This is especially important as energy stored on-site by those who will use it does not require the utility company to invest in additional infrastructure. But lithium-ion batteries cannot be used in commercial buildings, industrial facilities, and other closed spaces due to safety concerns. This means that, particularly for commercial buildings, alternative solutions, including thermal storage methods, must increase to meet rising market needs and climate goals.

On-site thermal storage solutions that buildings and other large facilities can control themselves will play an incredibly important role. These solutions – which are based on cooling and heating a medium, typically water – are often safer, offer significant financial benefits (especially with new government incentive), and allow buildings to rely more on renewable energy, helping to meet the ESG targets and requirements. Thermal and geothermal solutions based on freezing and unfreezing ice provide a valuable alternative, and are essential in helping the commercial building sector reduce its carbon footprint. About 37 percent of all global carbon emissions come from commercial buildings.

In a growing number of markets, electricity prices vary throughout the day (depending on the source of the power and demand) making on-site storage a valuable money-saving tool. For example, states like California have ample solar energy during

daytime hours, then switch over to fossil-fuel-based power generation at night, in the early morning, evening, and on cloudy days. The difference in cost varies because solar energy costs much less to generate than natural-gas or coal-based power. In response, buildings with energy storage systems can capture regular electricity during the hours when it is cheaper, and then tap this stored energy during hours when electricity is more expensive. This process reduces their reliance on the utility company during high-cost hours.

Such systems do not require buildings to cut their overall power use, allowing HVAC, machinery, and any other equipment and infrastructure to function as needed. Rather, the storage systems allow buildings to simply control and shift the hours when they draw on grid electricity, resulting in lower bills for the same amount of power. Since the Inflation Reduction Act went into effect in 2023, there are significant government and tax incentives for such systems, and storage solutions often do not require full upfront payment.

In addition to financial savings, onsite thermal storage solutions help increase reliance on renewables, and reduce carbon emissions. When these systems are charged during hours when most electricity is coming from renewable sources, the power is not only cheaper but greener. In addition, being able to discharge this power during the more expensive hours (when power is often based on fossil fuels) cuts down on buildings’ contributions to carbon emissions. This is especially important in states that rely on peaker plants, or fossil-fuel based plants that only come online as needed when renewables are not available. These peaker plants are often more polluting than fossil-fuel plants that run around the clock.

Such systems allow buildings to meet power demands amid increasing regulatory pressure to

reduce carbon output. For example, a recentlypassed law requires federal buildings across the country to work toward net-zero emissions by 2045. In New York city, legal regulations also require buildings (the city’s single-largest source of greenhouse gas emissions) to reduce their emissions by 40 percent by 2030. In addition to helping buildings comply with a growing number of measures like these across the country, on-site thermal energy storage systems help buildings and their tenants improve their overall sustainability profile, something increasingly important to consumers.

The use of on-site storage systems also allows buildings to help reduce pressure on the electric grid at peak hours. Relying on stored energy during these high-demand hours means that more power is available for others, helping to reduce the risk of blackouts or brownouts – the latter of which more utility companies say they could be forced to implement if nothing changes and electricity demand continues to grow.

In such an environment, it is clear that thermal energy storage systems will play a larger role, especially for commercial buildings. In general, these types of systems are a central component to creating the dynamic storage market that is needed to allow renewable energy to truly be the transformation force the planet so desperately needs.

Planning BESS Projects?

Use predictive analysis to prove out profitability

Accurate economic analysis and foresight are critical to the success of energy transformation projects, where the full impact of decisions made today may not be seen for years. New and rapidly maturing battery energy storage systems (BESS) –tapping into a diversity of chemistries and technologies – offer attractive paths forward for achieving more reliable, more sustainable, and more profitable energy investments. Stakeholders, including utilities, developers, integrators, and regulators, all have incentives to put new BESS strategies to the test to determine which can best contribute to an energy infrastructure that’s more stable, resilient, and adaptable to long-term demands.

Analysis of any specific energy project must go beyond simply measuring the cost and performance of a particular BESS in isolation. Each project’s holistic mix of site location, BESS technology, and market application can produce unique results; getting even two out of three right doesn’t guarantee success. Investments cannot be justified or optimized without rigorous study and planning that anticipates future challenges and prepares to meet them.

Answer the right questions with the right tools

Confidently eliminating blind spots across the lifespan of a project’s specific distributed energy resources, energy storage, and any microgrids is requisite to gauge financial viability. Given the stakes, no part of these decades-long commitments should be left to chance. Long before turning over the first shovel of dirt on a BESS project, leaders must know with a high degree of certainty whether they’re digging a financial grave or are on a path to profit. While a BESS technology congruent with the project’s profitability is essential, an accurate evaluation will be the product of anticipating grid demand, customer preferences, and other market perspectives (all in conjunction with the BESS’s own output).

Project-level analysis produced by appropriately powerful tools will offer predictions that should then shape optimized strategies. These strategies should curb operational costs, boost reliability, limit asset upgrade expenses, and capitalize on wholesale market opportunities. They should also include detailed hour-by-hour planning, driven by cost-benefit analyses to maximize utilization of distributed energy resources.

In order to offer an accurate assessment of a project’s financial potential, analyzed strategies must also carefully account for every IRA incentive, tax break, and financing detail. With that complete analysis in front of them, stakeholders can then make a cleareyed decision as to whether a particular project is financially viable, will remain so over its lifetime, and can offer better returns versus other opportunities.

An example project-level BESS analysis

Project stakeholders can tap free and open source tools to perform this project-level analysis, such as the Electric Power Research Institute’s (EPRI) DER-VET tool that clarifies the long-term strengths and weaknesses of particular distributed energy resources from a technical perspective. Solutions like DER-VET can accurately assess the long-term impact of choosing a particular BESS, accounting for energy storage, PV systems, and controllable loads. They can factor in variables such as project site weather data, electricity and gas tariffs, electrical thermal loads, and time-of-use rates. Analysis should also anticipate limitations imposed by their distributed energy resources, as well as battery cycling limits, power import/export caps, and battery grid charging caps.

EPRI recently conducted a sample analysis comparing potential stationary storage applications using lithium-ion and NiH2 battery technologies. This analysis modeled net present value (NPV) for each BESS option using the aforementioned open-source DER-VET tool.

As battery technologies for grid use cases, lithium-ion and NiH2 offer an interesting set of comparisons and contrasts. Each is an inverter-based resource, capable of quick and efficient energy delivery. That said, their profiles differ significantly in measures of lifespan, overcharge/discharge/deepcycle flexibility, charge/discharge range, fire and thermal runaway risk, acceptable operation temperatures, and overall operating and maintenance costs.

EPRI’s analysis selected a range of scenarios to simulate for each technology, looking at BESS configurations across two-hour, four-hour, six-hour, and eighthour durations, in both Texas’s ERCOT and California’s CAISO energy and ancillary service markets.

Analysis focused on energy timeshifting and frequency regulation revenue streams. For both technologies in both markets, energy time-shifting delivered a similar slightly positive NPV. NiH2 won when it came to frequency regulation, however, earning a much better NPV in both markets and at every duration. Specifically, NiH2 hit an NPV of $2500-3000/kW in the CAISO market,

where lithium-ion languished in the low hundreds per KW. NiH2 reached an NPV of $3000-4000/kW in the ERCOT market, versus $500-700/kW for lithium-ion. Why? The analysis reveals the answer: NiH2 batteries last longer. Lithium-ion offers 3,500 cycles at 100 percent DoD, whereas a NiH2 BESS can complete 30,000 cycles at 100 percent depth of discharge (DoD), thereby collecting more revenue – as the stark difference in regulation services earnings makes clear. This type of analysis is essential to making accurate financial decisions around these technologies, yet would remain invisible without this depth of consideration.

Look before you leap The above example demonstrates the importance of conducting careful predictive analysis versus rolling the dice on major energy infrastructure transformation investments. Once stakeholders commit to a project location, BESS technology, and market strategy, those decisions need to be unequivocally right. Achieving accurate foresight makes all the difference between failed projects, and those that deliver predictable profits for decades to come.

Ensuring Reliability in Energy Storage

The importance of advanced temperature control

Energy storage is a critical component of the renewable energy sector, playing a crucial role in balancing supply and demand, enhancing grid stability, and facilitating the integration of renewable energy sources like solar and wind into the power grid. The most common batteries used in energy storage are Lithium-ion batteries. However, with demand for lithium-ion batteries projected to grow 30 percent annually through 2030, concerns of fire risk related to their widespread use have emerged. The key to addressing these fire concerns lies in the innovation of thermal management solutions and strategies that can enhance the safety and efficiency of these energy storage systems. With a near-future so heavily reliant on energy storage, this innovation in thermal management has never been more important.

Fire risks

Lithium-ion batteries are preferred for their high energy density and efficiency, but they are also prone to such fire risks as Thermal Runaway, a process accelerated by increased temperature, in turn releasing energy that further increases the temperature, leading to an exponential rise in temperature and potential fire or explosion. This can be initiated by overcharging, physical damage, or manufacturing defects in the energy-storage systems. Another risk involves Internal Short Circuits, those defects or damage within the battery that can lead to excessive heat generation and potential fires. External Factors also play a role in associated fire risks; a poorly designed system, inadequate cooling, or environmental stressors (e.g., high ambient temperatures over an extended period) can exacerbate these issues.

A preventive approach

A properly engineered thermal management system should enhance energy efficiency and keep the energy storage system clean and operational, mitigating the risk of potential fires. From the frigid conditions of Alaska to the sweltering heat of the Sahara, properly maintaining the temperatures inside an energy storage system is critical.

In many cases, Battery Energy Storage Systems (BESS) are containerized systems compromised of batteries and electronics which need to be cooled. Typically, thermal management will directly cool the primary components (>80 percent of the heat load), and conditioned air will indirectly cool the secondary components. The heat loads and temperature-control requirements often necessitate at least some direct cooling, but this approach utilizing indirect cooling simplifies the design greatly by eliminating the need to contact all components.

• Chillers:

Chillers, like ECUs, leverage vapor compression technology to provide sub-ambient temperatures. The difference is that the chiller’s compressor cools a liquid which is then deployed to the system for direct cooling. Chillers are typically housed outside the BESS to reject waste heat to the ambient air, and can be ruggedized and scaled to application requirements. The temperature control supplied by these chillers enables the effectiveness of direct-to-component cooling loops as described below.

Technology Options include:

• Environmental Control Units (ECUs): ECUs, or rugged air conditioners, are used significantly in electronics applications such as military edge computing, control systems, and large shelters housing both people and electronics. For secondary components in energy-storage systems, ECUs can provide controlled air temperature to keep all the low-power components at safe operating temperatures. Utilizing vapor compression technology, the air can be tailored to specific temperatures, even cooling below ambient air temperature. This scalable technology has standard capacities ranging from 1 to 12 tons (3.5kW to 42.2kW), which can be modified appropriately for a given system. ECUs are designed to withstand some of the harshest conditions in the world, able to meet salt/fog, dust, debris, and shock/vibration testing requirements.

• Direct Cooling – Single Phase: Pumped liquid loops are often considered for energy storage applications, providing high heat transfer rates and overall cooling capacity. With proper manifolding, it is also possible to achieve relatively consistent temperature across components. In most cases, glycol-water fluids are used; these provide high heat transfer coefficients, but are not ideal in the event of a leak due to their high electrical conductivity. Outside of the chiller, the performance driver is typically the cold plate design,

which provides the thermal link from the fluid to the components. The primary goal is to minimize the size of these cold plates (especially in terms of thickness) to maximize the energy storage capacity of a single container.

• Direct Cooling - Pumped TwoPhase:

Pumped two-phase cooling is similar schematically to singlephase cooling, but it runs at lower flow rates, enabling boiling when in contact with heat sources. This phase change leverages a fluid’s high latent heat of vaporization to provide extremely high heat transfer coefficients. The thermal performance benefits of two-phase flow have been well researched, but there are significant benefits specific to BESS:

1. The use of dielectric fluids. By leveraging the high heat transfer rates of boiling, inferior working fluids can achieve similar performance as their singlephase counterparts. This opens the design space to use dielectric working fluids, creating a significant improvement in safety.

2. Isothermality in a two-phase system, a constant temperature can be maintained across large cold plates or a series of cold plates. This is crucial to maximizing product life and minimizing temperaturerelated degradation. In singlephase systems, waste heat increases fluid temperature so downstream components will naturally have higher temperatures. In two-phase systems, the heat is absorbed, and the quality (liquid-to-vapor ratio) of the fluid is altered.

3. Packaging the two-phase approach uses lower flow rates and smaller pumps, significantly reducing parasitic loads and increasing the BESS’s full-cycle efficiency. This can lead to added redundancy, increasing the service life of smallerform-factor systems. In certain scenarios, you can even reduce cold plate thickness due to improved thermal performance, adding flexibility to rack design. There are many other options to explore, including passive solutions, but the waste heat loads and environments in which these units are housed often lead to a combination of sub-ambient air cooling and active solutions. Further advancements include hybrid systems with eco-mode during cool ambient conditions, which can generate similar performance and reliability but lower operational energy consumption.

Advanced temperature monitoring and control systems

Temperature monitoring and control systems tailored to enhance safety and efficiency are essential to energy-storage systems. These solutions are meticulously designed to tackle the thermal challenges associated with high-density battery configurations, ensuring they perform optimally and last longer. Through the integration of advanced sensors and real-time data analytics, these systems deliver accurate temperature readings and predictive insights, enabling proactive thermal management. This ensures that investments in energy storage are safeguarded, operating safely, and achieving peak efficiency.

How to Choose the Best Energy Storage System for Maximum Profitability

When evaluating BESS options, it's essential to look beyond the sticker price to fully understand the differences between systems to ensure the most profitable and sustainable investment. While some systems might appear less expensive at first glance, they obscure additional costs up-front (which are not included in the quote), and over time (for tools, maintenance and operational downtime). Let’s talk a little about some of the key areas you need to probe in order to make an informed decision that maximizes both cost savings and revenue opportunities.

Uncover hidden up-front and operational cost factors

There is so much more to the story than a low sticker price! To calculate the real levelized cost of usable storage (LCUS), one must consider all required components of the system investment, as well operational costs that can result from systems with lower efficiency and higher maintenance needs, including:

1. Installation complexity and EPC

Less sophisticated BESS often excludes critical components – for example, a fully integrated power conversion system (PCS) – that can translate to huge dollars up-front and over time. Missing components not only add to overall system cost, but also require significant on-site integration, which can lead to compatibility issues and significant delays in addition to higher engineering, procurement, and construction (EPC) costs. Factory-built systems, on the other hand, can eliminate the need for separate assets, reducing EPC costs and installation complexity.

2. Software and controls

Does the system come with a fully integrated energy management system (EMS)? If not, you will be looking at significant integration costs, maintenance headaches, and ongoing licensing and monitoring fees to bring in other external solutions. Be sure to fully understand what is (and isn’t) included, and the cost of implementing/using/maintaining all needed external solutions.

3. Foundation, trenching, and wiring

It is important to probe the site preparation and external infrastructure needs of each system. New fully-integrated systems can minimize onsite work for foundations, trenching, and wiring. They can arrive as ready-to-go building blocks, minimizing on-site work and speeding up the installation process. In rare cases (I know of only one) a system might eliminate the need for BESS auxiliary power infrastructure altogether, which is a huge cost savings, both upfront and over time!

4. Required land

What is the density of each BESS? What external equipment does it require? Advanced BESS with ultra-high-density designs that include everything up to the AC terminals require less space, lowering land acquisition/use costs.

5. Transportation and handling

Evaluate whether the system requires special freight handling, such as overweight permits or expensive lifting equipment. Advanced systems designed for standard intermodal transport can save significant dollars.

Maximize revenue opportunities

To ensure long-term profitability, don’t overlook the following oft-missed factors that can lead to enhanced revenue:

• Usable lifespan and depth of discharge (DoD) Look for a solution that offers 100 percent DoD, allowing all of the capacity to be utilized – both per cycle and over the system's life – and accurate state of charge (SOC), state of health (SOH), and balancing, which ensures the system is always ready for dispatch.

• Warranty and financial security

Review the included and extended warranties carefully! Some warranties cover performance guarantees and maintenance, minimizing financial risks for unforeseen issues.

• Commissioning and deployment time

Systems designed for faster installation and commissioning can begin generating revenue sooner. Look for BESS that can be commissioned in hours or days, compared to the months needed for traditional legacy systems. Time to revenue is key!

• Round-trip efficiency (RTE)

Higher RTE means less energy is lost during the storage/discharge cycle, lowering operational costs and improving profitability. Quantify these efficiency gains to illustrate benefits of one system over another. Don’t believe spec sheets for this one! Look for true test results of the efficiency of the complete system. Some products will limit their stated RTE numbers to battery cells only, which obscures the true efficiency of the BESS that must account also for all the support systems around the cells.

• Operational reliability

Features such as redundancy, comprehensive monitoring systems, and robust support infrastructure minimize downtime. Proactive maintenance through data-

driven insights prevents failures and reduces associated costs.

• Safety features

Built-in safety mechanisms in some BESS reduce risks by effectively sequestering thermal runaway incidents at the single cell-level. This minimizes propagation risk and can lower insurance costs while enhancing operational security.

Make an informed decision

When comparing BESS options, a sideby-side evaluation of all-in-one solutions versus traditional systems might just reveal substantial benefits of all-in-one factory-installed and -tested systems, like:

Dž Significant savings: For things like reduced installation time, lower integration costs and minimized land requirements.

Dž Enhanced revenue opportunities: Through faster deployment, better utilization of capacity, and higher operational efficiency.

Dž Long-term profitability: With comprehensive warranties, extended lifespans, and robust features that ensure sustained performance and financial security. By quantifying these benefits, stakeholders can make informed decisions that ensure the long-term profitability and sustainability of their energy storage investments. So, the next time you’re in the market for a BESS, remember to look beyond the price on the page and evaluate the comprehensive costs/advantages of each solution. It’s likely you’ll find that investing in a fully engineered, factoryinstalled and tested system is not just a smart choice – it’s the key to maximizing your investment’s potential.

According to Climate.gov, 2023 was a historic year for unprecedented and costly damage caused by natural disasters. In fact, the U.S. experienced 28 weather and climate disasters that each cost at least 1 billion dollars. In addition, in the US alone, the likelihood of a power outage due to extreme weather has doubled over the last two decades. And at a global scale, increasingly severe weather coupled with aging grid infrastructure is exposing us to a higher risk of energy blackouts.

In a world where climate events are becoming even more serious and unpredictable, one thing is certain – there are innovative ways to protect cities and businesses from power disruptions, and increase reliability during extreme weather. With heatwaves, floods, and storms causing major main grid issues, and with growing frequency, it is becoming more important to boost on-site energy resiliency and mitigate disruption to businesses.

Microgrids offer significant advantages in maintaining reliability during extreme weather events. Investing in microgrids is a strategic decision that empowers businesses

and communities to ensure uninterrupted power supply and defend critical operations.

Unlike the traditional grid, microgrids can disconnect themselves from the main power source to operate independently during outages. This islanding functionality ensures continued power supply, even when the broader grid experiences disruptions due to extreme weather. In addition, microgrids can incorporate on-site renewable energy sources and battery storage along with onsite backup generators, providing a local source of power during outages. This ensures a seamless transition to a reliable power source during extended outages due to severe weather.

How can we better manage unpredictable weather when it comes to grid uptime? There are several methods and solutions that can work together to maximize operational control and optimize the renewable energy produced on-site (as well as energy used from the grid, when needed).

In order to stay ahead of extreme climate events, companies need to dynamically control on-site energy resources and loads to augment a business or facility’s performance. AI-powered software seamlessly connects to distributed energy resources to automatically forecast and decide the best way and time to consume, produce, and store energy. This will be key to understanding real-time savings, earnings, and CO2 emissions data.

Let’s dive into this concept within the context of an individual building. With AIpowered software, facilities can now be fully prepared for the worst of extreme weather events better than ever before. Software with advanced decision making can monitor a facility’s energy data 24/7; marrying this data with utility grade information from the US weather service, companies have visibility and insights to predict major storms.

This integrated weather data helps a business decide when to switch the system to a storm hardening mode to protect operations. With the concept of storm hardening and islanding, companies are able to prepare a facility or site for islanding, or potentially pre-islanding the site before a utility grid outage.

How does the latest technology accomplish this? AI-powered software is able to use predictive analytics to carefully balance electricity consumption and generation to increase resiliency. It ingests historical data, weather forecasts, energy market pricing, and scheduled operations such as production or building occupancy, to optimize energy flows in case of grid outages. If a storm is on its way, the energy storage is topped off, and non-critical site functions are shut down to minimize impact to operations in case of a blackout.

A case study for preparedness

Let’s look at an example of this in the real world. 2022 left millions of Europeans facing power outages from freezing temperatures, combined with an already strained energy market. Amid these challenges, a property developer for a shopping center near Helsinki, Finland,

decided it was time to safeguard the facilities from a potential energy crisis to prevent downtime, and ensure businesses could remain functional.

The property developer decided to implement an end-to-end solution of integrated energy generation, storage, and management into a microgrid. With the help of advanced software, the owners also gained access to AI-powered automated decision-making, enabling them to best balance the use of storage, onsite renewable power, and grid power depending on pricing, weather forecasts, and other variables. As a result, the shopping center is more resilient to power outages, and also helps to ease grid overconsumption by finding the best times to sell electricity to the grid.

Because the AI-enabled advanced software is looking at weather forecasts, and doing a very complex set of calculations to determine when it’s most useful to sell energy back to the grid, the shopping facility is able to both island itself before a major storm and sell energy back to the major grid at the most opportune time – making it a win-win. This combination of solutions kept the lights on during the winter. It also cut 335 metric tons of CO2 emissions per year, contributed to a 14 percent reduction in annual energy costs, and added Є129,000 in annual revenues from building-togrid sales. This is a fantastic example of how facilities can both safeguard against storms, save (and make) money on energy, and, most importantly, accelerate decarbonization globally.

A final word

In the face of more frequent and severe weather events, creating new solutions to ensure uninterrupted power supply and mitigate the impact of extreme weather on critical operations has never been more important. Implementing microgrids will be a key strategy to consider moving forward, offering the ability to disconnect from the main grid during outages and operate autonomously, bolstered by on-site renewable energy sources and advanced software-driven management systems. By harnessing predictive analytics and AI-powered decision-making, businesses and communities can optimize energy usage, enhance grid uptime, and fortify resilience against storms. As we navigate the challenges of climate change, embracing innovative solutions for microgrids will be one of the best ways we can adapt to our changing world.

The A6983 converters offer flexible design choices, comprising six non-isolated stepdown converters in low-consumption and low-noise configurations and the A6983I isolated buck converter. With compensation circuitry on-chip, these integrated monolithic devices need minimal external components including filtering, feedback, and a transformer with the A6983I. The non-isolated A6983 converters can supply up to 3A load current and achieve 88% typical efficiency at full load. The low-consumption A6983C variants are optimized for light-load operation, with high efficiency and low output ripple, to minimize drain on the vehicle battery in applications that remain active when parked. The low-noise A6983N variants operate with constant switching frequency and minimize output ripple across the load range for optimum performance in applications such as audiosystem power supplies. Both types offer a choice of 3.3V, 5.0V, and adjustable output voltage from 0.85V to VIN. The A6983I is a 10W iso-buck converter with primary-side regulation that eliminates the need for an optocoupler. This converter allows accurate adjustment of the primary output voltage and the transformer turns ratio determines the secondary voltage. All isolated and non-isolated variants have a low quiescent operating current of 25µA and a powersaving shutdown mode that draws less than 2µA. The input-voltage range from 3.5V to 38V, and load-dump tolerance up to 40V, prevent disruption due to transients on the main supply bus. There is also output overvoltage protection, thermal protection, and internal soft start. In addition, optional spread-spectrum operation helps lower electromagnetic interference (EMI) for noise-sensitive applications, and a power-good pin that enables power sequencing. The A6983I and A6983 allow synchronization to an external clock.

High efficiency atomic battery

With strong support from the U.S. Department of Defense, Infinity Power in San Diego County in California has successfully developed an efficient and long-lasting atomic cell harvesting decay energy from radioisotopes. About 62% of total efficiency is achieved which represents a high level of efficiency attained for radioisotope energy conversion technologies. The innovative electrochemical energy conversion from radioisotope dissolved electrolytes forms the core of Infinity Power's technology, in which a liquid form of radioisotopes creates a wide, effective channel for the collection of electrons, which leads to a high conversion efficiency. Advanced packaging designs are also being developed to ensure ample shielding and no leakage. This tiny coin-cell-style device can generate tens of milliwatts of power for many decades by tweaking key design parameters. Furthermore, this technology's scalability allows for a broad power generation spectrum, spanning from nanowatts to kilowatts or more. Its efficiency also means that it can produce more power using less radioisotope, and it has a wide range of radioisotope selection.

Stabilize the grid with dependable and precise accuracy

Virtual Peaker has launched the Topline Demand Control solution for utilities. The technology maximizes the potential of distributed energy resources (DERs), ensuring they can effectively provide grid stability, when required, with dependable and precise accuracy. Topline Demand Control allows utilities to specify and harness an exact amount of demand during a precise period of time while optimizing around device, customer, and program constraints. While traditional virtual power plants (VPPs) manage DERs collectively, Topline Demand Control improves DER aggregation by optimizing device outputs to achieve an operatorspecified load shape. This guarantees precise and predictable load shaping, shifting the paradigm in flexible load management with its ability to provide a variable topline power output, resembling a supply block to grid operators. This solution utilizes AI and machine learning to leverage and optimize control over DERs, starting with batteries and, in the coming months, adding other smart devices like thermostats and EVs to accurately account for total available DER capacity, remove DER event calling uncertainty, reliably manage DERs at scale, and save costs, stack value, and defer system upgrades.

Maximize revenue and ROI

UL Solutions unveiled the new 1.10 version of HOMER Grid modeling software, developed to assist with speeding up and simplifying designing and optimizing renewable distributed energy-plus-storage powered electric vehicle (EV) charging stations, which may allow for the maximizing of their potential revenue and return-oninvestment (ROI). HOMER Grid 1.10 enables users to rapidly calculate potential EV charging revenue based on user-defined charging prices and the costs of supplying electricity from the grid or using on-site renewable generation and storage. These new features join HOMER Grid’s modeling of on-demand fast charging and managed or deferrable smart mode charging when time-of-use energy rates are lowest. The software enables project developers to reduce the time and uncertainty of evaluating the ROI of a proposed, site-specific, renewable energy-plus-storage powered charging station, maximize the project’s value, and demonstrate that value to customers. Modeling results can also help speed the permitting process, reduce the time from quote to construction, and provide cost-savings and revenue generation data that mitigates project risk and may result in better financing terms. Databases for electric loads, utility tariffs, incentives, demand response programs, solar irradiance, and other weather data are integrated into HOMER Grid, allowing developers to analyze the feasibility of a prospective location and powering system configuration and compare multiple sites quickly. Other updates to HOMER Grid 1.10 include the addition of California’s Net Energy Metering (NEM) 3.0 tariffs. Additionally, HOMER Grid allows users to import project production data from other design software. A new enhancement enables users to import multiple data files, from multiple solar photovoltaic (PV) arrays, for example, to be combined into a single energy modeling project in HOMER Grid 1.10. With recently updated utility tariffs, HOMER Grid software integrates more than 90% of tariffs from the United States (U.S.), Mexico, and Canada. The software also allows the creation of custom tariffs, enabling more accurate modeling of energy project costs as utility pricing continues to evolve.

Maximizing Energy Storage Profitability

Getting on the right foot

for BESS project success

Energy storage is on the brink of yet another record-breaking year. Despite kinks in the supply chain from tariffs or interconnection issues, growth continues to escalate across the US energy storage market. After enjoying 100% growth between 2022 and 2023, analysts say the market could see 45% growth in 2024. Battery energy storage system (BESS) growth is outpacing wind and solar as utilities balance renewables with grid resiliency. For utilities planning BESS capacity additions, finding the right EPC and O&M partner is key to a successful project. Three considerations stand out as utilities explore their options:

I. RELIABILITY IN YOUR PARTNERS

Reliability extends well beyond components. Success requires getting the right stack of partners on your side to design, source, build, and maintain highperforming BESS. Energy storage contends with rapidly evolving technology, safety codes, permitting standards, and other risks. Partnering with a singlesource, technology-agnostic partner ensures your team has visibility into — and can proactively address — changing dynamics and project pitfalls, including:

• Changing technology - Battery hardware components make up a large portion of system cost. With BESS technology seeing updates every 6 months, it’s critical to stay ahead of technology trends, understand product gaps and functionality, and optimize how to apply them.

• Accountability - Managing complex variables such as on-time delivery, gaps in product functionality, or scope issues between various providers creates complexity best handled by an experienced, singular partner.

• Regulatory understanding - Evolving safety standards result in noncompliance risks. Your EPC partner must demonstrate a deep knowledge of safety codes and an enthusiastic engagement with AHJs, early and often is always best.

• Procurement risks - Look for a partner that can leverage a deep supply network to ensure on-time delivery while maintaining flexibility in the face of logistical risks, as well as experience traversing the never-ending contemplation of tariff risk.

II. FUTURE-PROOFING AUGMENTATION

Batteries degrade over time. Acknowledging that the only constant is change itself makes planning for the future more art than science. SCADA integration, energy density, and drastic storage medium technology shifts are all ripe for changes in the coming years. Future-proof your BESS augmentation to ensure a smooth transition to next-generation technology advantages and grid integration through:

• Designing with flexibility in mind.

• Steering clear of proprietary energy management systems designed for today’s technology.

• Keeping future augmentation in mind with your balance-of-plant design. Consider tactics like flexible tie-in points that allow for feeder level augmentation or expand your BESS with a medium-voltage design that won’t require a complete overwork of the existing substation.

• Ensuring adequate access for maintenance is often overlooked but is critical for augmentation and service.

III. BALANCING RISK, COST, AND REASON

Energy storage can pose risks and asset owners need measures to manage them. Some utilities may try to cover their BESS assets with a cookie-cutter approach that can either fall short or overspend needlessly.

With fire safety, for example — do sprinkler or suppression systems provide the most value in

remote, uninhabited areas? Other design or productlevel features provide more bang for your buck while also not introducing additional points of failure.

Future-proofing schemes, like large arrays of spare conduits, can be a waste of capital if not strategically placed.

Ultimately, what works for one site will not make sense for another. With in-house engineering capabilities, DEPCOM Power customizes each system, treating the design as if it will own the plant itself. We assess each unique project to deliver smart designs that are verified with results based on our extensive experience.

DEPCOM’S ONE-SOURCE PARTNERSHIP

Looking across the full lifecycle, DEPCOM delivers on every aspect – from expert design and engineering to strategic sourcing, construction rigor, and long-term service agreements. Our guiding focus is to maximize BESS profitability while carefully managing associated risks.

Our partnership approach goes well beyond what you may expect from an EPC. Few conduct thorough onsite visits to quality check overseas battery suppliers, or partner with BOP OEMs to customize electrical enclosures. Even fewer offer our unique bankability, a result of being backed by Koch Industries, the second largest privately held company in the country.

Whether you are a utility just entering the BESS ecosystem or an experienced asset owner, DEPCOM’s one-source partnership delivers a turnkey experience anchored in market-leading value and support.

About the Authors: John Zetterstrom serves as DEPCOM’s VP of Business Development working to provide quality EPC services to developers, IPPs, and utilities.

Hydrogen Horizon

The rising star in sustainable power

The renewable energy landscape is changing rapidly. Advances in technology are powering a green energy renaissance in general, and many alternative power sources are being enhanced, developed, and promoted. These breakthroughs can be anticipated to have major consequences and implications that promise to disrupt whole companies and industries.

Hydrogen, in particular, is emerging as a rising star.

Hydrogen as an energy source

The idea of using hydrogen power arguably dates back to 1838, when a chemist from Switzerland, Christian Friedrich Schoenbein, made the first fuel cell by adding hydrogen gas to oxygen to create electricity. Today, multiple industries use this renewable energy source in various ways, and have done so for years because it offers many advantages over other energy sources.

Most importantly, when hydrogen is used as fuel, it emits no greenhouse gases. Hydrogen fuel cells only produce harmless water vapor and heat as byproducts. In addition, unlike many other renewable energy sources, hydrogen can be stored and transported safely.

Hydrogen also offers a higher energy-to-weight ratio than traditional gasoline and other fossil fuels. Bountiful and efficient, it is becoming an increasingly practical choice for many different use cases – even for those in heavy industry and throughout the supply chain.

Another important advantage of hydrogen is that the techniques for producing it as fuel are eco-friendly. For instance, hydrogen can be generated using water electrolysis and biogas. There’s even a way to derive hydrogen from municipal solid waste, meaning environmental advocates need not worry about the emergence of a new carbonproducing monster. In addition, as hydrogen production scales up, these renewable industries will also grow.

Two major challenges currently stand in the way of hydrogen’s widespread adoption as an alternative source of energy: First and foremost is fear – a difficult bridge to cross. Second is the current lack of necessary infrastructure.

Overcoming fears

Hydrogen tends to be associated with disaster in the collective imagination due to the Hindenburg accident, and, in my experience, people are slow to change. Similarly, fears of fire have provoked some communities to agitate against lithium production facilities.

As a result, fear-mongering and rumors threaten to keep us in a reactive posture that would foreclose the possibility of exploiting hydrogen and other sources of renewable energy, despite the fact that they present readily available and streamlined sources of clean power.

Hydrogen has come a long way since the early 20th century, which is why educating the public is key. When people understand how this energy source works and how it can help us move away from fossil fuels, we can have real and proactive discussions about how to best leverage hydrogen to power our future as inhabitants of Earth.

Building new infrastructure

Since the first petrol station was built in 1905, Americans have become so familiar with this fuel that it is ingrained in our society. While there are gas stations all over the U.S., no such infrastructure exists for hydrogen fuel. Meanwhile, most people find change difficult, especially if there are any drawbacks, whether tangible or perceived.

If hydrogen is to go mainstream, there are many large infrastructure elements to consider. How will the fuel be stored? How much will developing the necessary new infrastructure cost? How can clean energy advocates best engage with the public to gain their perspective? How can we forestall the kind of pushback against hydrogen that is currently erupting around lithium alternatives?

Expanding infrastructure to make hydrogen widely accessible is not only feasible but necessary. Governments of various levels, businesses, and organizations should collaborate to invest in a robust network of hydrogen production facilities, distribution systems, and refueling stations to pave the way for widespread adoption.

Combining economic and environmental performance

Fives’ 100% hydrogen duct burner,The Hy-Ductflam is designed for new installations or to replace standard duct burners, and can be easily implemented by manufacturers with very limited process modification. The Hy-Ductflam, enables its customers to easily switch fuels going from 100% natural gas (NG) to 100% hydrogen (H2) without any changes made to the equipment. Providing high efficiency and mechanical reliability, the Hy-Ductflam is suitable for any duct configuration. This mean it can be installed both in new installations and as a replacement of standard duct burners thus limiting costs for manufacturers. This technology is mainly dedicated to drying application in ceramic, minerals, pulp, etc. to name a few but could be extended to other applications such as heat recovery boilers.

A diverse energy landscape

As a promising carbon-neutral solution, hydrogen is positioned to play a major role in the power landscape to come. However, the exact future of hydrogen, lithium, natural gas, biofuels, and other energy sources remains unseen. Right now, so many different options are under development that it is difficult to predict which will emerge as the winner and dominate the energy market.

Indeed, I suspect there won’t be a final winner. Different renewable energy sources have their own particular advantages and disadvantages. In the end, a number of viable renewable energy sources will probably demonstrate their superiority in certain domains. Humanity would be best served by building a diverse energy system that takes advantage of the various strengths of each. Specific options will make sense depending on their particular use cases, as well as their location.

What’s important isn’t to predict which renewable energy will win. Rather, it’s important to focus on the end goal of providing efficient, affordable, clean energy. Everyone has a part to play in the transition away from carbon-producing energy. When a diverse energy map of green innovations replaces the status quo, we all win.
