Information

you stand outside in utter silence, rendered mute in awe of brilliant and sparkling snowcovered mountains rising from pristine water. Blue is everywhere. You find yourself holding your breath and staring all around you, trying to capture the memory of that moment, knowing that what you’re seeing can never be accurately conveyed from a picture.

We don’t belong there. Antarctica is meant only for the whales and penguins and sea birds and krill, and other creatures that thrive in an environment meant for them.

Many conservationists promote the idea that we are all stewards of the environment. Nowhere does that ring truer than when you find yourself a visitor to the last unspoiled frontier. Mere interlopers, we have to maintain painstakingly detailed care and vigilance so as not to introduce any pollutants from our outside world. The Antarctic Treaty has promoted this idea since it entered into force in 1961. Although 12 countries initially signed it in 1959, the treaty currently counts 56 countries among its parties. It’s quite an achievement: “Recognizing that it is in the interest of all mankind that Antarctica shall continue forever to be used exclusively for peaceful purposes and shall not become the scene or object of international discord.”

Can you think of anywhere else on earth where that language would hold water? Granted, it helps that the deeper you go into Antarctica, the less compatible the conditions become for human life. Yet, 29 countries have established 70 permanent research posts around the continent, with the United States staking the absolute south pole.

The International Association of Antarctica Tour Operators (IIATO) began in 1991 as a collaborative effort to rebrand all visitors as environmental ambassadors. It became the ultimate pack-it-in/pack-it-out guide to establish strict protocols throughout the tourism industry to safeguard the south pole region from contamination. Oddly, just being there made me feel like our ship was one giant contaminant. Still, the first time we rounded a bend and saw people standing on a snowy slope, I was outraged. How dare those trespassers ruin our view. (“Pot calling kettle, come in kettle.”) They turned out to be researchers and scientists, which were peppered among various points as we traveled along the Antarctic peninsula. I couldn’t fault them, seeing as how a good portion of our ship’s staff were on board as either resident or visiting researchers, all sharing information with colleagues on other ships and science stations around the world to track the health of the region. Two lanky and seasoned men from California were hitching a ride to count penguins. It seemed like the kind of dream job that you know deep down you could never dedicate your life to doing, but someone has to. This is especially important given the heightened risk of bird flu. Most worrisome to our bird counting friends and their colleagues is the very real possibility of infecting protected

or isolated avian species. Apparently, avian influenza has already killed scores of penguins and threatens many more colonies. Did I care that one of our onboard wildlife experts confidently pegged penguins as possibly one of the dumbest animals on the planet? Or that she half-joked that it was no wonder they were at the very bottom of the Antarctic food chain? No, I did not. All I saw, after the velcro fasteners on our outerwear were carefully inspected for seeds and contaminants, and our knee-high waterproof boots were thoroughly scrubbed and sanitized before climbing into the heavy duty zodiacs that ferried us to the “landing” (where we hopped into 12 inches of water and waded toward the rocky beach), was a bunch of unbelievably adorable, noisy, ungainly, and smelly penguins waddling along their little “highways”, regularly face planting before righting themselves like nothing happened. While I admired the leopard seal we saw earlier that was in a food coma on a blood-stained ice floe, likely after having feasted on one of these little guys, there’s something about penguins that always elicits a collective “Awwww!” It was suddenly clear why no children were allowed on our expedition — the impulse to touch these animals (and everything we saw) was so strong, yet we could only look, and even that had to be at a minimum distance of 5 meters. We were prohibited from placing anything on the ground but the soles of our sterilized boots: no kneeling, no lying down, not even our belongings could make contact with the surface. We were interlopers who posed a lethal risk to these clueless creatures. If there’s one thing we humans do well, it’s pollute. Even with the best intentions, any move we make in the name of discovery or aid, or simply existing, will result in some form of waste. This made the trip seem a little less shiny; the 600 or so departures from Ushuaia this year will carry more than 100,000 tourists to Antarctica. When I asked the chief engineer how much fuel the ship needed, he told me they burn through 85,000 gallons of diesel per trip. What about alternative fuels? “Nah,” he said, “this is a state-of-the-art vessel, we emit minimum noise and disruption to the waters around us. Besides, for now, diesel is the best we got.”

“Penguins mate for life. Which doesn't really surprise me that much, because they all look exactly alike. It's not like they're gonna meet a better-looking penguin one day.”

Protecting the Renewable Grid Against Extreme Weather

by Loggan Purpura

In the last five years, North America has experienced a significant increase in severe weather events that have impacted power grids. In Canada, Alberta's electric system operator issued 17 provincial grid alerts since 2021, due to extreme weather conditions, compared to just four between 2017 and 2020. Similarly, the United States has seen a doubling of power outages tied to severe weather, from about 50 annually in the early 2000s, to over 100 annually on average in recent years. Notably, 2021 saw 20 separate billion-dollar weather and climate-related disasters, including winter storms, wildfires, floods, tornado outbreaks, and tropical cyclones. These events highlight the vulnerability of power systems to climate change related extreme weather, underscoring the need for enhanced grid resilience and reliability.

weatherization, preparations, and inspection for incoming weather events, as well as annual training and record keeping attesting that you have completed the tasks for inspections. Owners should ensure that the operations and maintenance (O&M) providers are prepared to meet the requirements for the region.

Don’t forget the areas often overlooked in an emergency response plan, including hurricane preparedness, water shortage, pandemic and epidemic, and restoration of service, and ensure all site personnel are familiar with and trained on required protocols. While there is often no specified regulatory oversight when sites are being constructed, it is noteworthy to consider putting an emergency preparedness plan in place that meets the regulatory requirements.

Different countries, states, and provinces need to meet local regulatory requirements. Texas facilities, for example, are subject to the Public Utility Commission of Texas, and must have a program that considers the site’s critical components. Critical components are defined as, “Any component of a resource or transmission facility that is susceptible to fail as a result of a weather emergency, the occurrence of which failure is likely to significantly hinder the ability of the resource or transmission facility to function as intended or, for a resource, is likely to lead to a trip, derate of more than five percent of the capacity represented in the resource’s seasonal net maximum sustainable rating or of the

streamlined execution

Traditional power generators typically have one operator/owner compliance department, whereas renewable energy providers may have several involved parties, including owners, EPCs, and operators. Coordination and communication between these parties are key, especially if you are in the commissioning phase or development. The O&M team is eventually going to be taking on any kind of emergency response or weatherization, but they are unlikely to be around in the development stage, so it’s important to have all the information available in a digital platform where they can see the emergency response plan, site details, inventory, and what has been done and where.

Constant weather monitoring is a must. Knowing the timing and direction of an approaching severe weather system is vital to ensure a facility is best protected against the elements while optimizing power generation pre- and post-event. Renewable management platforms can feed weather data right into the operational process so managers can make data-driven decisions at the right time.

Be prepared for inspection

Owners can expect regulators to come on-site for inspection. Some regional regulators are using these visits to learn more about what is applicable to inverter-based resources. First on any regulator’s list

maintenance equipment workflow, see what was done and by whom, as well as comment, review, and approve work orders. This trail can feed directly into a compliance console, allowing stakeholders to see the status of compliance and confirm the absence of reportable incidents with a few clicks.

Being compliant can also help save millions of dollars by reducing damage and ensuring that facilities continue to produce expected power and supply the grid, both during and after severe weather events. Most regulators stress the importance of training, maintenance, and documentation, and want to see evidence that this is being done.

Take stock after the event

The resilience of the power grid against such extreme weather conditions remains a critical concern as climate change continues to exacerbate the severity and frequency of these disasters. It is important to document lessons learned after a significant weather event has occurred. No event will be the same, so recording as much information as possible and having it digitally accessible for historical analysis will help to better prepare for the next event.

Mapping a New Atlas for Offshore Wind

by Mauricio Fragoso and Marie Cathelain

A key challenge in the offshore wind industry is the assessment of the resource, essential throughout the different stages of a development project, from screening of areas of interest, to optimization of wind farm layouts to account for spatial heterogeneities and wake losses.

Floating lidars have been established since 2023, with the University of Maine collaborating on the first deployed unit. This enhances the array of solutions available, extending from core expertise in processing raw satellite observations to numerical modeling of the atmosphere, for the benefits to renewable energy stakeholders seeking integrated options.

Regulated by international standards, methods are usually based on a combination of mesoscale modeling on large areas, and offshore short-term observations at a single location. However, an important level of uncertainty about the actual offshore wind resource remains, particularly in coastal areas where the environmental conditions are complex. Offshore blowing winds, gravity waves, etc., induced by orography effects from the coast and thermal impacts in the land-sea atmospheric transition, result in strong airsea and land-sea interactions. These are known to be challenging conditions to capture (with one or two lidars) and to model, even at high resolution.

Offshore assessment from space

Spaceborne synthetic-aperture radar (SAR) observations can be used to capture complex air-sea and land-sea interactions in off- and near-shore locations.

SAR provides observations of the Earth surface in almost all-weather conditions, night and day, regardless of the cloud cover. Over the ocean, SAR measures the sea surface roughness, i.e., the surface backscattered signal of the centimeter-scale waves related to surface wind stress that react quickly

to air-sea interactions. Other phenomena can sign on the backscattered signal at the sea surface: (i) bright targets (e.g. ships or wind turbines), (ii) marine pollution, rain cells that need special filtering as they are not related to wind, and (iii) atmospheric phenomena in altitude (e.g. convective cells, gravity waves, etc.). Wind farm-induced effects on the atmospheric flow such as single or superposed wakes, far wake, or blockage upstream can also have a signature on the backscattered signal. An example of a standard 1-km resolution surface wind field retrieval from a Sentinel-1A SAR image off the East of England is displayed in Figure 1 (left). Thanks to our enhanced processing algorithms, the SAR signal is cleaned from artefacts and results in the 500-m resolution surface wind field in Figure 1 (right). An additional in-house recalibration is performed based on a machine-learning algorithm trained on 22,000 buoys measurements from the National Data Buoy Center. This leads to a reduced surface wind bias from –0.57m/s to 0.01m/s and a reduced standard deviation from –1.25m/s to 0.85m/s all around the world.

Satellite and in-situ observations, modeling, and machine learning

To address altitudes relevant to offshore wind projects (40m to 300m), a vertical extrapolation of the SAR surface wind is needed. While current international guidelines recommend the use of power or logarithmic law in absence of measurements in altitude, such empirical formulae need to be calibrated, and are not representative of the complex environmental conditions occurring nearshore. The increasing use of high-resolution mesoscale modeling brings some insight, but still lacks accuracy due to physical parametrization, grid resolution of a few kilometers, and filtering of the numerical schemes.

Figure 1: Surface wind speed retrieval from Sentinel-1A SAR observation on 202402-04 with standard processing (no bright target filtering, 1-km resolution, left) and enhanced processing (filtering, 500-m resolution).

In order to alleviate the abovementioned drawbacks of standardized methods, especially in coastal areas or in locations with few measurements, a new product is derived and relies on the complementary synergies between high-resolution satellite observations, in-situ data, and mesoscale modeling. A machine-learning algorithm is trained on ten lidars in the North Sea to learn the relationship between SAR surface wind speed and vertical profiles from in-situ measurements and stability-related features from a mesoscale model. The final outputs are enhanced wind atlases at a 500-m resolution, from a 20-year database of satellite observations and the derivation of Weibull parameters.

The first stage of the product development focused on Europe, with publications of validation work in peer-reviewed scientific journals and SAR-extrapolated wind speeds provided as data to bidders of two calls for tenders (floating and bottom-fixed) in France. The accuracy is less than 3 percent in terms of wind power density, and less than 4 percent in terms of gross annual energy production. An extensive validation has recently been performed against lidar measurements in the US, China, and other locations in Europe. Figure 2 shows the boxplots of absolute bias relative to the mean in-situ wind speed (left), the correlation (R2, middle) and the root-meansquare error (RMSE, right) of the SARextrapolated wind speeds at 100m at six locations in the US, three locations in China, and 19 locations in Europe, from 1km to 102km offshore. For comparison purposes, the performance of opensource high-resolution (2-3km) mesoscale models from research and meteorological centers is displayed (dashed boxplots) alongside the SAR results (plained boxplots). The SARderived extrapolation outperforms the mesoscale models in all areas, especially in the US, with median biases less than 2 percent, correlation higher than 0.92 and RMSE less than 1.35m/s. This shows the ability of the SAR-extrapolation algorithm to deal with a broad range of wind regimes in locations different than in the training dataset.

Conclusion

The 20-year database of SAR observations of the surface wind field at a 500-m resolution over >250km areas from three European satellites (ENVISAT and Sentinel-1A and –1B) is an invaluable source of data for offshore site characterization. Offshore wind atlases are derived over Europe, the US, and in Asia-Pacific. They are available before lidar installation or in complement of measurement

campaigns. Combined with standardized processes, it allows to significantly reduce the cost of assessment of offshore wind projects.

In addition to inflow characterization, SAR observations are also a unique way to observe wind speed deficit by existing wind plants due to blockage or wake effects.

Crisis-Ready Fleet Management

Maximizing resilience through strategic rentals

by Andy DeLaGarza

In the realm of fleet management, the only certainty is uncertainty. From unexpected storms to traversing rough, remote terrains, businesses must be prepared to navigate extreme circumstances with agility and efficiency. Many wind farms are in remote locations spanning a vast, uneven terrain. Projects don’t halt based on unprecedented weather, so having the ability to mobilize resources promptly can mean the difference between smooth operations and costly disruptions. Fleet rentals play a strategic role in enhancing resilience and ensuring readiness when crises strike.

Planning for the unknown

3. Flexibility: Rentals can be easily returned once the job is done, providing businesses with greater flexibility and agility in resource management. Renewable development job lengths vary, as do the types of units needed for specific jobs. Having assets available for the duration of the job allows your crew the opportunity to get work done on time, and return units when they are no longer required or have active use.

4. Quality assurance: By opting for rentals, businesses can access brand-new trucks and trailers with each rental, ensuring optimal performance and reliability. Equipment rental houses do a multipoint inspection of all units before being transported.

Extreme weather events are inevitable, posing significant challenges to businesses reliant on fleet operations. Yet, with proactive planning, organizations can mitigate risks and minimize downtime. Instead of solely investing capital in assets for worst-case scenarios, fleet managers of renewables companies are turning to rental solutions for greater flexibility and cost-effectiveness. By embracing unit rentals, businesses can access niche equipment on-demand when it's needed most.

Tailored for success

When disaster strikes, the demand for specialized equipment substantially increases. Whether it's restoring power in isolated areas or navigating the rough terrain of wind farms, having the right tools on hand is critical for effective response efforts. You may not require these units for day-to-day operations, but in these highstakes scenarios, specialized fleet rentals with custom upfits can pair need with speed and onsite efficiency. When incorporating essential accessories like generators, work lights, front bumpers winches, and fuel tanks, these customized trucks are specifically designed to meet the unique needs of storm recovery operations surrounding power restoration with wind farms. By taking advantage of tailored upfits, fleet managers gain the freedom to adapt units quickly and efficiently, ensuring maximum readiness in the face of adverse conditions.

Benefits of renting

Renting your fleet isn't just a short-term fix—it's a strategic investment in long-term resilience. Here are eleven reasons why businesses should consider fleet rentals in their mix:

1. Affordability: Renting offers a cost-effective alternative to buying, allowing businesses to pay a fixed cost for specific units as needed. If specialized assets are required to cross rough terrain, renting these niche pieces of equipment will save money by allowing organizations to pay a monthly fee rather than purchase the equipment outright.

2. Personalized customization: With rental solutions, customized upfits are installed for you to increase productivity, eliminating the hassle of manual installations. Each renewable project requires different accessories, so fully customizing your fleet rentals with upfits for the job at hand will minimize your downtime while having an optimized fleet. Whether you are selecting the site for the farm, constructing the turbines, or maintaining the windmills, each development phase of a wind farm project requires unique upfits.

5. Damage protection: Wind farm projects can lead to damaged units due to the size and weight of project equipment. Rental providers often offer unit protection plans and preventative maintenance programs, safeguarding businesses against unexpected costs and downtime. These plans help with routine vehicle maintenance and save you on the backend with returning units with damage.

6. Nationwide service network: Rental partnerships provide access to a network of service locations across the country, ensuring timely repairs and support wherever operations may take you.

7. Minimal commitment: Unlike purchasing, renting entails minimal long-term commitment, allowing businesses to scale resources up or down as needed without being tied to capex investment or depreciation. Many rental houses require a 1-month minimum rental agreement. Due to the varying project duration of wind farm development jobs, having a flexible rental agreement creates space to extend the contract length as needed.

8. Environmental sustainability: Fleet rentals offer an eco-friendly option, as they reduce the need for companies to maintain a large fleet of vehicles that may not be consistently utilized. By renting vehicles when necessary and having additional custom units at hand for when a storm strikes, businesses can minimize their carbon footprint.

9. Enhanced scalability: Unexpected weather can strike at any moment. In times of sudden growth or unexpected demands, renting work trucks allows companies to scale their fleet quickly and efficiently without the long lead times associated with purchasing vehicles. This agility enables organizations to capitalize on opportunities without being hindered by outside production limitations.

10. Access to advanced technology: Rental fleets often feature the latest advancements in vehicle technology, such as telematics systems. Businesses can benefit from these innovations when renting without the upfront costs often associated when purchasing units.

11. Improved cash flow: Renting eliminates the need for large upfront investments in fleet assets, preserving capital for other strategic initiatives. Additionally, fixed monthly rental payments provide predictable expenses, making financial planning more streamlined.

In an era defined by uncertainty, the ability to adapt and respond swiftly is paramount for business resilience. By prioritizing fleet preparedness and embracing rental solutions for wind energy project sites, organizations can enhance their ability to weather storms with confidence.

From specialized equipment to nationwide support networks, the benefits of fleet rentals extend far beyond mere convenience. They represent a strategic initiative for businesses seeking to thrive in an unpredictable world. So, when the next storm looms on the horizon, remember to plan, prepare, and prevail with strategic fleet rentals.

Inspecting Inside and Out for Blade Hazards

by Rogers Weed

Image data from visual inspections is nearly always the starting point for planning a blade maintenance campaign. Historically, external visual inspections of the outside of the blades have been the dominant dataset because they are less expensive to collect; no one needs to climb the tower to gather images of the blades. Ground-based cameras were initially employed, which then gave way to drones and automation that increased both the quality of images and the efficiency of collecting those images.

Recently, however, we have seen a significant increase in requests for internal blade inspections, despite the extra cost involved in collection. Why the recent increase? What types of problems does each inspection type detect? How should customers think about using them in managing their fleet?

Internal inspections come in more shapes and sizes because the process already involves sending people up the tower. Some are done entirely manually by having the technician crawl into the blade with a flashlight and a camera. Others involve using manually operated robots (including drones) to assist in data collection. Internal inspections often go beyond visually documenting the inside of the blade, and include tasks like checking the lightning protection system cables and doing tapping or other non-destructive testing on suspicious spots inside the blade.

What problems is each process useful for detecting? Erosion of the leading edge is an easy one, as this problem starts from the outside of the blade and works its way in; an external visual inspection is the obvious choice for identifying these problems. Similarly, lightning strikes generally happen near the tip of the blade where getting an internal view can be nearly impossible. Since the outside of the blade features receptors that can be visually inspected for damage, an external visual inspection is generally the first tool for detecting lightning strikes (a test of the lightning protection system, or LPS, is another valuable diagnostic). Laminate cracks, however, are a crossover problem. While they can be spotted from either an external inspection or an internal one, cracks on the inside can often be detected sooner since the surfaces are not painted, and early laminate stress can be seen in the form of whitish areas.

Internal inspections are where most structural problems will be best assessed. Large stress cracks will show up in the laminate and can corroborate things seen from the outside. Bond line failures around the sheer webs and spar caps, as well as any problems with the root structure (connecting root bolts, etc.) are identified through an internal inspection. The LPS down conductor cable is also accessible from inside the blade, and sometimes there is obvious visual damage related to lightning flash overs from the laminate.

A few final observations before moving to suggestions on using these tools: Most of the structural problems detected from the inside will require expensive repairs, so the earlier they are detected, the better. Problems like laminate cracks are usually visible from the inside before they can be seen on the outside. External inspections can be enhanced using thermal sensing to reveal problems in bond lines, but managing the

heat source is tricky so reliable results can be tough to produce.

How, then, to decide on using these tools? Cost is certainly a major factor – internal inspections can be five times more expensive per wind turbine than external inspections. If the assets are approaching the end of their warranty period, an external inspection can be a cost-effective way to document their condition at transfer. If the blade models on site are known to have structural problems, internal inspections will be much better at detecting those and, as mentioned before, the earlier those are detected the better. If previous external inspections have revealed cracks in the exterior of the blades, those should all be further investigated via internal inspections. Collecting accurate distance-tothe-root information will allow an internal inspection to provide further insight into suspicious cracks seen from the outside.

At the end of the day, what’s most important is adopting a datadriven approach to getting the most from a finite blade maintenance budget. High-quality data consistently collected is the cornerstone of this approach. For visual inspections, image resolution, lighting, and focus, and accurate measurements of defect size and location from the root of the blade can be the difference between a maintenance campaign that accomplishes its objectives on time and budget, and one that rapidly falls behind when repair teams discover something unexpected when they arrive to do their work.

Safeguarding Wind Against Power Outages

by Alberto Barcia

The unprecedented twin challenges of ensuring secure and affordable energy supplies and meeting climate targets have propelled wind power development into an extraordinary new phase of ever-faster growth. After a challenging year, the global wind market is ready to bounce back in 2024. Experts predict that 680 GW of new capacity will be added in the next five years.

Also, the increasing demand for renewable energy has resulted in manufacturers increasing the wind turbine dimensions and capacity, which implies the installation of increasingly larger blades and towers that are significantly more sensitive to adverse weather conditions — posing a greater risk for major component damage. Stresses can be reduced by aligning the rotor to track the incoming wind. During extreme weather conditions, power outages can happen suddenly.

In this regard, the existing power backup solutions are based on a generator with a reciprocating engine (genset). Although the genset machine is capable of starting autonomously and supplying hard loads for a long time, it starts working a few seconds after a failure, exposing the system to costly damage. Summarizing, this technology presents low efficiency, as well as low commitment to sustainability.

In this context, battery-based yaw backup system products are a sustainable solution which ensures an instant response in hazardous weather conditions to reduce the mechanical stresses of the wind turbine through fast feeding of the yaw system, thus keeping the components safe and avoiding financial losses. Furthermore, the battery-based yaw backup system also provides an emergency electric power source to support essential loads such as control, communications, and thermal, among other systems.

The battery-based yaw backup system’s technology is based on an electrical storage system which is capable of reacting immediately in the hardest conditions of voltage drops, as well as adapting its operation to demanded energy. The system comprises a power conversion system (PCS) and a unique battery energy storage system (BESS).

This innovative technology provides the power required to control the yaw systems, protecting the structural integrity of the wind turbine during a power failure. This helps the wind sector overcome challenges in terms of security, sustainability, and efficiency.

Benefits at a glance

• Improves wind turbine performance in hostile conditions.

• Ensures a safe and reliable operation.

• Reduces maintenance costs and longer plant life, resulting in productivity growth.

• Enables early profits through the high Return on Investment.

• Prevents great damages on wind turbines and other assets resulting in serious consequences for the energy sector and financial losses.

• Avoids the use of diesel generators, except as a last resort in emergency situations.

• Contributes to the massive penetration of wind energy into the grid to enable the clean energy transition.

• Offers real-time operation monitoring and control, including alarm event captures.

System overview

Battery-based yaw backup system products are designed to ensure power supply in case of grid losses. The system is a key element for safeguarding the reliability and availability

A

of wind turbine farms, specifically the yaw system and other single-phase critical loads that constitute each wind turbine. These products are adapted to the standards of each country or the application requirements.

Battery-based yaw backup system products are characterized by their great capability to be customizable, allowing configuration according to the desired power converter topology and load type.

The power converter systems are configured using a unique conversion line that works as both a rectifier and an inverter. Alternatively, they can include a back-to-back converter to connect the DC bus at any voltage and frequency input.

On the other hand, they can also incorporate a DC/DC converter to

improve the battery operating voltage, and thus overcome battery voltage limitations.

Regarding the output configuration, they are capable of supplying three-phase loads (3p and 3p+N). Additionally, they can incorporate single-phase loads (1p+N).

The systems use advanced modulation techniques to synthesize any type of voltage or current waveform to the output, leveraging the fastswitching speed of the IGBTs controlled by the converter control unit.

Power conversion system

The main objective of the power conversion system (PCS) is to transform the continuous energy of the batteries into alternating current to supply the system loads. It is materialized as a cabinet which is composed of a Power Stack in charge of adapting the energy, a harmonic filter to improve the signal quality, protections against shortcircuits and over-voltages, and a general control device (CCU). Furthermore, it is configured to respect demanded grid codes and keep the batteries healthy in a good term.

Energy storage system (ESS)

The energy storage system (ESS) is in charge of basic tasks of battery control and maintainability to guarantee the health and efficiency of the storage system. The battery cells are assembled with LFP technology (lithium iron phosphate), which is characterized for its high energy density. This type of cell provides great durability in the long term. Besides, the device has a compact design for easy future upgrades thanks to its form factor and cell dimensions.

The architecture of the ESS control is divided into three levels. The most basic module in the structure is the BMS, which is connected to each battery — there will be as many BMS units as the number of batteries. Subsequently, all BMS units are governed by a power distribution unit (PDU) which

is responsible for obtaining voltage and temperature measurements, among other tasks. At the highest level of the hierarchy is the battery administration unit (BAU), which acts as a gateway between PCS and ESS. In this connection, the BAU manages the sending and receiving of data with the PDU, as well as being responsible for the main connection between the CCU and the BAU.

Securing a Workforce for Americaʼs Offshore Wind Future

by Ross Gould

America’s seas are changing. Our first commercial-scale projects now stand with turbines towering over the water, providing electricity to communities and tens of thousands of homes across the East Coast. This burgeoning industry promises a cleaner future, reduced reliance on fossil fuels, and a surge in domestic energy production. However, unlocking its potential hinges on developing a skilled workforce ready to design, build, and maintain these massive wind farms.

Federal researchers estimate that anywhere from 15,000 to 58,000 full time workers would be required each year to ramp up worker supply. Many of these jobs are highly skilled or require specialized training, creating uncertainty regarding whether we will hit the target. Our ability to address these challenges and build a workforce for the offshore wind industry will determine not only our ability to meet our goals, but also how much benefit our local communities see from the proliferation of renewable energy.

The good news is the U.S. already has a thriving existing workforce quickly gaining experience as the first projects move through construction into operation and maintenance. There are marshalling ports with electrical workers and fabricators completing components, dockworkers and harbor personnel moving components, production workers manufacturing, assembling, and welding critical components for towers and transition pieces, and vessel operators moving components and people offshore to installation sites. Already, with just two projects under construction, thousands of workers are building offshore wind farms or actively participating in the supporting supply chain. And the federal government has approved five more projects, with dozens more in the queue.

Just a glance tells a story. At the Port of Providence, 160 people assembled advanced foundation components for South Fork Wind and the soon to begin Revolution Wind Project. In Western New York, a manufacturing facility added 100 workers to manufacture and assemble components for anode cages and other secondary structural steel components. And over 100 onshore workers performed the onshore electrical work to connect South Fork Wind to the electrical grid.

Workers with experience in the U.S. are even being tapped to meet global workforce demand. In fact, two-dozen U.S. pile drivers spent the winter working on a project in Europe. With the industry anticipated to need tens of thousands of workers in the next decade in the U.S. alone, global demand is rising simultaneously. This gives workers just getting started a big advantage, because they have the added potential to find work both domestically and abroad.

Despite these gains, however, there are still significant gaps to address, including a lack of understanding that the opportunity exists. Many potential workers remain

unaware of the breadth and variety of well-paying careers available in offshore wind. This lack of education about the industry, along with the substantial training needed, translates into a shortage of skilled labor, which threatens to halt wind’s momentum.

The seeds of a future workforce must be sown early. Introducing offshore wind into curriculums, particularly in coastal communities, can spark interest in young students. Interactive programs and field trips to operational wind farms can cement the industry in the minds of our youth, fostering a generation excited about clean energy careers. In a bid to meet this need, Rhode Island recently established the Nation’s first Offshore Wind Energy High School Certification program in 2018.

However, the challenges we face extend beyond mere awareness — we need to scale to meet demand in an efficient and predictable manner. Existing workforce education and training programs should be adapted to incorporate offshore-specific knowledge. Courses in wind turbine technology, marine operations, and specialized safety protocols can equip prospective workers with the foundational knowledge necessary to enter the industry. Government funding can also play a critical role in supporting the development of a skilled and diverse offshore wind workforce. Grants can be allocated to create specialized training programs, expand apprenticeship opportunities, and promote diversity and inclusion initiatives within the industry.

Promoting diversity, equity, inclusion, and accessibility (DEIA) within the offshore wind workforce is essential for long-term success. Companies and workforce development organizations should connect with communities that have been left out of past energy projects, and work with them to develop inclusive training programs. Funding can support programs that encourage women, minorities, veterans, and individuals with disabilities to pursue careers in offshore wind. A diverse workforce brings a wider range of perspectives and experiences to the table, helping to foster innovation and problem-solving.

For experienced workers in related fields, transitioning to the offshore wind industry can offer a new and exciting career path. Developing specialized transition programs can bridge the skill gap, allowing experienced workers from sectors like oil and gas, or even traditional wind energy, to smoothly transition into offshore wind careers.

As is the case in the broader offshore wind industry, collaboration across organizations will be critical to building a strong offshore wind workforce, particularly between industry leaders and educational institutions. By fostering ongoing dialogue, training programs can be tailored to meet the specific needs of the industry, and ensure graduates possess the necessary skills to hit the ground running upon entering the workforce.

Addressing the current knowledge gap and fostering a diverse and skilled workforce can unlock the true potential of offshore wind energy, and propel the nation towards a cleaner, more secure energy future powered by Americans working quality jobs.

Harnessing the Power of Floating Offshore Wind

by Sigurd Solheim Pettersen, Bente Pretlove, and Kristin Nergaard Berg

The US offshore wind sector has entered 2024 with cautious optimism as the industry shakes off negativity from last year, ready to apply learnings from a challenging 2023 to the year ahead. There are already key projects in the pipeline, including the Revolution wind project expected to start construction in the spring, and the commercial CVOW project expected to start construction in May.

Joining the United States, Canada has recently announced their plans to develop wind off the coasts of Newfoundland and Labrador. With several offshore wind areas in waters too deep for fixed-bottom technology, floating wind has emerged as the technology developers are evaluating for their projects. Floating wind allows access to the US West Coast for offshore wind development and greater wind resources farther off the East Coast.

A recent report forecasts that, by 2050, 17 percent of all accumulated offshore wind installed capacity globally will be floating offshore wind. This means that approximately 270 GW of floating offshore wind will be installed in the next 30 years. This will require around 18,000 turbines, each mounted on top of floating units weighing more than 5,000 tons, and secured with so many mooring lines that if they were tied end-to-end, they would more than wrap around the world.

While the sector presents significant opportunities, it also comes with a range of new challenges as developers consider projects further offshore in deeper waters. This growing market is still in its relative infancy; for floating offshore wind to achieve its full potential, it must overcome a number of challenges, including technical, commercial, and societal.

Driving standardization to support reduced LCOE

As a relatively new technology with few operational turbines, the levelized cost of energy (LCOE) for floating offshore wind remains very high. For this technology to scale faster, it is paramount that the LCOE be reduced as much and as quickly as possible. The global average LCOE for floating offshore wind is predicted to fall 75 percent by 2050. This drop will depend on factors like cumulative installed capacity, economies of scale, and serial manufacturing, with reductions in the cost of floating structures and turbines being the main contributors. LCOE will vary significantly between global regions. Wind farm size increase will be a key driver of LCOE reduction, as moving from pilot to commercial sized wind farms allows for scaling effects and standardization, which again will become a key enabler for industrialization, further driving cost reduction post 2030.

More than 50 floating wind concepts are currently under development. While innovation is required to push performance, reduce weight, withstand harsh environmental conditions, and allow efficient operations, the wide range of concepts can also represent a barrier for the cost reduction needed in the industry to eventually attract subsidy-free investment. The number of different fabrication approaches can make it difficult for the supply chain to provide efficient fabrication facilities and standardize their logistics and processes.

One way the industry can tackle the challenges of expanding application, scale, and reducing costs without compromising safety, is through Joint Industry Projects (JIP’s) that aim to bring standardization across the floating offshore wind industry.

Floating wind farms, further from shore in deeper waters, will require floating substations with development of dynamic cables with higher voltage and power levels than currently available, as well as electrical equipment such as transformers and switchgear. One JIP is aimed at aligning best practice and closing the gaps in available substation standards to enable the scaling of floating offshore wind. Phase 1 has just been completed and confirmed the feasibility of floating offshore substations and export cables, identifying technology gaps and highlighting the maturity of AC solutions compared to DC. For Phase 2, new participants are called in to join the project, which will contribute to the 2024 update of industry standards for offshore substations and dynamic high-voltage export cables.

Another JIP focuses on mooring and cables. The growing floating offshore wind industry will require innovative solutions for floating structures, mooring arrangements, cable solutions, and materials. Mooring and cable equipment is a key cost driver within floating wind. A key task of the JIP is to provide new and valuable insights on load and capacity of these critical components; the recommendations will form the basis for tomorrow’s design requirements.

Finally, a recently launched JIP aims to optimize requirements for concrete floaters specifically tailored for floating offshore wind farms. Concrete floaters are a cost-effective and environmentally friendly alternative to steel floaters, particularly for larger turbine sizes. An alternative to steel, concrete engages a larger part of the supply chain in floating wind.

Ocean stakeholder collaboration

As offshore wind picks up pace, the demand for ocean space will also increase. It is essential that this expansion takes place in a safe, equitable, and sustainable manner. Therefore, it is critical that ocean stakeholders build strong working foundations. One way this is being facilitated is with a three-year scenario building project that

The project will focus on establishing a common knowledge base among ocean stakeholders, enabling them to identify synergies, resolve conflicts, and negotiate winwin solutions while safeguarding ocean health. The Utsira Nord floating offshore wind licensing area in Norway will act as one of the case studies in the development of the toolbox. The toolbox will be developed in a way that allows for scaling and adaptation to different regions and international settings, including the North American market.

Future marine spatial planning processes will increasingly need to emphasize coexistence with nature and other human activities. A toolbox will help offshore field developers and operators gain a competitive advantage by more quickly understanding how future competition for space will influence their overall risks and opportunities in relation to other ocean users, as well as the marine ecosystem. It will support strategic planning and stakeholder dialogues in connection with offshore field developments, marine spatial planning, and ecosystem management.

As part of the project, partners will seek to capture the impact ocean industries have on each other and the environment, as well as the cumulative effects from all industries combined. The goal is to contribute to trust and transparency in stakeholder dialogues in the early stages of project planning. Offshore wind developers can take advantage of new methods to plan for coexistence by taking a collaborative approach to accounting for the impact of future uncertainty on nature

not conflicting with fishing banks.

Supporting a clean energy future

To reach ambitious floating offshore wind targets, the industry must accelerate commercialization while managing risks related to cost, technical novelty, acceptance by other ocean stakeholders, and environmental impacts.

In the next five years, we expect continued technology development in floating wind to reduce cost, scale production, and broaden applicability.

As an increasing number of floating wind turbines come into operation, the industry will learn more about day-to-day operations, wind turbine performance, and events such as major component replacement. Those learnings will undoubtedly spur new developments, and play an important role in the transition to a cleaner energy supply.

On-site Generation of Wind Energy is Key to Recovery After Extreme Weather Events

by Claus Lønborg

When thinking of renewable energy sources, you most likely picture solar panels or massive wind turbines, churning out energy to reduce the strain on electric grids and helping towns and businesses meet lofty sustainability goals. However, when an extreme weather event occurs, these solutions alone are often not able to support recovery or restoration of power due to cloud cover, rain, flooding, excessive heat, heavy snow, or damage by debris.

Snowstorms, hurricanes, and heatwaves wreak havoc on the grid, creating nightmares for essential facilities like large warehouses, distribution and data centers, factories, and airports, all of which rely on heavy and uninterrupted power loads to sustain operations. The repercussions of power outages, brownouts, or loss of climate

Solutions

Extreme weather significantly impacts the power generation infrastructure, causing disruptions in electricity supply, rate escalations, limitations on and soaring costs of insurance coverage, damage to the infrastructure, and physical hazards. Considering the aging nature of our existing transmission systems, the need to diversify on-site back-up power alternatives has become more

The risk of outages not only affects other sources of remote or back-up power like diesel, propane, and coal, but these sources are not clean and sustainable solutions. In rethinking their approach to clean energy resilience, experts are prioritizing diversification of energy sources, infrastructure, and distribution, focusing more on maximizing on-site generation.

fall and winter, offering a perfect complement to solar energy. One way to lessen the stress on national grids is to produce what you consume to keep your properties active in rain, snow and other adverse weather. Along with solar, wind energy helps site owners have a balanced load and be more independent of the grid. Innovation in the renewable energy sector has led us to harness the power of wind for scalable, on-site generation by individual users. These units are growing in popularity and efficiency, especially in remote locations and areas where the increasing intensity of storms has escalated power outages on aging grids (and solar alone is not a viable, year-round option).

This clean energy distributed power alternative is being adopted by a growing number of companies with large manufacturing facilities and warehouses such as ecommerce, logistics, automakers, and airport terminals that require a heavy power supply — in place of traditional carbon-based fuels typically used for back-up power generation.

There have been numerous attempts to integrate wind harvesting technology into the built environment, but none without its challenges. Traditional wind turbines have been limited by environmental and visual impact constraints in the built environment. Even a smaller scale traditional wind turbine doesn’t sufficiently mitigate these legacy challenges.

As companies seek to mitigate climate change and control the input and output of energy at their facilities, experts explored ways that wind harvesting units can be deployed on buildings for individual use with the development of quieter, motionless, and more efficient wind harvesting units suitable for single buildings.

On-site solar is limited by available solar resources, and subject to seasonal and daily variations (bright summers, cloudy days, dark winters). Solar energy is typically produced mid-day and not at night or during inclement weather. Innovation in wind generation technology is creating a large opportunity to maximize on-site power as either an integrated system with solar and battery storage, or a stand-alone system where solar is not suitable. Wind harvesting units generally produce more electricity in the late afternoon and nighttime, and during the

On-site power supply will become more critical to counter the more frequent, extreme weather conditions we expect to see in the future. A disruption to a single power plant during an extreme weather event would have dire consequences for a large area. However, buildings operating with their own supply of power via a wind harvesting unit coupled with solar, would be able to enhance operations by both saving on the power they consume during normal conditions, and protecting them from grid outages caused by these growing numbers of intense weather events.

In 2021 and 2022, we watched as Europe worked its way through a challenging energy crisis, where oil, coal, and power prices surged, stretching resources. Further, Europe depended on deliveries of coal and oil from Russia, which was disrupted by the country’s ongoing tensions with Ukraine. In coal-reliant South Africa, residents experience brownouts for hours each day as aging coal plants are prone to breakdowns, and new energy generation facilities are yet to be built. Companies in the Netherlands have gone back to utilizing diesel generators as backups because the national grid cannot supply the needed power any longer.

As a society, how do we solve the challenge of our reliance on electricity and carbon-based fuels? Building centralized power plants requires major and costly investments in the global grid. The world is seeing the electrification of everything – from handheld devices, cars, trucks, and even whole buildings, which means our demand for electricity will continue to increase, putting more strain on the grid. Extreme weather conditions coupled with the uptick in demand for electricity is pushing the limit of what grids can supply. Given the escalating frequency of extreme weather events around the globe, it’s more important than ever to seek alternative methods of energy production.

Development of new on-site power generation systems are highly necessary to adopt and strategically implement. Distributed resources are the new frontier. New innovations are required to drive the scalability of the energy transition and establish the level of resilience necessary based on the dramatic impacts of extreme weather.

38kV vacuum circuit breaker OEM

EMA Electromechanics has designed and manufactured the high-speed Grounding Breaker, a technology created to mitigate islanding over voltage in solar or storage energy MV circuits. In solar/BESS applications, during a line-to-ground fault or a load rejection, the MV circuit might be islanded with the inverters connected for some cycle of wave in order to commit to the voltage ride-through (NERC PRC-024). Inverter’s islanding detection method (IDM) might mis-operate and remain generating for some cycles. At risk are cable insulation and surge-arresters. The high-speed grounding breaker is a fast and clear signal to all inverters shut down at the same time (avoids unnecessary ride-through) and is a reliable TOV protection. EMA offers 38kV vacuum grounding breakers and conventional circuit breakers for outdoor applications.

PV in the Age of Climate Readiness

by Ameer Abuhamdeh

The new frontier of solar adaptability requires the right groundmount systems for today’s extreme weather and terrain.

Climate readiness is the new normal in utility-scale PV. EPCs, developers, and asset owners facing complex projects must assess ground-mount solutions designed specifically for the harshest weather. More than performance in heavy snow, deep freeze, and high winds, climate readiness requires intelligent systems to keep solar assets safe during weather events while generating peak production all year.

But it's not just weather challenges. Today’s PV systems must go on less-than-ideal sites, with steep or uneven terrain and unforgiving soils. Many may ask how to guarantee foundation reliability on such sites, and ensure seamless connections with racking and tracking systems. Also, how do EPCs and developers contain installation risks while optimizing long-term O&M? Overcoming these challenges shapes the future of climate readiness for utility-scale PV.

Whether it's a system on a Caribbean reef, a hilly and rocky site in the Northeast, or a single-axis tracker (SAT) system in high winds, racking solutions that push innovation’s boundaries offer unique advantages.

Making solar possible in paradise

The 4-MW solar and 10-MWH storage microgrid on the idyllic Bahamian island of Chub Cay required strategic planning and creative solutions. Caribbean businesses struggle with exorbitant electricity prices, poor reliability, and polluting diesel-powered generators. Because solar costs less than half of conventional power, a private resort on Chub Cay chose to install a self-sustaining solar microgrid with battery storage.

Above ground, the corrosive marine environment and expected hurricane wind speeds required specialized foundation and racking systems capable of withstanding extreme conditions. The situation was equally unfriendly underground, where coral and solid limestone soils made traditional pile foundations impossible. Ground-mount foundations required 5,700 pounds of tension capacity, which meant that ground screws were the only viable option to penetrate the island’s solid oolite limestone. A screw with a custom spiral thread allowed a lower embedment depth for a faster and more costeffective installation. The alternative (driven piles in costly concrete foundations) simply wouldn’t work, either structurally or financially.

Managing risk also was a key consideration. Ground screw foundations eliminate refusal risk. Using a fixed racking system that could integrate seamlessly with the ground screw foundations was an important requirement. The high-strength steel, low-tilt racks offered a customized system able to tolerate hurricane-force winds up to 185 mph and gusts up to 210 mph, with a specialized module frame mounting for extra durability.

Despite being the largest solar plant in The Bahamas and one of the largest grid-forming systems, the microgrid was built and commissioned without delays in eight months.

Contouring the steepest slopes

When a community solar project needed a tracking system for a 6.5-MW project on a mountainous site in Maine, it involved considering varying elements of risk. With a state average snowfall of 50 to 80 inches, weather was a key influencer in selecting and designing a solar tracking system.

Rocky and frost-susceptible soil made ground screws the only viable foundation option, eliminating refusal risks and ensuring against frost heave despite the 50-inch frost depths.

Precipitous slopes throughout the rocky landscape presented another challenge altogether. A highly flexible SAT conformed to the undulating terrain with a leading 20 percent grade tolerance. Using project feasibility software helped optimize the SAT to generate 4.3 percent more energy than an alternative tracker with a 15 percent slope tolerance, and 4.7 percent more than a 10 percent slope-tolerant system. Because of this field adjustability, site grading costs were substantially reduced while maximizing the land’s higher yield potential. The result was a 7.1MW capacity potential without grading; the other options offered 5.9 MWs (15 percent SAT) and 4.6 MWs (10 percent SAT) without grading.

There are a few ground-screw-adapted SATs on the market. When assessing options, developers should consider the interface between the tracker and the foundation. An adaptable A-frame structure and telescoping screw extensions deliver bestin-class vertical adjustability of up to 36 inches to overcome undulating topography, significantly reducing grading requirements.

Weathering extreme wind with a 1P SAT

A 3-MW community solar project in Illinois chose a new 1P tracker for its value-engineered, windresilient design and ease of installation. Proprietary engineering tools were used to determine site-specific wind and snow loads, ensuring an optimized system. Through its resilient design, the 1P was deployed to withstand the 105-mph wind load in Illinois. Over 10,000 wind coefficient values were processed alongside an average of 63 different load combinations. This allowed engineers to accurately calculate the peak load combinations across the site based on terrain, topography, and location. With real-time feedback, this automated process helped

To achieve aerodynamic stability, the engineering team spent more than 700 hours conducting wind tunnel testing with a leading third-party testing laboratory, optimizing the balance of wing length, stiffness, and damping. This analysis determined the best stow strategy for the 1P system: a zerodegree angle to reduce static and dynamic wind forces, with dampers to ensure aeroelastic stability.

Ensuring tracker performance with advanced real-time software

For asset owners requiring the highest level of performance from their tracker systems, intelligent software can increase energy yield, protect assets in inclement weather, and minimize downtime.

Look for systems that maneuver each tracker row to limit shading, maintaining optimum exposure and production to maximize project efficiency and value. Systems that include a weather station, network controller, and one row box per tracker row work together to provide real-time performance data.

Bringing it all together with one integrated partner

When dealing with tough weather during construction, or simply integrating fixed-tilt or SAT systems with different foundations, it’s best for the manufacturer to also lead the mechanical installation.

A 61-MW data center campus project in the Nevada desert near Reno illustrates this point. After previous efforts failed to drive a pile system into the site’s rocky terrain, it took employing and integrated a survey, design and engineering, manufacturing, and complete mechanical installation offering to finally expedite the project’s construction schedule. In the end, three rock-drill machines secured ground screws, assembled and positioned the legs, and installed the fixed-tilt racking system quickly and efficiently.

After the Storm

A plan to minimize damage and speed solar restoration

by Ananda Hartzell

2023 set a new record for the number of weather disasters surpassing $1 Billion in damage. Utility-scale solar will face increasing vulnerabilities as the industry grows amid continued catastrophic events. Owners and asset managers can minimize risks from two directions: a strategic plan to prevent losses, and an effective approach to speeding recovery.

• Evaluate Alternatives

Owners and investors are often shocked at the cost of restoring damaged solar plants, including the capital cost of restoration and lost revenue from downtime. Outdated and hard-to-find replacement equipment, racking redesign, and reconfiguration due to evolving changes in form factor and electrical characteristics of PV panels, the degree of experience and/or availability in the workforce, and long lead times — all of these contribute to protracted and costly restoration timelines. Planning ahead becomes even more critical as insurance companies assess their own exposure in light of weather disasters that lead to skyrocketing premiums and reduced coverage. The result? A greater burden of risk is falling on asset owners.

Proactive planning – an underutilized tool

Globally, for every $100 spent on weather disaster recovery aid in 2010-2018, as little as $0.47 was allocated to mitigating disaster risk . Switching the focus from after-the-fact rebuilding to proactive prevention can protect against unnecessary lost

Key to any recovery plan is a threshold for determining when a PV module is broken and should be replaced. While it seems like a simple evaluation, there are complexities involved; modules may not indicate obvious or damage visible to the naked eye. A preventative framework should include tests to determine and measure module efficacy. Recovery planning must also factor in the availability of replacement panels. Older plants may have obsolete modules that are no longer available in the market, with limited options to match the form factor of the current products. This impacts the design of the tracker system used, along with other potential issues that cause a wide range of challenges and delays during the recovery process.

Weathering the Terrible Twos

How wind combined with hail or overcast gang up on solar trackers

by Matt Kesler

If someone someday writes a history of the solar tracker industry, the author will surely tell of creativity and hard work by thousands of engineers and scientists, over many years, to make trackers more impervious to extreme weather, while also pushing cost down and energy production up.

It’s fun and gratifying to be part of that team – an international collective who have mostly never met each other.

(And I’ve always taken pride when telling my kids about my work!)

The weather aspect of this story is complicated – developing hardware and software to enable trackers to withstand extreme conditions including wind, overcast, cold, snow, and hail. But what’s really complicated is two or more weather events happening at the same time.

And when you put large numbers of trackers – up to 10,000 or more at a single site – into operation for 30 or 40 years or longer, it’s inevitable that whatever can happen, will happen. This complicates both the structural design and the functionality requirements (the software) immensely.

The objective is to protect both the trackers, and whichever modules are chosen by the system designers, 24/7/365, under any combination of weather conditions reasonably likely for the 30 to 40-year life of the solar power plant.

For example, you may reasonably expect wind and hail. Wind alone is a complex matter. Steady wind poses one kind of risk, wind gusts another, and changes in wind direction require more intelligence from the tracker control system. Some trackers are prone to “galloping” – periodic twisting of the tracker in response to gusts – and require solutions to minimize that risk. Most tracker control systems deal with wind by going to a wind stow position when the steady wind exceeds a given speed, or if three-second gusts exceed a higher threshold. The best wind stow position may change depending on conditions such as the direction of the wind. It is also common for a tracker’s range of motion – such as 120 degrees, from 60 degrees east of horizontal to 60 degrees west of horizontal – to be reduced gradually as the wind rises toward that steady wind threshold. The challenge is even more complicated when wind is combined with another weather event, such as snow or hail.

Hail in particular poses a challenge, since minimizing wind risk generally means facing the modules into the wind, while hail risk is minimized by facing the modules away from the wind. Tracker angles chosen to minimize risk of damage in high winds vary from 0 degrees – that is, horizontal – to 30 degrees. Both modules and trackers are strongest when the front of each module is facing into the wind, so ultrasonic anemometers have a big advantage as they report not only wind speed but also wind direction.

In the event of large hailstones in low wind, the hail stones tend to fall nearly vertical. Small hailstones in high wind will fall up to 30 degrees from vertical. In other words, tracker angles which minimize wind risk put the modules nearly perpendicular to the trajectory of the hailstones, and more-or-less maximize hail risk. Similarly, the angle which minimizes hail risk – modules at high tilt and facing away from the wind – maximizes wind risk.

When both hail and high winds occur at the same time – which is common in much of the continental US – sophisticated methods are needed to minimize the total risk.

Short-term wind and hail forecasts, along with local real-time wind speed and direction data, can enable effective risk mitigation strategies. If a tracker control system gets the data it needs from those wind and hail forecasts, and gets that information at the right time (typically 15 to 30 minutes in advance of the hail), and if the control system has software which takes into account weather data and the capabilities of the tracker (including range of motion and motor speed), then both wind risk and hail risk can be minimized — generally without additional hardware cost.

Some market reports indicate that Texas was the biggest solar state in 2023, and likely to be the biggest again this year. Texas gets more hail than almost any other state. So, a focus on wind and hail is timely and will help owner/operators to get insurance at lower cost.

Figure 1: Wind risk is lower on the left tracker, but hail risk is lower on the right tracker.

This wind/hail risk mitigation strategy is an emerging and value-adding feature of advanced tracker control systems.

Another odd couple is wind and overcast.

In overcast conditions (not passing clouds) energy production can be improved by not tracking the sun. Irradiance in these circumstances comes not from a single part of the sky (the sun) but from a diffuse cloud layer.

Tracking the sun does not increase production. In fact, it can even reduce production, because at angles far from horizontal, the modules are not exposed to the whole sky. Highest energy production in overcast conditions comes from exposing each module to the whole sky, even as gray as it is. In this case, production can be increased by putting the modules at an angle nearly horizontal.

But some trackers – and some modules – can be at risk at tilts near to horizontal; some trackers experience “flutter” at such low tilt angles, even at low wind speeds. The need to avoid very low angles for an extended period of time may require software to maximize production while keeping the modules at a slightly higher angle (but still close to horizontal) and then return to tracking as soon as there is visible sun.

Someday, somebody ought to write another chapter in the solar tracker history. (But no matter how good it is, I probably won’t be able to get my kids to read it.)

Simple. Solid. Sustainable.

• Specified for use with leading pipe and pile-based racking and tracker systems

The design of the tracker structure can make these challenges easier by reducing or eliminating some of the problem modes. For example, a tracker structure may not be vulnerable to flutter or galloping due to correct balancing of factors such as friction and torsional strength.

power distribution centers, and data center interconnection.

Prefabricated buildings are typically engineered based on customer specifications, state regulatory codes, and requirements, and are engineered to mitigate risk from environmental factors and extreme weather conditions. Here are 10 factors companies must consider when designing a prefabricated substation control building.

1. Location: Control buildings should be situated close to the substation equipment, and in an area that is safe and accessible for all personnel. The location should also consider any zoning or land-use regulations that may apply, as well as the location’s geography. If the final site location is a coastal or dusty environment, building manufacturers can apply a special protection package to the exterior wall and roof sheeting to mitigate the effects of harsh climate conditions while protecting the building and extending its use.

2. Environmental considerations: The control building should be designed to withstand local weather conditions, including wind, snow, rain, seismic, and temperature extremes. Manufacturers utilize high-grade steel in the construction of prefabricated buildings to

Designing Substation Control Buildings for Rough Conditions

enhance structural integrity. Steel is durable, long-lasting, entirely recyclable, and makes for a costeffective solution. It can also be modified easily, paving the way for even greener infrastructure. Control buildings contain sensitive equipment and data, so security considerations must remain a priority when designing a control building. This may include access control systems, surveillance systems, and other security measures to prevent unauthorized access. Some building manufacturers offer additional security shielding for ballistics, electromagnetic pulse (EMP), and fire resistance.

4. Size: The size of the control building should reflect the size of the substation and the amount of control and electrical equipment that needs to be protected. It should be large enough to accommodate all necessary equipment and provide adequate space for personnel to comfortably move around and complete tasks. The size of the building should also comply with the National Electrical Code requirements for clearance and egress. Consult your local jurisdiction for more information.

5. Electrical and mechanical requirements: The control building should be designed to provide adequate electrical and mechanical systems to support the substation equipment. This may include power and lighting systems, HVAC systems, fire suppression systems, and customer provided equipment such as relay racks, control and monitoring equipment, or switchgear. HVAC systems are sized to the interior and exterior environment of each building — calculations are completed based on the building dimensions, interior equipment installed, and the final geographic location.

6. Proper insulation and sealing: Ensure buildings are well-insulated and sealed to prevent water infiltration, air leakage, and heat loss during extreme weather events. This helps maintain comfortable interior conditions and prevents damage to the building envelope. A standard 2:12 roof pitch, for example, allows for adequate water run-off and snow shedding when compared to flat or minimally sloped roof designs.

7. Maintenance: Prefabricated buildings can be designed with an exterior or interior steel sheeting that includes a maintenance-free Polyvinylidene Fluoride (PVDF) resin coating. Spraying or dip coating this thin layer of PVDF material to the sheeting’s surface provides protection against environmental factors such as UV radiation, moisture, and corrosive chemicals. PVDF coating enhances the durability of the metal sheeting contributing to the overall structural integrity of the building.

8. Future expansion: The control building should be designed to allow for future expansion as the substation grows and new equipment is added. This is especially important as new solar fields come online and connect to the grid.

9. Regulatory requirements: Before design can begin, make sure to research all regulatory requirements that apply to the design and construction of the control building. Requirements include compliance with local building codes, national safety standards, and environmental regulations. Upon completion, all control buildings should receive professionally engineered and stamped structural drawings and calculations.

10. Adopt green building practices: Incorporate sustainable design principles into building projects, where applicable, to mitigate the long-term impacts of climate change and extreme weather events. This includes utilizing energy-efficient materials, renewable energy sources, and green infrastructure solutions.

The design of a prefabricated substation control building involves careful consideration of factors such as location, environmental conditions, security, size, and regulatory requirements. Manufacturers that utilize high-grade steel and advanced engineering techniques can ensure structural integrity and resilience to extreme weather events. Implementing proper insulation, maintenance practices, and green building principles can further enhance the durability and sustainability of these essential infrastructure components.

Water Scarcity May Hinder Global Solar

by Prakash Govindan

With the energy transition now officially in the fast lane, solar energy will soon represent the backbone of the global energy system. Already, solar is on track to make up more than half of global electricity generation by 2050, with more than 510 GW added in 2023 alone. This surging demand is rapidly transforming economies, underpinned by the growing need for robust manufacturing capacity.

manufacturers to massively cut down on uptake and treatment waste while reducing climate liability.

As the race to build domestic supply chains heats up, manufacturers everywhere are facing a new challenge: the need to efficiently manage and conserve water to protect local communities and the environment. It’s an issue that hasn’t attracted significant mainstream concern — yet — but as water-intensive photovoltaic (PV) manufacturing continues ramping up and countries become increasingly prone to climate-fueled droughts, water scarcity could pose a real threat to production.

The good news is that manufacturers have the chance to proactively mitigate concerns by implementing up- and downstream water management processes and technologies, which are now broadly available and highly cost-effective, providing a means of reaching sustainability targets.

Manufacturing fever goes global

Few industries can claim a success story like solar PV, with annual manufacturing capacity expected to hit more than 1,000 GW in 2024 — an unprecedented boom in just a few years. For now, the overwhelming majority of solar manufacturing occurs in China, including over 80 percent of all polysilicon, wafer, cell, and module development. Other countries, however, are quickly ramping up their own industries, eager to ensure economic competitiveness and shore up their domestic supply chains

Regions all across the world, including Europe, North America, South Asia, Africa, and the Middle East, have begun prioritizing PV supply chain diversification, with many passing legislation to stimulate domestic growth. One report even found that a few countries have reached cost parity with Chinese solar manufacturers, showcasing how quickly the global market is diversifying. At the same time, 2023 was just named the hottest year on record, putting growing pressure on the world’s freshwater supply at a time when manufacturers are looking to accelerate their operations and increase their water uptake.

While some countries will face more severe droughts and water shortages due to climatic differences, all will face a level of disruption. Rising temperatures, paired with increased manufacturing activity and growing populations, is a recipe for water scarcity. And since industrial use is deprioritized when freshwater is hard to come by, this will inevitably lead to expensive shutdowns for solar manufacturers bound by inefficient water uptake and treatment processes.

Ultrapure water, for instance, is essential for cleaning and etching PV systems (which enhances solar cell efficiency), but this generates substantial wastewater volumes in the form of reverse-osmosis reject and ion exchange regeneration brines. Simultaneously, the manufacturing process of solar PV electrical contacts and wiring requires the use of metals, with aluminum, copper, and silver being particularly important. To eliminate impurities during processing, cleaning solvents like nitric or hydrochloric acid are employed. The resulting wastewaters are highly acidic and contain residues that demand treatment. Having the right equipment and systems in place to do so effectively can make a world of difference in manufacturers’ ability to navigate water restrictions.

Impetus for water conservation

Manufacturing commercially available solar PV, regardless of brand or panel efficiency, requires significant water volumes; it’s used for etching, cleaning, and cooling, among other purposes. Solar manufacturers also have wastewater discharges that need to be carefully managed and reduced (another waterintensive process) to comply with stringent regulatory requirements and prevent environmental contamination. Water recovery for secondary and tertiary usage is, therefore, critical to enable

Fighting climate change is at the heart of what the solar sector does, but it’s critical that manufacturers and other stakeholders not lose sight of other challenges. As one of the basic necessities for life on Earth, freshwater demands careful management, especially by heavy industrial users. Maximizing water conservation and reducing necessary discharges will ultimately benefit solar manufacturers, allowing them to get ahead of impending regulations, and ensure reliable production that can meet the demands of today’s ambitious developers. The time is now for the solar sector to embrace water conservation.

Navigating Sensitive Environments for Solar Construction

by Mike Choi

he global shift towards clean energy — exemplified by the widespread adoption of solar power — is not only a beacon of hope for a sustainable future, but also comes with heightened expectations for responsible project execution. From the initial planning stages to the completion of every solar construction site, a commitment to environmental stewardship is essential. This commitment becomes even more crucial when dealing with particularly sensitive environments which require special measures to minimize ecological impact. Understanding these environments and proactively addressing the potential challenges they pose are critical components of successful solar construction planning and execution.

Sensitive environments impacting solar construction

Solar construction companies find themselves at the forefront of environmental responsibility, especially in areas with heightened ecological sensitivity. Several environmental challenges may arise when

In the pursuit of solar energy, companies may encounter the need to protect endangered species or delicate ecosystems. Mitigation measures could include refraining from using certain herbicides, relocating plants or animals, avoiding specific areas, suspending operations during critical seasons, and implementing various protective measures. This stresses the delicate balance required to harmonize solar development with existing ecosystems.

National and regional regulations impose minimum requirements for environmental protection, with a special emphasis on sensitive areas like wetlands. Additional regulations may vary based on the type of land and ownership status. Solar installations on public lands come with their own set of guidelines and restrictions, adding an extra layer of complexity to

Altering the ecosystem

Large-scale solar installations bring about both visual changes and significant environmental transformations. The introduction of shade, redirection of water flow, and other alterations can impact local growing conditions. If the construction access route involves traversing wetlands, pastures, or farmland, the responsibility for full restoration post-project completion may fall on the solar construction company. However, with foresight and careful planning, the impact can be mitigated.

Solar installations have the potential to disrupt both habitats and migration corridors through the installation of fencing or other structures. Such disruptions can have longlasting effects on plant and animal populations by interfering with mating processes or the transportation of seeds. Balancing the needs of solar construction with the preservation of these critical corridors is a delicate task that requires strategic planning.

Effective strategies for navigating sensitive environments

Fortunately, there are practical and effective strategies to mitigate the challenges associated with solar construction in particularly sensitive environments. These strategies go beyond mere compliance with regulations, and embody a proactive commitment to environmental preservation.

Preserve biodiversity

Local ecosystems, often unnoticed by the naked eye, play a crucial role in supporting countless native species. Understanding and protecting these ecosystems are essential for a thriving environment. Measures such as preventing the transfer of invasive species and planting pollinator-friendly native species can help mitigate disruption and contribute to a healthier ecosystem.

Maintain wildlife habitats

Implementing wildlife-friendly fencing, thoughtfully positioning solar panels, and considering migration corridors during installation are key tactics to minimize disruption. Preserving as much existing vegetation as possible and restoring any

disrupted areas with native species not only safeguards wildlife habitats, but also fosters long-term sustainability.

Protect water quality

The implementation of a Stormwater Pollution Prevention Plan (SWPPP) is crucial to defining and implementing measures for reducing erosion and runoff. Strategies such as fencing, drainage systems, bales, and other tactics help keep waterways clean. Recognizing that the SWPPP is a living document that must be regularly updated ensures ongoing protection of water quality.

Collaborate with experienced site access providers

Engaging companies with extensive experience in managing clearing requirements and executing largescale civil construction is necessary for successful utility-scale solar projects. While many providers may claim that they are able to handle a project due to their possession of construction equipment, the unique challenges of solar sites require specialized knowledge. A qualified site access partner with experience in navigating solar construction in sensitive environments can bring a strategy that minimizes impact and complies with regulatory requirements.

Collaborating with experienced site access providers not only ensures the work is done right the first time, but also reduces the likelihood of incurring penalties or fines. Such a partner will bring extensive experience from various large-scale utility projects, having encountered and effectively addressed a diverse range of challenges. With a trustworthy site access partner, navigating regulatory requirements becomes seamless, assuring collaboration with qualified crews that can handle common scenarios. The production of clean energy through solar power is not just about harnessing the sun's rays, it’s also about treading lightly on the Earth.

Sustainable solar construction demands a comprehensive understanding of the environments in which projects exist, as well as providing a commitment to proactive measures that go beyond

regulatory compliance. By implementing effective strategies to preserve biodiversity, maintain wildlife habitats, and protect water quality, and collaborating with experienced site access providers, the solar industry can contribute significantly to a greener and cleaner future. Each solar construction project becomes an opportunity to demonstrate that responsible environmental stewardship can coexist with the quest for clean energy, ensuring a harmonious balance between human progress and ecological preservation.

Shining a Spotlight on Solar Panel Manufacturing

by Ricardo Jimenez

Since the passage of the Inflation Reduction Act nearly two years ago, U.S. solar panel makers navigate a promising market amid production, legal, and investment considerations

Nearly two years after U.S. President Joe Biden signed the Inflation Reduction Act into law, it is time to take stock of the scope of the major climate and energy initiative and its provisions for solar panel manufacturers in the United States.

The White House is being bullish on the new law, saying “Outside groups estimate the Inflation Reduction Act’s clean energy and climate provisions have created more than 170,000 clean energy jobs already, companies have announced over $110 billion in clean energy manufacturing investments in the last year alone.”

But it is also important to dig deeper and address some of the questions and issues surrounding solar panel production.

the IRA — such as tax credits — are benefiting U.S solar panel manufacturers, and offer a glimpse into the next phase of solar panel production in the U.S.

Overseas production

At this moment, anyone producing panels outside of China faces an uphill battle. The U.S. has a moratorium in place until June with Chinese-made modules circumventing U.S. import duties. By contrast, European producers of solar modules are doomed to disappear due to the overwhelming stocking of low-priced Chinese modules without restrictions.

U.S. solar companies face other hurdles. Solar panel makers in Asia planning to export panels or even some raw materials to the States must provide a full traceability report showing their sources of polysilicon are not from the Xinjiang region in China, where the U.S. government says there are forced labor camps. That puts an added layer of pressure on U.S. companies to perform due diligence.

At the same time, there are some common misconceptions about solar panel production in China. The thinking is that, because they are cheap, the panels must be of poor quality. The truth is that the most advanced solar modules do, indeed, come from China, which has an indisputably long lead in the industry.

Additionally, virtually no solar manufacturing machinery is produced in the United States, as most of it comes from China, and a few companies in Germany and Italy.

While these factors may seem to be stacked against U.S. solar makers, there is actually good news on the horizon. Chinese products will face higher taxes when their

moratorium is reversed in June. That means that any Chinese modules that are made overseas and brought to the U.S. will cost much more than those made in the States. That will help to boost the local industry for solar panel manufacturers.

Benefits of the IRA provisions

Just as the White House has signaled, the main benefit of the IRA is that a new solar industry has spawned across the United States. New job opportunities exist for thousands of Americans in new, clean technologies that will continue to evolve — due largely to the provisions afforded to U.S. solar panel makers under the new law.

For instance, the IRA has a provision known as “Section 45X,” which is a tax credit for businesses that manufacture and sell energy components. To qualify for the 45X production tax credit (PTC), U.S. makers need to sell their production to non-related clients based in the U.S.

Solar makers can either cash or trade their tax credits set at 7 cents on the watt. Thus, a 1-gigawatt factory can theoretically generate a non-taxable $70 million per year on the tax credits alone. These tax credits will impact the production of solar panels in the U.S. We are seeing a huge flow of investment in the industry, which will increase competition and help to pull the prices down, thereby leveling the field. To wit, the past year has seen an uptick in announcements of new factories across the nation.

Developers can also integrate upstream as they seek to secure the supply of their needed modules, and finance these acquisitions with the tax credits themselves.

What’s next?

The remainder of 2024 and beyond looks promising for U.S.-based solar panel manufacturers from a production and investment perspective. In terms of solar panel production, solar panel makers will likely increase the sourcing of raw materials from local suppliers. In fact, most new entrants into solar panel manufacturing foresee this; they’re already investing heavily in integrated operations to secure the sourcing of solar cells instead of importing them (and facing possible confiscations at customs checkpoints).

As these new integrated solar panel manufacturers begin to operate and expand, the cost of producing modules in the U.S. will inevitably begin to decline.

Also watch for local manufacturers to begin shifting to the more efficient N-Type solar cell, referring to the “negative” carriers of the electric charge in the materials. Why? Most cell manufacturers — including the cell machinery manufacturers in China — have aggressively begun the transition to N-Type cells. With this, some processes within the manufacturing will also begin to change.

Finally, investors will continue to aim to understand the dynamics of the PTC, which is a key to boosting investments into the solar panel manufacturing sector. The IRS rules with respect to the cash treatment are not completely clear, leading to an increase in the trading of these tax credits. The tax credits can provide healthy, shortterm returns to investors helping to motivate larger funds to back these investors, thus increasing the number and amount of financing opportunities for the industry at large.

Ultimately, the solar panel manufacturing market in the United States is growing and has great promise. But it will also be critical for manufacturers to effectively navigate the maze of production, legal, and investment issues as the industry evolves in the coming months.

Identifying owners of mineral rights beneath your solar project

by Jillian Ballard

What’s underneath the surface of the land that you plan to develop and who owns it? Identifying owners of mineral rights is critical for utility-scale solar energy projects, especially in regions where these rights are legally separable from surface rights. This refers to the severance of underground mineral rights from the surface rights of the property. Mineral rights can include natural gas, oil, coal, or any other types of minerals found beneath the surface of the land. Owners of these rights have the legal authority to mine, exploit, or produce the minerals beneath the surface. Importantly, these rights can be sold or leased separately from the land itself, leading to situations where surface rights and mineral rights have different owners.

In a “worst case” scenario, a recent ruling by a federal judge ordered the removal of an 84-turbine, 150-megawatt wind farm for encroaching on the Osage Nation’s tribal mineral rights. The court ruling came after the Interior Department sued the company for failing to get a mining approval for the project, which may cost the company more than half a billion dollars.

Preliminary research

It’s always a good idea to develop a cordial relationship with landowners. They are likely to have the best knowledge of the ground and what is under it. While their understanding of the legal history may not be perfect, they generally have valuable background information.

Land and mineral rights transactions are recorded at the county assessor and clerk’s offices. Many counties now offer online databases, but in-person visits may be necessary. State geological surveys and the U.S. Geological Survey (USGS) can also help identify regions with potential mineral deposits and areas where mineral rights might be actively leased or sold.

Due diligence and title search

Mineral coverage is an ALTA endorsement offered by the title insurance company. It is typically required by lenders or investors as an addition to their policy, so it’s critical to get the title insurance company involved as early as possible to strategize what they may need to issue this endorsement. Typical considerations may include whether there are any active wells or mines in the area, whether there are any active leases given by the mineral owners, and whether the developer intends to leave part of the project area open to protect the mineral owner’s right to exploration. It is important to note that, in many states, mineral owners are the dominant estate holder and have the right to enter the surface of the land and use it to access the minerals.

Trace the history of mineral rights ownership, looking for deeds, leases, wills, and court records that mention mineral rights, noting any divisions or retainments. When faced with complex mineral rights ownership issues, it may be beneficial to hire a professional landman or a title attorney. They possess the skills and knowledge to navigate the intricate landscape of ownership records, interpret legal documents, and identify

the rightful owners. The goal is to establish a chain of title — a sequence of historical documents reflecting the transfer of mineral rights through time. Laws governing mineral rights can vary significantly by state, with some states granting more privileges to mineral rights owners than others. Familiarize yourself with pertinent federal and state legislation that may influence your project.

Negotiating with mineral rights owners

Many landowners have a clear understanding of the mineral rights associated with their property. By engaging in a dialogue with the landowners, you can gain insights into the ownership structure and their expectations. It is important to develop trust so that you can explore lease agreements that align with their interests as well as the goals of the project.

Compensation for mineral rights owners can come in many forms, including upfront payments, royalties, or a combination thereof. Be prepared to discuss how your renewable energy project aligns with environmental sustainability goals, potentially mitigating concerns from mineral rights owners about the impact of development on the land. Legal counsel specializing in mineral rights can help craft agreements that protect the interests of all involved.

Recording as protection

To eliminate as many title issues as possible, the developer should record memoranda of site control as early as possible. In most states, the person with the most superior rights is the person who has recorded first. The act of recording a document

protects the rights of everyone who is a party to that agreement. Recording a document puts the world on notice, in the public record, of the rights contained therein. Signing a contract with a landowner protects the developers interests with that landowner. Most importantly, recording a contract or a memorandum protects the developer’s, interests against any other developer or landowner who may come along and want to purchase or lease the property. The person who records their interest first is described as having priority over people who record later in time.

coverage for the usual transactions encountered by title insurance carriers. There are several ALTA endorsements which specifically pertain to renewable energy projects and closings.

Final thoughts

Identifying and negotiating with owners of mineral rights is a complex process that requires due diligence, legal knowledge, and strategic negotiation skills. When armed with a willingness to find mutually beneficial solutions, project developers can build cooperative relationships with mineral rights owners, paving the way for successful utility-scale project development.

Supercharging Battery Energy Storage Infrastructure

by Anthony LaMantia

The global power industry is changing rapidly. First and foremost, utilities are seeing increased public pressure from consumers to source their energy via more renewable methods. Yet business and industry are also exerting more pressure for change as they manage their scope 2 and 3 emissions to meet increasingly ambitious net zero goals.

The rise in variable generation, such as solar and wind, has heightened the need for utility-scale battery energy storage to help mitigate the effects of intermittent power production and maintain grid stability. Battery storage facilities can act as a load by absorbing excess generation. They can also smooth out system operation by supplying power boosts to support voltage, frequency, and peak demand needs.

Owners and operators of these assets are often perfectly positioned to take advantage of fluctuating energy markets, but only when their operations empower them to be nimble. Such operations require the comprehensive visibility and easy control provided by fit-for-purpose green energy management solutions, with integrated asset management and supervisory control and data acquisition (SCADA) software.

Increased complexity of managing I/O

One of the primary factors that gives utility operators pause as they pursue battery storage projects is the perceived complexity of the shift from a very operational technology (OT)-centered infrastructure, to a more information technology (IT)-focused one. While a traditional power generation automation project had dozens of cabinets where engineers wired in transmitters and other field devices, renewable automation projects are more IT-based, with many datalink connections via Ethernet or fiber optics. I/O are often addressed as IP devices, and gather data using industry-standard protocols.

This shift from hard I/O to soft I/O typically results in a less tangible I/O base, resulting in hundreds or thousands of I/O points across the system. While more power capacity means more capability, it also means far more communication points.

The I/O generated by individual battery cells or modules is managed by an OEM battery management system (BMS), and DC to AC voltage conversion is handled by the power conversion system (PCS or inverter), typically provided by a different OEM. Depending on site configuration — a single unit representing a collection of similar battery modules, a plant consisting

of multiple units, or units or plants connected to renewable generation like solar — the breadth of equipmentgenerated I/O that needs to be managed by operations could be overwhelming, which could result in inefficient support of daily energy storage site operations.

Moreover, with the intricacies of the modern supply chain, there is no guarantee that every piece of equipment will be sourced from the same manufacturer. Ultimately, a site could very easily end up with numerous BMS and PCS installations from a variety of OEMs — which escalates when more storage is added to a fleet — increasing operational complexity.

As operators try to manage their daily tasks (how many batteries are at full capacity, how many have faults or alarms, how many are in automatic versus manual control), they will need to be trained to operate and support multiple systems. This will require extra time and cost to navigate different interfaces for the same issues, while introducing delays to what are often time-critical tasks.

A single solution for unified control

The organizations having the most success establishing, maintaining, and optimizing battery storage operations are bringing all their systems together into an integrated solution, with a single dashboard for a clear and comprehensive view of operations. These implementations rely on field-proven and fit-for-purpose green energy management solutions based on SCADA software created by automation suppliers with decades of experience in both the automation and energy industries (Figure 1).

The best energy management systems aggregate all the battery storage I/O into a central point, and they use one intuitive dashboard to provide clear operational visibility and control of hundreds or thousands of devices and I/O. Plant staff have continuous access to aggregated data for efficient operation and troubleshooting of their battery systems from the same location, without jumping between operating environments.

Using built-for-purpose battery energy management solutions with SCADA software not only saves time by eliminating the need for operators to travel to one or multiple battery energy

sites, it also helps enforce consistency and repeatability of operations. Operations and maintenance staff can be trained on one system and know that their skills will apply to every piece of equipment, regardless of OEM. They also gain access to broad, reliable, comprehensive customer support to help them navigate the complexities of aggregating a wide array of disparate systems. When organizations select proven, experience-backed energy and asset management software, they are also more likely to be able to control additional assets (wind, solar, hydro, and even fossil-fuel sites) alongside their battery energy storage. This increased flexibility makes it easier to bring multiple critical systems together into a remote operations center, where the organization’s best and most experienced personnel can more efficiently manage a wider array of fleet-wide assets (Figure 2).

A foundation for a greener future

Battery storage is a new frontier for many utilities venturing into the renewables sector; there are often many unknowns. While a wide variety of energy management and SCADA solutions for battery storage exist, the most effective solutions across the lifecycle of a company’s equipment will be those built from the ground up by an automation solutions provider with deep expertise in energy generation.

Not only will such solutions be easier to install, configure, manage, and maintain, they will also be designed with the capability for expanded operations, making it easier to use to efficiently monitor all the energy storage and generation assets the organization owns or may acquire. The full access to data, clear operational visibility, and intuitive control provided by an integrated green energy and asset management solution can be the foundation for decades of safe, efficient, and profitable operation.

ESS offers a solution to increasing extreme weather

by Jim Brown

The summer of 2023 was the hottest in recorded history, hitting the United States with disproportionate force. A climatology report by PBS explained that the terrain in and surrounding the U.S. contributes to powerful competing air masses that result in extreme weather, inflamed by the fact that many of the major population centers in the country have been built near climate propellants like the ocean.

Though extreme climate events have increased, municipal infrastructures have not been updated to address the effects of worsening weather, which leaves U.S. homes and their owners vulnerable to the ravages of the elements. Nearly 70 percent of homeowners experienced a power outage during 2023, interrupting access to home appliances, lighting, charge for cellphones and other communication devices, and internet use. Grid-dependent homeowners faced with an outage had no choice but to wait for the utility company to resolve the issue in order to restore power.

Freedom from weather-related outages

As extreme weather increases, the option to relinquish grid-dependency and enjoy uninterrupted power grows more alluring. Energy storage systems (ESS) provide a way to store power for the home. Like a battery, residential ESS gather energy that can be used in an outage or during peak consumption times when energy prices spike. ESS can be installed on a floor or mounted to a wall, and are often kept out of sight in a basement or garage. Homeowners can choose the number of units in their ESS to tailor its performance to the size and desired energy needs of their home.

A shared and often weather-strained power grid means rising blackouts, brownouts, and outages that take away access to essential appliances people rely on for health, comfort, and safety. Homeowners with ESS, however, have an additional resource available to them during an outage; they can simply pull stored energy from their ESS to power certain home appliances.

In the case of an extended outage, the power stored in an ESS can be used for longer periods of time by only powering essential appliances like refrigerators or medical devices. ESS that are connected to rooftop solar panels can be recharged on sunny days to extend their power capacity during long outages. Energy independence mitigates the hazards and fears associated with losing power by giving homeowners more control over the power in their homes.

Solar panel or grid coupling options

Many homeowners have already invested in rooftop solar panels to minimize their reliance on the grid. While solar panels can help homeowners reduce and control their electric bills; instead of shoveling hundreds of dollars to the utility every month, adding an ESS increases their energy reliability. By storing energy from PV panels, the ESS ensures an additional source of power for the home so appliances can effectively operate day and night.

Yet for homeowners who do not have rooftop solar panels, ESS remains an equally viable option: ESS can connect to the grid and store grid-generated power, so when the entire neighborhood or town is experiencing a blackout, homes with ESS can stay powered on. During dangerous weather events, many ESS can be controlled from a mobile app to enable homeowners with ESS installed outdoors to operate the device from the safety of their homes.

Incentives

Like solar panels, residential ESS require an upfront investment, which may be eligible for an offset by state-specific incentive programs or The Inflation Reduction Act (IRA) credits, or, in some states, both. Homeowners may qualify for up to a 30 percent investment tax credit for home energy storage installation — which covers both the cost of the storage

system and installation fees — until 2033. Previously, only homeowners with both an ESS and rooftop solar panels could qualify for this tax credit, but newer regulations allow those with and without rooftop solar panels to apply for the tax credit, making home ESS more widely accessible and affordable under the IRA. Several states offer their own additional ESS incentives, including California, New York, Florida, Ohio, Texas, Colorado, and several more. These state-specific incentives range from property tax exemptions, to sales tax exemptions, to rebate programs that earn homeowners credits (which can be cashed) based on the amount of energy their ESS produces. Many resources are available to homeowners to assist them in determining which incentives may apply to them, including their ESS installer. Another way to offset costs is to use ESS to power homes during peak consumption times. After charging during lower usage periods when power prices are more stable, many ESS can utilize a self-consumption mode during peak usage periods, saving homeowners money by using their own stored power instead of paying the higher costs associated with high usage times.

Extreme weather events are intensifying, as is the climate’s impact on the grid. A residential energy storage system provides a dependable solution for homeowners looking for energy independence. Energy storage empowers all types of homeowners to take control of their energy costs and reliability, so when the grid goes down they’ve got power, even when their neighbors don’t.

Embracing New Fire Safety Standards for BESS

by Doug Fisher

On April 19, 2019, a thermal runaway event took place in a battery energy storage unit (ESS) located within a building in Surprise, Arizona. The ESS was provided with fire detection and fire suppression, which both activated. Approximately five hours after arriving on the scene, the responding fire department opened a door on the ESS, and a deflagration event occurred, severely injuring four firefighters. The event was a catalyst for the need for updated fire safety standards, including increasing fire department awareness of the hazards of an ESS, as the ESS was reportedly installed in compliance with applicable codes and standards at the time of its commissioning.

Just four months after this incident, the National Fire Protection Association (NFPA) debuted the first edition of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems. The release of NFPA 855 was a three-year effort to address fire safety concerns related to ESS installation and operation. Since the release of NFPA 855, the model building and fire codes in the United States have also been updated to address these same concerns.

Whenever new regulations are issued, there is always a concern that these standards could be detrimental to business operations. The current edition of NFPA 855 applies to the “design, construction, installation, commissioning, operation, maintenance, and decommissioning of stationary energy storage systems (ESS), including mobile and portable ESS installed in a stationary situation” to provide “the minimum requirements for mitigating the hazards associated with ESS” . While NFPA 855 is a fire safety standard to protect people, property, and the environment from a thermal event, compliance with NFPA 855 can also have a positive effect on operational mission continuity. The key to NFPA 855 is to engage qualified professionals and the fire department early in the site development process.

Typically, there is a three year or more lag between the development of codes and standards like the International Fire Code and NFPA 855; many jurisdictions in the U.S. have not yet adopted the most current editions of these fire safety standards. Developers may be aware of these codes and standards or, more importantly, that the current editions provide more guidance on proper site location and interface with the responding fire department. Not understanding that these standards exist (or their requirements) can not only delay commissioning and start-up, but also require modifications of the installed ESS.

A key focus of the fire safety standards has to do with preventing “thermal runaway.” This is when the temperature of a battery cell increases uncontrollably which can result in a fire, explosion, or flammable and toxic gas evolution if not properly mitigated. Numerous media stories have shown the effects of thermal runaway in batteries for e-mobility devices (e-bikes, e-scooters, and similar). Thermal events in e-mobility devices, particularly when occurring inside a building, have resulted in significant fires, injuries, and deaths.

NFPA 855 includes the development and review of items such as:

• Emergency planning and training

• Hazard mitigation analysis (HMA)

• Combustible storage

• Equipment

• Installation

• Smoke and fire detection

• Explosion Control

• Fire control and suppression

Successful implementation of NFPA 855 begins with the selection of the battery ESS. As technology continues to change and improve, battery ESS are constantly evolving with battery chemistry, energy storage capacity, energy storage management systems, and safety features. Some battery ESS have internal fire safety features such as hazardous gas venting, smoke detection, fire suppression, or specialized engineered solutions, while others may need these systems provided independently from the battery ESS.

Fires in battery ESS units, however, are very rare. According to the BESS Failure Event Database maintained by the Electric Power Research Institute (EPRI), there have only been 16 documented battery ESS failure events in the U.S. in the five years since the Surprise, Arizona event. While this number is higher than fire safety professionals would prefer, proper planning can limit the effect of a thermal event on the public and responding fire department.

Planning at procurement

Early in the project planning process, developers and integrators work together to determine the overall

Determining the need for these fire safety features starts with fire testing of the battery ESS. Most battery ESS units are now required by NFPA 855 and model fire codes to be listed to UL 9540, Energy Storage Systems and Equipment . While there is an allowance in NFPA 855 for a field evaluation to be performed for nonlisted ESS, UL 9540 requirements provide valuable information related to how the battery ESS reacts in a thermal event. As part of the site development process, a hazard mitigation analysis (HMA) should be performed that reviews the results of the UL 9540A testing and applies that information to the individual battery ESS, adjacent units, and the overall site. The HMA is an analysis that looks at the consequences of a variety of failure modes, including thermal runaway. The HMA will assist in siting of the battery ESS to protect exposures on the site by determining the minimum distance from items such as public walkways, lot lines, important structures,

Rugged battery connectors

Battery connectors from Weidmuller USA for BESS applications are engineered to handle high currents, allowing for efficient energy transfer and reduced power losses; designed to withstand harsh environmental conditions; are user-friendly with mechanisms that prevent accidental disconnections; contact made of copper alloy finished with silver and approved according to UL 4128 to warrant the best electrical contact with more than 100 operations of mechanical connection and disconnection (without load); on the wiring side, options for conductor crosssections from 10mm² to 95mm²; on the mating part, a busbar where the conductor can be easily connected on the device by means of a cable lug; color coded connectors (orange = positive; black = negative) on both the connector and the mated busbar connection; connectors are key coded on both sides to alleviate the possibility of user error; and a locking mechanism to fasten the plug and the socket.

and/or mitigating factors, and adjusting for them early in the site development process, is key to a successful permit issuance and timely commissioning and approval by the local fire department. Developing the HMA late in the construction process can result in the installation/provision of significant mitigating factors (installation of fire-resistive walls, field evaluation of the battery ESS, addition of fire detection/fire suppression systems) after the battery ESS is installed on-site. This can easily delay project commissioning and start-up.

Final thoughts

While NFPA 855 and associated fire codes and standards can appear to cause additional headaches and costs for energy storage site developers and integrators, it saves you later. Early understanding and implementation of these regulations increase interaction and understanding with the responding fire department, which can result in successful project commissioning and startup. If a thermal event were to occur, implementation of the HMA can result in limited downtime and any effect on adjacent equipment at the project site, as the event may be contained to a single energy storage unit.

Fire Risk May Threaten Energy Storage Boom

by Brian Cashion

As the world accelerates its transition to renewable energy sources, the deployment of energy storage solutions has surged to meet the demands of this ongoing transformation. Battery Energy Storage System (BESS) capacity is likely to quintuple between 2023 and 2030, reaching a cumulative 411GW, as battery technology becomes indispensable for grid stability and reliability.

With this surge, however, comes a pressing need to mitigate the fire risks associated with BESS. Effectively managing the fluctuations in renewable electricity generation on the power grid is vital as fossil fuels are phased out; the scale of growth needed to meet net-zero targets underscore the critical importance of ensuring the safety and reliability of BESS infrastructure.

As the industry grows, so does the fire risk

Lithium-ion batteries are the most common and preferred choice for grid-scale storage systems, based on cost and energy density considerations. This market dominance, however, comes at a price – these batteries post a significant fire risk. With demand growing 30 percent annually up until 2030, the number of BESS fires is set to go up exponentially. To make matters worse, a recent survey found that 26 percent of battery storage systems have fire detection and suppression issues, while 18 percent also had issues with the thermal management system.

The fire risk is not simply a question of mitigating damage to the BESS asset. Smoke from thermal runaway in lithium-ion batteries is not just flammable, but toxic. With the expansion of energy storage in the next decade, this poses a serious danger if the system is installed near a dense or heavily populated area. Central to mitigating this threat is ensuring not only that the batteries themselves cause a fire, but also that fires starting around other components in the BESS asset do not spread to the battery rack.

Current fire

suppression solutions don’t go far enough

Currently, industry recommendations prioritize the implementation of water deluge protection systems in all BESS projects. While these systems play a crucial role in providing cooling and fire suppression, they fall short of preventing catastrophic events such as thermal runaway. They also fail to adequately protect all components within a battery asset. To address these shortcomings, the industry must pivot towards prioritizing comprehensive protection for the entire BESS asset.

Safeguarding all components of a BESS asset is paramount, as this significantly reduces the risk of fire propagation from electrical cabinets to batteries a problem that has occurred on other renewable energy assets with the same equipment (such as wind turbines). These components also represent 40 percent of the total asset cost, amounting to up to $500,000. By implementing protection measures for electrical cabinets and incorporating total flood protection for battery racks, the industry can not only reduce the risk of fires spreading between components, but also minimize reliance on "last resort" deluge systems, which are often activated after a fire has already escalated.

Financial impact of fires necessitates upgrading fire suppression solutions

The financial implications of fire incidents on BESS assets are substantial, with developers, owners, or operators facing potential costs of up to $2 million. These costs include the catastrophic loss of assets and revenue depletion resulting from up to 1.5 years' worth of downtime. Further costs can continue to stack up following a BESS fire, including increased insurance premiums, environmental damage, and reputational harm to businesses and industries. In contrast, the cost of fitting or retrofitting comprehensive fire suppression solutions represents only a fraction of these potential losses.

The industry must also address the growing issue of false activations in fire suppression systems, which carry a substantial financial cost. False activations can reach costs of up to $900,000, posing significant challenges in terms of clean-up efforts and downtime when utilizing aerosol or water deluge solutions. Mitigating the risk of false activations is essential not only to minimize financial losses, but also to maintain operational efficiency, grid stability, and reliability.

Further responsibilities for developers

The potential for increased fire incidents poses broader implications for the BESS industry. Public opposition to BESS projects could intensify, further complicating industry growth and hindering progress towards renewable energy goals. To mitigate these risks, developers must actively engage with local authorities, fire, and rescue services, establishing communication channels and fostering collaborative partnerships to enhance fire safety protocols and emergency response capabilities.

The increasing recognition of the importance of energy storage is attracting a diverse range of participants. Concurrently, the projects themselves are evolving and installations are becoming larger and more complex. In this dynamic landscape, clear and transparent communication is essential for effective risk management. As projects expand and become more intricate, the dissemination of relevant information and best practices to mitigate potential risks effectively must be prioritized. Collaboration and knowledgesharing among industry participants, regulatory bodies, and research institutions are crucial to foster a culture of safety and resilience in the evolving energy storage sector. In conclusion, as the global energy transition gains momentum, addressing the fire risks associated with Battery Energy Storage Systems is paramount. By prioritizing comprehensive fire suppression solutions, engaging with all relevant participants, and

Securing Our Energy Infrastructure with Microgrids

by Dane LaBonte, Mike Voll, and Tony Zavanelli

The impacts of climate change are becoming increasingly more apparent as communities around the world experience extreme weather events. From hurricanes and floods to droughts and wildfires, these types of events can have profound negatives effects on our energy infrastructure. This is a major challenge that will only continue to grow as the frequency — and severity — of these extreme weather events increases.

So, how can we protect our grid systems and promote energy security for those who need it? One good answer is implementing microgrids.

What are microgrids?

Microgrids are what they sound like: A small, selfsustaining local energy grid that exists within the

larger grid system. A grid consists of power sources, users, wire connections, and a system to control everything. Microgrids consist of all that, they are just a smaller version of it. However, a defining element of a microgrid is its ability to connect and disconnect from the larger grid. This proves helpful during outages related to extreme weather events or system failures that can cause blackouts or brownouts.

Microgrids are becoming increasingly popular in achieving energy security because they provide power to customers during grid outages. They are also a growing segment of the energy transition, and represent the shift from centralized power towards more localized and distributed generation solutions. The aim? To protect communities, provide resiliency, and, in some cases, enable the transition to cleaner forms of energy.

Another great thing about microgrids is how they can pull power from distributed energy resources (a combination of different power sources). For example, a microgrid can have a baseload generation of electricity from traditional fossil-fuel sources. It can also include solar panels, wind turbines, and hydroelectric facilities. Furthermore, it can have battery energy storage systems to gather renewable energy when it’s generated, and discharge the energy when it’s needed. As we look to the future, microgrids may be able to utilize alternative energy solutions like hydrogen and small modular reactors. This makes them an attractive option for communities looking for energy security and making efforts to decarbonize.

grid at all. Off-grid communities must generate power themselves. Traditionally, this has only been possible with fossil fuel resources. But microgrid solutions are increasingly enabling these communities to integrate renewables, which reduce their dependence on fossil fuels.

The second key benefit concerns essential services. Microgrids can provide resiliency for essential electrical systems such as those used by hospitals, data centers, and more. These institutions need to have power to operate 24/7, which is especially true during extreme weather events. There is a high-value proposition for these types of facilities to implement their own microgrids. If people are hurt or injured during a hurricane, for example, we need our hospitals to function in order to treat people in need. Furthermore, we need to make sure our communications systems are up and running during these events so emergency response teams can coordinate with each other — and the community — to achieve the best and safest outcomes.

It's clear that microgrids can benefit communities in need of solutions for energy security. To get a better perspective, let’s look at an example of what can happen when they don’t have one.

Who can benefit from microgrids?

Everyone can benefit from microgrids, but they are especially useful in a couple of key settings. The first is rural and remote communities, which are generally serviced by long power lines that are vulnerable to disruption, if they are connected to the larger

A case study in Texas

In February 2021, Winter Storm Uri swept through the southern United States. It had a profound impact on the state of Texas, causing record snowfall and low temperatures in the state that wasn’t necessarily prepared for the severity. This is because the grid there was not designed for these types of conditions. The result? A crisis of energy supply and demand. During the winter storm, Texans were forced to turn up their thermostats to keep from freezing. Unfortunately, while the demand for electricity to heat homes was increasing, the ability to produce

that electricity was waning; oil and gas pipelines froze, wind farms were iced over, and even nuclear power plants were taken offline due to the frigid conditions. This resulted in several challenges for communities in Texas. More than 3.5 million Texans experienced power outages, leaving people without electricity to keep the lights on, heat their homes, or charge devices to keep in touch with loved ones and the local authorities. These power outages had knock-on impacts. Freezing temperatures and power disruptions affected water treatment facilities, which led to boil water notifications warning local residents to boil their water before drinking it to make sure it wasn’t contaminated. Power outages also strained fuel supplies as people collected fuel to run generators or were forced to stay warm in their cars. There were also food challenges as people were unable to cook their food or keep it fresh in the refrigerator.

Strategically deployed microgrids could have increased the resiliency for these communities. Not only could have safeguarded the water systems, but they could have ensured emergency facilities remained online, minimizing the impact to public transportation and safety.

Driving energy security with microgrids

As extreme weather events continue to grow in both quantity and severity, we need to prepare for the new normal. One of the best ways to do that is by protecting our power infrastructure. Microgrids can help us do that in a more resilient and sustainable way. Plus, they can help communities to diversify their energy sources and integrate renewables like wind, solar, hydropower, and more.

Microgrids should be increasingly more common as we drive the energy transition forward. Achievable for users big and small, microgrids are particularly effective in rural and remote communities. By adopting this sustainable energy solution, we can help to keep the lights (and heat!) on during extreme weather events.

Running Hot and Cold

Hydrogen fuel cells pass the test

by Carly Demanett

As industrial operations look for opportunities to decrease their carbon emissions, hydrogen fuel cell vehicles and batteryelectric vehicles have emerged as potential solutions. These power options generate zero carbon emissions at the tailpipe, and are available for a growing range of vehicle types. They also meet new emissions requirements for industrial vehicles. However, for fleet managers, there are other key factors to consider when determining which solution is the right fit to power their operations. Industrial equipment often has to operate in extreme temperature conditions, either due to climate or the operating environment. Fleet managers need to know whether vehicles will perform under conditions with extreme heat or cold.

Recent studies show that hydrogen fuel cells outperform battery-electric vehicles (BEVs) under severe temperature conditions. For operations in locations that regularly see subzero temperatures or temperatures over 100°F, this can have a significant impact on productivity and efficiency. Certain industries such as mining, shipping and ports, and material handling, can also offer unique operating environments with excessive heat or extreme cold. Underground mining can generate heat at the job site, which leads to high-temperature environments. Materials handling in cold storage facilities can require forklifts and other vehicles to operate in below-freezing temperatures. Shipping and port operations are located across the globe, from the Equator to the Arctic, and require vehicles that can maintain a high workload across a range of climates and temperatures. For both high-heat and sub-freezing environments, hydrogen fuel cells have demonstrated superior performance compared to battery-electric vehicles.

One study by hydrogen researchers in Bangladesh found that Proton-Exchange Membrane Fuel Cells (PEMFC) performed with greater efficiency in high-heat situations. The study not only concluded that optimum operating temperature results in the highest performance, high-temperature conditions, it will also “increase the performance and efficiency, power production, voltage, leakage current, but decreases mass crossover and durability” of hydrogen fuel cells. This demonstrates that hydrogen fuel cells are a viable option for equipment that needs to operate in extreme heat due to location or job site environment, as they maintain or increase efficiency as temperatures increase. The performance of hydrogen fuel cells far outweighs any slight decrease in durability, providing overall reliable power in high-heat operations.

Additional research and development of polymer fuel cells has expanded the capabilities of these vehicles to operate in higher temperatures. While previous iterations of these fuel cells required large radiators and other cooling systems to maintain optimal operating temperature, new developments by researchers at Los Alamos National Laboratory allow polymer fuel cells to operate at 80-100°C, reducing the overall power system size and weight. This is especially important for transportation and trucking vehicles where vehicle weight has a large impact on efficiency and profitability. The lower-weight fuel cells allow long-haul trucks to gain the range and performance benefits of hydrogen fuel without adding significant weight.

Many work sites operate under extremely cold temperatures. To determine which power system performed best in these conditions, Cleveland State University conducted a study in partnership with eight transit agencies. The study tracked the performance of battery-electric and hydrogen fuel cell buses in sub-freezing temperatures, measuring their performance when shifting from ambient temperatures of 50-60°F to 22-32°F. While both power systems saw a decrease in overall performance, the battery-electric buses had a significantly greater drop. Buses with electric batteries suffered a 32.1 percent drop in efficiency and a 37.8 percent drop in range. Hydrogen fuel cell buses performed better, with only a 28.6 percent drop of efficiency and range decrease of 23.1 percent.

Perhaps the most extreme temperature scenarios for hydrogen fuel cells can be observed in NASA’s current and future fuel cell applications. Hydrogen fuel cells have been in use on NASA missions since the 1960s. From the icy planet of Neptune to

locations as it provides operations with greater flexibility in their vehicle capabilities. Fleet managers do not need to worry about their operations pausing if optimal temperature ranges are not met. Vehicles can continue powering work no matter the climate or job site temperature conditions.

For operations and fleet managers looking for effective ways to transition their fleets to zero-emission vehicles, hydrogen is a viable option that provides peace of mind. Hydrogen fuel cells’ ability to support productivity and uptime goals, in addition to sustainability goals, makes them a logical selection across industries, locations, and operating conditions. To support the broader adoption of hydrogen fuel cells and other hydrogen fuel technology, hydrogen fuel generation and its distribution infrastructure will need to expand to ensure broad access to this lower-emission energy solution.
