Then:

“2020 is going to be a super year for nature and people.”

Now:

“If 2020 was a haircut, it would be a mullet.”

The past year has given us many things to think about and take action on. It’s refocussed our priorities in ways we never dreamed necessary. It’s made us appreciate the little things in life and earnestly consider the big picture. It’s made things we thought were inconsequential into game changers. Some really big, serious things happened this past year that made us all a little more serious about everything. But, as my colleague, Meg’s father said, “From the day you’re born ’til you ride in a hearse, things are never so bad that they couldn’t get worse.” So now, for just a moment, let’s take a breath of clean, fresh air, and relax a little. Let’s be thankful for all the things that were good last year and trust 2021 will make up for all the things that weren’t. The team at North American Clean Energy is thankful for all of our readers, contributors, and advertisers. We wouldn’t have made it through without you. This one’s for you...

Biodegradable face mask

Since the onset of COVID, the demand for single-use plastics has spiked worldwide. The BioProducts Institute at the University of British Columbia, develops ways to use renewable resources existing in nature as alternative solutions to fossil fuel derived materials. One major development has been the Can Mask, a biodegradable face mask created with natural cellulosic fibres and nano-materials made from wood-based products that match the performance of disposable polypropylene masks. Along with tackling COVID’s plastic problem, the BioProducts Institute is actively developing other solutions for wearable textile materials used for Personal Protective Equipment (PPE) and structural materials like thermal insulation, something integral for cold winter months, as people spend more time at home than ever.

Sustainably built coffee store

Canadian green construction technology company, Nexii Building Solutions Inc. (Nexii), has constructed a first-of-its-kind sustainably built Starbucks drive thru store in Abbotsford, BC, Canada. The sustainably constructed Starbucks café has been built using Nexii’s green construction technology, which is designed to reduce the store's carbon emissions by approximately 30%. Nexii’s proprietary material, Nexiite, which is used within its building panels, is more thermally efficient and less carbon-intensive than concrete. In addition, when assembled the Nexii panels create an airtight building envelope. Together, this markedly improves a building’s energy efficiency and, in turn, significantly lowers the greenhouse gas emissions for ongoing building operation. The Starbucks café’s wall and roof building panels were precision manufactured in a Nexii production facility and the onsite assembly of the airtight building envelope was completed in just six days. Nexii also aims to tackle the construction industry’s waste problem head-on and its building solution reduces onsite waste to near-zero. Nexii is continuing to invest in research and development to eliminate waste from its processes entirely.

Energy harvester device to replace batteries

OnePieceADay (OPAD) /// www.onepieceaday.ca

Rensselaer Polytechnic Institute /// www.rpi.edu

OnePieceADay (OPAD) is a proponent of plastic-free living. OnePieceADay is a mobile app where users log pollution they've either picked up or refused. OPAD was created as a global initiative to raise awareness on the detrimental effects of plastic pollution on the planet. They believe the proliferation of single-use plastic is the biggest contributor towards climate change. The goal with OPAD is to raise awareness of plastic pollution and in effect, eliminate the demand for singleuse plastics. Most recently, OPAD launched an eco e-commerce shop to encourage the world to integrate sustainability into everyday living.

A small energy harvesting device that can transform subtle mechanical vibrations into electrical energy could be used to power wireless sensors and actuators for use in anything from temperature and occupancy monitoring in smart environments, to biosensing within the human body. In research recently published online in the Journal of Micromechanics and Microengineering, engineers at Rensselaer Polytechnic Institute developed a predictive model for such a device, which will allow researchers to better understand and optimize its functionalities, and eventually these harvesters will replace batteries, reducing associated environmentally hazardous waste and maintenance costs.

Investment in Human Skills Alongside Digitalization Essential to Optimizing Wind Projects by Rakesh Maharaj

THE US WIND SECTOR HAS SEEN REMARKABLE

growth in the last five years, increasing from almost 75GW of installed capacity in 2015, to over 105GW at the end of 2019. But with growth comes growing pains. While the Production Tax Credit has fueled expansion by providing developers and manufacturers with the confidence to make longer-term investment decisions, it has also forced companies throughout the value chain to drive down their costs. Owners, operators, and contractors have all faced the same central challenge: find more from less. The result is twofold… First, the drive for efficiency has led the wind industry to embrace digitalization in the form of remote monitoring, predictive maintenance, machine learning and more. A majority of companies continue to invest heavily in the use of digital technology to optimize mechanical assets. Second, labor costs have been trimmed at the expense of talent development. Recent reports suggest that, despite the boom of the last five years, US wind now faces a shortfall of qualified technicians that can construct and maintain wind turbines safely. Amid growing pressure to run leaner projects, operators look at ways to increase profit margins primarily through investment in digitalization, not human skills. Indeed, companies are often more concerned with finding ways to design humans out of their processes – via artificial intelligence and automation – than improving the skills of the individuals at all levels in their teams. However, until manufacturers develop self-inspecting, self-repairing, and self-managing assets, humans will remain a vital part of the industry. Making sense of asset data - and how it translates into work activity - is where optimized human intelligence and informed decision-making remains a necessity, something that many companies, unfortunately, continue to overlook. Optimized human performance can also act as a catalyst for enhanced asset performance, as well as deliver increased availability, less turbine downtime, safer colleagues, and fewer organizational siloes. With Joe Biden planning to invest $400 billion into clean energy over the next decade, the US wind sector needs to recognize that investment in human performance, alongside continued investment in digitalization, represents the route to safer and fully optimized projects. In fact, this philosophy was recently field-tested1 with a number of European industry leaders.

The Great Leap Forward

Traditional training models in the wind sector have focused primarily on developing skills in a classroom setting. While that class time is valuable, remembering ‘book knowledge’ months or years after learning it can pose a problem in the course of on-site work. What’s more, increasingly overstretched teams were already struggling to spare resource to offsite training, even before the emergence of Covid-19.

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

There had to be a better way. Readers of Harvard Business Review will be familiar with the concept of ‘workflow learning’. In February 2019, the publication argued that the best way to help workers learn the skills they need for day-to-day work is to ensure that their learning fits around the working day. The wind industry can benefit from this approach, where a digital performance support platform helps wind professionals learn vital skills during the daily flow of their work. From project manager to lead technician, personnel in a wide range of key roles can have touch-of-abutton access to the knowledge and good practice they need in order to keep projects safe and productive. Because the performance and decision-making of humans are every bit as important as technology to the safety and financial performance of projects, it’s a way of using that technology to improve the daily decisions taken at all stages of the project life cycle. Early adopters of this methodology are encouraged by how much digital performance support can help the wind industry further reduce levelized costs, in both construction and operation.

Five more years

As the US wind industry begins to chase down another five years of growth, we shouldn’t overlook the human contribution to portfolio productivity. Digital performance support represents an essential new approach to skills development that fits, hand-in-glove, with the challenges the global wind industry itself acknowledges. It presents an end to decision-making in a void. And it places human performance back alongside digitalization at the heart of the push to optimize assets.

Lidar Data Fix for Complex Terrain by Juan Camilo Daza

Lidar devices are being used more and more to conduct wind resource assessment, as an alternative to meteorological masts. This is because they have several advantages over the traditional measuring technology. Once a meteorological mast is installed, both the position and height of conventional anemometers are fixed, therefore limiting the measurements to certain locations and heights; Lidars easily overcome this inconvenience with their inherent portability. Lidars can also measure wind speeds at greater heights than most meteorological masts. Given increasing onshore wind turbine heights - and rotor diameters reaching upwards of 525 feet (160 meters) - this ability is crucial. Ground-based, vertically-scanning Lidars calculate the wind speed VC based on measurements performed on a circular scanned area (as seen in Figure 1). The Lidar measures VU and VD. This area has a diameter size close to the size of the measured height.

Therefore, θ, VD, VU, φD and φU must be obtained. θ is easily obtained: it is simply the half cone scan angle of the specific Lidar being used. On the other hand, an accurate wind flow model is required to obtain both the wind speeds (VD and VU) and the inflow angles (φD and φU). Therefore, the correction factor is:

α=VL/VC

• VC: Calculated wind speed at the center • VU: Measured wind speed upwind • VD: Measured wind speed downwind • VL : Corrected wind speed • θ: Half cone scan angle • φU: Upwind inflow angle • φD: Downwind inflow angle Figure 1. Figure 1: The Lidar cone scan The calculation for the wind speed VC assumes that the flow over the measurement circle is homogeneous, and therefore that φU=φD and consequently that VC=(VU+VD)/2. However, this assumption breaks down when the flow is non-uniform, which is typical for a non-simple terrain. What is desired is the corrected wind speed VL. According to Sanquer et al. (Sanquer & Woodward, 2016) the general equation for VL is:

VL=1/(2 sin θ ) [VD sin(θ+φD) + VU sin(θ-φ_U )]

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

For the accurate acquirement of wind speeds and inflow angles, flow features typical of non-simple terrain, such as separation and recirculation, must be modeled accurately. Using a wind flow model such as Computational Fluid Dynamics (CFD), it is possible to compute the set of factors so that the correction of Lidar result data is similar to what’s measured by a conventional anemometer at the point of interest,

directly above the measuring device (Bingöl, Mann, & Foussekis, 2009). Sanquer et al. (Sanquer & Woodward, 2016) used CFD to solve the Reynolds Averaged Navier-Stokes (RANS) equations to compute the required wind speeds and inflow angles. This method solves the RANS equations in a refined mesh around the Lidar location, hence obtaining the wind speeds and inflow angles at the desired locations. Non-simple terrains will induce flow distortion, causing φU to be different than φD. This makes it extremely important to determine which types of terrain are not simple ones. The complexity of terrain may be determined by using the ruggedness index, as described by both Berge et al. (Berge, Nyhammer, Tallhaug, & Jacobsen, 2006) and Bowen et al. (Bowen

& Mortensen, 1996). The ruggedness index is defined as the fractional area of a terrain in the circular vicinity of a point of interest which exceeds a critical slope. However, applying the ruggedness index means having to select the critical slope; additionally, forest influences on the wind flow are not considered. The relationship between WAsP prediction errors and site ruggedness has been explored by Mortensen et al. (Mortensen, Tindal, & Landberg, 2008). Taking into account these references, it is best to follow Bingöl (Bingöl F. , 2010), which proposes a classification for the complexity of a site based on the following categories: - Flat terrain - Moderately complex terrain (hilly or vegetated) - Complex terrain (mountains or forests) - Highly complex terrain (any combination of moderately complex and complex site characteristics) Sanquer et al. (Sanquer & Woodward, 2016) tested this method on eight different sites of varying complexity. The results of that testing concluded that applying the CFD correction to data from Lidars in complex terrain improves the agreement between wind speed measurements from Lidars and meteorological masts. Additionally, for moderately complex terrain and complex terrain, the CFD correction of Lidar result data should be a standard process.

The Nearness of Wind by Kevin Wolf

WHAT DO YOU THINK OF WHEN YOU HEAR

the wind blow? Or see clouds flying across the sky? If you ask most people about capturing the power of wind, they picture a towering wind turbine. In fact, the clean energy industry may be missing out on an oft-ignored resource: low-lying winds.

Reintroducing H-type turbines

H-type turbines are compact, ground-level wind turbines that have been around for decades. By placing these relatively short turbines in the “understory” of tall turbines, an estimated 20 percent of wind farms can profitably capture the energy of near-ground winds. Traditional turbines do not do well in turbulent conditions. Gusts shake the blades that attach to these turbines’ horizontally-aligned drivetrains. Shaking causes the bearings in the drive shafts and generators to wear out; repairing these can be hugely expensive. Thus, propeller-type turbines are placed far apart from one another and high above the near-ground turbulent wind layer so that they realize smooth, laminar wind flow through the entire sweep of their long blades. H-type turbines, with their two or more arms connecting to each blade and vertically-aligned drive trains, are inherently able to do well in turbulence. Siting these vertically-spinning turbines as close

as a few feet apart from one another produces what is known as the Coupled Vortex Effect: the wind speeds up in the gap, creating more lift on the neighboring blades while the vortexes in the wake lower the pressure downwind, accelerating the wind through the entire rotor. With this, the density of energy production from wind-rich land can increase significantly. As a result, wind farms have the potential to expand renewable energy and lower the cost of electricity. Though H-type prototypes are not new, validation of their design concepts is new. Aeroelastic models are now able to predict fatigue, harmonic frequencies, structural integrity, and the aerodynamics of these turbines. And, thanks to a grant from the California Energy Commission, computer modeling also reveals how well the Coupled Vortex Effect compensates for the problem of drag from vertically-aligned turbines. Adding to the logic of developing the understory is research by several professors, including Drs. John Dabiri of Caltech and Marius Parschivoiu of Concordia University. Their studies show that pairs of closely spaced, compact H-type turbines can cause fast-moving, higher altitude winds to flow downward and nearer to the ground. The energy in the wind is measured as the cube of the wind speed, so even small increases in speed through tall turbine rotors create a marked rise in energy output. The result: more energy and greater efficiency. By precisely placing H-type turbines in the shadows of traditional wind turbines, the models indicate that fields of them will be able to produce a lot more energy than previously thought possible from windy lands. For example, advanced computer software was used to estimate near-ground wind speeds in 40 percent of the wind farms around the world. Based on extrapolating the results to all the wind farms, an estimated 100,000 megawatts of existing wind farms will have average annual wind speeds between 15 and 20 miles per hour, at 3080 feet above the ground. Pairs of H-type turbines in these locations should realize 30-50 percent capacity factors; and double or more the energy output from these properties. Because existing wind farms are already zoned for turbines with access roads, fencing, and other infrastructure in place, adding an understory of H-type turbines will realize much lower costs than projects built on raw land. This is especially true if nearground turbines come with batteries, so the wind farm's substation and transmission lines do not have to increase in capacity and size. Economies of scale will also lower manufacturing and installation costs

Sealing mastic for service entries and ducts for H-type turbines. As a result, supply chains will become more competitive, while advances in technology will continue to make wind power more affordable. Building out existing wind farms will also become less expensive as construction costs and up-front expenses decline. Reductions in balance-of-plant costs on a per megawatt basis will become clear. These trends will expand, as H-type turbines go from pilot projects to full-scale deployment among all wind farms with an ample supply of near-ground winds. All of these things are not only doable, but practical in the short-term. From tax collectors to wind farm owners and operators to entrepreneurs, building out the understory of wind farms offers a windfall (pun intended) for everyone. Both public and private institutions can benefit from this new and profitable source of energy; benefits that are all the more important right now, as the industry continues to struggle with the economic challenges of COVID-19. We would be remiss if we were to delay this opportunity to deliver a new source of reliable, clean, inexpensive, and renewable energy. The good we can do is considerable. The winds of renewal are real, impressive, and accessible. For these reasons, we choose to champion a cause that is beneficial to all and harmful to none. We choose to seize the high ground by gathering the rewards nearer to the ground. We choose to direct our energy at harvesting near-ground winds.

Kevin Wolf is CEO and a cofounder of Wind Harvest, which designs turbines that can use highly energetic near-ground wind.

Port of Opportunity

Lake Charles, anchor of oil-and-gas country, also helps advance renewable energy in America by Brett Downer

Wind turbine blades are a major cargo at the Port of Lake Charles, which handles the components after they enter Louisiana’s coast from the Gulf of Mexico and head up the Calcasieu Ship Channel. After a long tradition of serving as a national oil-and-gas corridor, Louisiana’s Port of Lake Charles has taken on a new role: serving America’s power-generation future. The biggest change? The arrival of huge new cargo items that can make even the more seasoned longshore workers stop and stare. They are, of course, the giant blades needed to power the wind turbines for one of the nation’s booming renewable power sources: wind energy. It’s an item that many ports aren’t able to move, yet the Port of Lake Charles now handles shipments of these blades with growing regularity. It’s the latest example of how Lake Charles can handle cargo that’s beyond the capabilities of other ports. The Port of Lake Charles now handles more than 900 blades annually. Last year, it added tower components — three sections, 80 tons each, that are assembled into towers upon reaching their destination. It’s a swift evolution from handling 591 blades in the inaugural year in 2019. It’s also testament to the ability to grow wind turbine business even in a crisis. Louisiana was hit by Hurricane Laura, its strongest storm in 150 years, and Lake Charles took a direct hit. The Port of Charles sustained multimillion-dollar damage, yet resumed operations, including the handling of blades, within a week of the storm.

With a strong focus on quality to ensure exceptional results; OEM's, project developers and supply companies can rely on TP&L's full-service logistics platform and limitless integration to manage the supply chain with increased efficiency and functionality.

Wind turbine blades arriving at the Port of Lake Charles measure 144 feet long and weigh about 11 tons each. The sizes vary, but they’re all massive — so they require considerable space for handling when they arrive at the Port. Once dockside, the blades are carefully unloaded at the port’s City Docks, where general breakbulk cargo is handled. The handling of the blades shows how the port moves cargoes that have ever-more-specialized shipping demands. For example, one recent load of blades was shipped out by Port Rail (the on-site short line railroad) after arriving at Berth 2 of the City Docks. For each load, the blades are placed on special double-length rail cars for delivery (think of big-city buses that flex in the middle to handle turns). From there, they are carefully moved by train or truck to destinations inland. One destination of these blades was a wind farm in Iowa, a state which generates 40 percent of its power from wind — the highest rate in the nation. Other blades went to Texas, which currently leads the U.S. in wind-power capacity. Once delivered, the blades are assembled onto a power generator atop a steel tower which reaches nearly half the height of the Eiffel Tower. These towering, powergenerating machines increasingly dot the landscape of the American homeland. The unusually large components are also a frequent and eye-catching sight by motorists in Lake Charles during local commutes that intersect the rail route.

Looking Ahead

The Port's future-minded capabilities for handling specialty breakbulk and project cargoes continue to gain local, national, and global attention. Nicknamed “America’s Energy Corridor,” the Calcasieu Ship Channel at Lake Charles boasts a nearly century-long history, during which it has served the lumber, rice, petrochemical, and LNG industries. It continues serving these sectors, along with the additional capacity to handle the specialized equipment necessary to expand wind power across the country. Renewable energy is a new and major area of growth for the facility. Part of a $200 million capital improvement plan spanning five years, the demolition of two antiquated warehouses, and the expansion of a rail yard to its City Docks facilities in 2018, the Port of Lake Charles is currently able to accept the leviathan components and blades that America’s wind industry demands. This year, the Port of Lake Charles will handle even larger blades and tower components. This growth bodes well for a port that’s a fixture in America’s traditional oilpatch, and a renewed gateway to its greener energy future.

The Special Cabling Challenges of Floating Offshore Wind Farms by Maxime Toulotte

OFFSHORE WIND FARMS ARE

recognized globally as an increasingly popular source of cost-effective and dependable renewable energy. In the United States, while turbines have already started to generate 30 MW from the strong winds off the east coast, additional legislation - in line with state carbon emission mandates - will bring this to a total of 25 GW within the next decade. Current offshore wind farm technology is limited to regions that have strong and steady winds with extended outer continental shelves, such as the eastern seaboard. For these projects, fixed-foundation offshore wind turbines arrays are anchored to the sea floor (around 150- to 200-feet deep). The power generated by the turbines flows through buried medium voltage submarine cables (called array or inter-array cables), to one or more offshore substations. From there, the pooled green energy is sent to shore via high voltage ‘export’ power cables. For offshore wind farms in less hospitable environments, such as where the ocean floor drops steeply close to shore and/or the required strong wind is very distant, an alternative approach is required. Enter “floating” wind farms. This technology involves wind turbines and offshore substations that are not bottom-fixed to the ocean floor, but rather placed on floating structures that are anchored to the seabed. The good news is that the development of floating offshore wind farms in the U.S., like that for fixedfoundation offshore wind, will benefit greatly from projects already underway in UK, Portugal, Norway, Spain, and Japan.

Advanced Dynamic Cables

Exporting energy from floating offshore wind farms requires the development of a new generation of export cables - the unseen, yet indispensable vehicles for the delivery of energy to shore. Unlike those for bottom-fixed offshore wind farms, these cables will be subject to additional variables such as hydrodynamic effects induced by waves and currents, the movements of the floating platforms in relation to the bottom of the ocean, and the effect of their own weight. So far, the needs have been met with dynamic cables rated at 34.5kV and 66kV using wet insulation designs that are similar to array

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

cables and other elements used in umbilicals for the oil and gas industry. However, these designs will not work for the export cables needed for utility scale, floating offshore wind farms, will need to carry far more power at a much higher voltage. The mechanical strength and fatigue property requirements for large floating wind farm cables far exceed those for export cables used with bottom-fixed offshore wind farms. One challenge lies in the use of lead sheaths. While they protect the export cables’ insulation from humidity and water penetration, they have limited metal fatigue properties when subject to constant movements. Another challenge for floating wind farm export cables is their weight. For a given weight per foot, the cable will break beyond a certain depth at the point where it is hanging. Different technological improvements are being developed for extending the range of the wet insulation design to the 115kV voltage class. Researchers are also working on finding ways to create water barriers (such as using alternative metallic alloy foil between the cables’ insulation and the jacket for higher voltage classes).

The (Very Near) Future of Floating Offshore Wind

The Carbon Trust (2020) reported that the global aspiration for floating wind could reach 10.7 GW by 2030, and up to 34 GW by 2035. This assumes that favorable policies in key floating markets (including the U.S.) will enable the transition to additional commercial-scale projects. In addition, it is widely believed among wind industry experts that the cost difference between bottom-fixed and floating offshore wind farms will become negligible in the coming years, thus eliminating a major hurdle. With the technologies rapidly evolving, floating offshore wind farms will become economically and logistically viable. This in turn should unlock their market potential, and help countries around the world realize a cost-effective and carbon-neutral way to solve their growing energy needs.

Maxime Toulotte is Nexans’ Head of Technical Marketing for its Subsea and Land Systems Business Group.

Nexans /// www.nexans.com Whatever the solution, it would have to work over long distances and remain sturdy and flexible enough not to break under the stress of constant movement. OEM engineers will need to understand and predict the lifetime of the different cable components, considering operational loading and environmental conditions. Testing and modeling will be necessary to account for fatigue, corrosion, and delamination, as well as to identify the materials that can bypass common failure scenarios. The next innovation in HV submarine cable technology will require a holistic engineering approach, as any structural changes to known designs will affect other properties of the cable system. The opportunities to develop offshore wind farms has reached U.S. shores, and momentum among the states will continue to grow as Americans become accustomed to seeing turbines off their coasts - and appreciate the clean energy benefits they provide. In the not so distant future, floating offshore wind farms will become part of the equation.

Canada’s New Wind Turbine Database by Ryan Kilpatrick and Thomas Levy

Canada has just released a wind energy database that will improve access to centralized, credible and publicly available energy data in Canada. The Canadian Wind Turbine Database (CWTDB)1 contains the locations of Canada’s approximately 6,500 wind turbines, including key data for researchers. The role of data in clean energy technology advancement

Light when you need it Aircraft Detection Lighting Systems

Data is the currency of the digital age. While this may sound like a cliché, the fact is that high quality and reliable data is universally valued in the 21st century. Renewable energy, including wind, is a key pillar in Canada’s transition to low-carbon energy systems and meeting its greenhouse gas reduction targets.2 More research is needed, however, to fuel the innovation necessary to achieve these goals. This may come in the form of developing new energy generation and storage technologies, deploying existing technologies and integrating them into power systems, or determining how to minimize negative ecological impacts. Underpinning all of this research and development is accurate, granular, and accessible data. Open-access data is invaluable to the research community – it enables transparency and repeatability, and leads to improved credibility and relevance of research findings. For example, grid integration studies such as the Pan-Canadian Wind Integration Study (PCWIS)3 and North American Renewable Integration Study (NARIS)4, rely on granular electricity data. When studies of this magnitude (involving large-scale models of electricity systems) significant effort and cost is devoted to building synthetic high-frequency datasets that serve as a proxy in the absence of actual load and generator production data. This prodigious effort could be minimized - or even avoided - through comprehensive and publicly available national electricity datasets.

Adding to Canada’s energy data landscape

The Government of Canada’s Directive on Open Government5 seeks to ensure that open data and open information is released in accessible and reusable formats. Canada has a long and distinguished history of making data accessible for its citizens, whether through Statistics Canada6, the Canada Energy Regulator7 (formerly the National Energy Board), or the expansive Open Maps8 platform. More recently, the Government of Canada has launched the Canadian Centre for Energy Information (CCEI)9, which aims to provide “a convenient one-stop virtual shop for independent and trusted information on energy in Canada.” The CCEI provides insight into “all things energy-related, including production, consumption, international trade and much more.” The new Canadian Wind Turbine Database continues Canada’s longstanding tradition of sharing information for the greater good.

A single, national-scale wind energy location dataset

In June 2020, Natural Resources Canada, together with the University of Alberta, released the CWTDB10. This extensive database can be found on the Government of Canada’s Open Government portal11, and provides static information on individual wind turbine

The CWTDB is the first comprehensive openaccess database for wind turbines across Canada, and follows similar efforts by other jurisdictions, including the United States, which released the U.S. Wind Turbine Database12 in 2018. The CWTDB is the result of a collaborative effort between CanmetENERGY Ottawa and the University of Alberta’s Centre for Applied Business Research in Energy and the Environment (CABREE)13. Key features of the new CWTDB include an interactive map14 of more than 6,500 individual wind turbines in Canada. The map lists their coordinates as well as key specifications including capacity, model, manufacturer, hub height, rotor diameter, and commissioning date. The database will continue to expand as it’s updated at least annually to reflect the construction of new wind farms. Centralizing information on individual wind turbines allows users to do research and modeling from an energy, environmental or economic perspective. The database can support R&D in sectors including natural resources, agriculture, and health. It is an example of CanmetENERGY Ottawa’s ongoing efforts to provide information to Canadians on clean energy, help integrate renewable energy into Canada’s provincial electrical grids, and address barriers to a wider deployment of renewable energy.

Valley Forge & Bolt’s RTM (Remote Tension Monitoring) series of meters, the UHF Band RTM Meter, is a wireless bolt monitoring system. The UHF Band RTM Meter operates in 433/868/915 MHz frequencies, which includes the industrial, scientific, and medical (ISM) frequency. This wireless sensor detects and collects the tension level in a bolted joint as read by the company’s SPC4 fastener, and then relays the data to a facility’s condition monitoring/SCADA system. Users can also program the sensor to take measurements at prescribed intervals and send alerts if a bolted joint falls out of chosen tension parameters. The meter facilitates close monitoring of new fasteners during and immediately after install. In the long term, all bolts can be set to broadcast alerts when a chosen tension threshold is crossed. Managers can also program alert windows during “interest” periods, such as times of suspected greater vibration in a process, to gauge how fasteners are reacting. With a web-based user interface, users can change parameters for each wireless sensor remotely. In addition, the UHF band attribute will improve battery life and enable increased distance from the probe to the collection device. SPC4 fasteners make it possible to measure the actual tension from within a fastener, providing real-time knowledge of critical joint tension and performance from installation through fastener life. A variety of sensors and meters are available to read, display, and relay this tension information.

them for miles. From high above, they look like a row of stitches. At a single upstate New York wind farm, there are dozens of wind turbines spanning thousands of acres. Atop a 500-foot tower, massive 144-foot blades turn, fitted on a huge hub turning a generator in a box the size of a city bus, weighing 60 tons. On a good day, they each produce enough electricity to power 3000 average homes. Yet few Americans ever get a glimpse of these massive engineering marvels. Wind turbines are typically located far from population centers—in this case, 300 miles from New York City, hungry for power for its 8.3 million citizens and their millions of lights, TVs, air conditioners, appliances, industrial machines, phones, PCs, and electronic devices. There’s only one way to get all this wind energy into the five boroughs: high-voltage transmission lines that stretch across the landscape, held aloft by 150-ft towers. There are more than 200,000 miles of these lines across the country. Not only is this a remarkable planning achievement, it also happens to be the “backbone” of the grid, the largest machine on earth. Unfortunately, this base of our infrastructure is showing its age: many parts of it are 50 years old or more. A reliable and adaptable electric grid can be the difference between a comfortable life or living in the middle ages. To wit: On a hot afternoon in August 2003, traffic lights and Broadway theaters went dark, air conditioners died, and crowded elevators and subway cars jerked to a halt, trapping their inhabitants inside across the nation’s largest city. Yet, nothing had happened in New York City to cause this. In fact, a hundred miles away in Ohio, overloaded high-voltage power lines sagged onto tree branches, and (compounded by operator errors and software failures) cascaded into a blackout that ran north to Ontario, Michigan, and Massachusetts; south to Maryland; and east to Connecticut. By the time it was restored, tens of millions of people had been seriously inconvenienced, many were put in actual danger, and hundreds of millions of dollars in economic value had simply evaporated. Moving power from generating stations to its consumers is no simple task; it is limited by several factors, including transmission line stability and the line’s thermal limits. When the amount of power flowing on the line reaches that limit, the line is said

to be “congested”. Then the system operator – in this case the PJM Regional Transmission Operator in the mid-Atlantic - must manage that congestion by one or more steps: They must take specific sources and amounts of generation offline (called “curtailment”); turn on more conveniently located but more expensive sources of generation (called “redispatch”); reroute power to other lines by switching; or shedding load (brownouts or blackouts) In other words, the capacity and flexibility of transmission lines are paramount to a reliable and efficient grid. Going forward, this becomes even more important. Utility-scale terrestrial wind farms, offshore wind parks, and solar resources are increasingly added to the grid’s energy supply. More distributed energy resources including home, commercial and community solar will come online. Electric vehicles and their charging stations will continue to proliferate. In many places, the system is already stretched to capacity. One wind company CEO sums up the concerns of renewables operators like this: “For wind farm owners with neighboring projects, windy days can be

a mixed blessing: ‘great, your wind farm is producing more energy’; but bad because the line is congested and can’t transmit all the energy from the competing wind farms. Any solution that can alleviate the transmission constraint could be money in the pockets of the project owners.” Why don’t we just build more transmission lines? This might seem to be a simple answer, and new lines are needed. But these can take years to build, and require an elaborate (and lengthy) series of studies, permits, and approvals by both federal and state regulatory agencies. The costs can be enormous, and are often borne by consumers in the places where they’re built. And, as crazy as it may sound, some won’t be built at all due to community opposition, or NIMBY (“Not In My Back Yard”). Fortunately, there are solutions that don’t require complex, expensive, time consuming—and unlikely— new construction. Existing sensor technologies are able to safely unlock up to an additional 40 percent capacity on the current system. This is done by moving from highly conservative static ratings, to Dynamic Line Ratings (DLR), which take advantage of sensor data on the actual capacity of the line. By deploying this grid-enhancing technology, not only can we utilize more of the existing renewable energy sources, but we can look to reduce the need, time required, or cost to construct network upgrades that may have been specified as prerequisites to interconnect new sources of renewable generation. In addition to increased capacity, these technologies offer other important benefits like Asset Health Monitoring. This type of monitoring checks and evaluates the overall condition of transmission lines, helps identify problems before they occur, and improves the utility’s ability to forecast when maintenance or replacement is required. Think of it as preventative healthcare for the grid. A Situational Awareness system that monitors and alerts for specific behavior of conductors

like icing, side to side swaying, excess sagging, or “galloping” in the wind (which can result in conductors touching each other or touching tree branches, literally energizing the tree and - in all cases - taking the circuit offline, and putting safety at risk). These systems are non-invasive and non-contact, meaning that they can be installed and operated without taking the lines out of service. It really works. One recent system installation on transmission lines in the southwest United States revealed that there was often additional capacity available above the static rating when the line was experiencing congestion. An analysis by the grid operator SPP showed that the congestion was unnecessary, and the line could operate safely while carrying additional current. During the following four months of monitoring, the Dynamic Line Rating showed that, for 99.9 percent of the time, there was additional capacity above the line’s static rating. Every day we rely on our power grid to be there for us. With each new technology we develop, we place an increasing burden on that grid. It’s more important than ever that we take full advantage of its capacity and resiliency with advanced transmission technologies like Dynamic Line Ratings, so we can keep moving toward a cleaner energy economy (while still keeping the lights on).

Louisiana

Ready to thrive in transition to clean energy by Pierre Conner

During the final presidential debate in October, former Vice President Joe Biden ignited a storm of controversy when he called for the U.S. to transition away from oil and gas to clean energy sources. Given the large role oil and gas plays in Louisiana’s economy, many people here reacted with alarm, fearing that a Biden administration would hasten the demise of an industry that’s been almost synonymous with the state for over 100 years. As with most political rhetoric, however, the noise tended to drown out the underlying truth: Louisiana has been anticipating and preparing for the transition to clean energy for a number of years now, and the shift could actually end up benefitting the state in the long run. In fact, thanks in large part to the infrastructure built to support oil and gas, Louisiana is uniquely well positioned to move from strength to strength in energy production during the transition to lower carbon sources and uses. Louisiana’s history as an innovator in oil and gas development goes back many years. The nation’s first oil well out of sight from land was drilled in Louisiana’s Ship Shoal area in 1947, and the offshore oil industry took off from there. Exploiting its location on the Gulf of Mexico and at the mouth of the Mississippi River, Louisiana leveraged that geographical advantage by developing ports, an extensive pipeline network, and a highly skilled workforce. At the same time, independent companies developed a host of offshore support services - everything from construction and transportation to industrial operations and maintenance. Over the next several decades, Louisiana pushed those technologies around the world, exporting innovations that were developed in the bayous of South Louisiana, all the way to Europe, Africa, and Asia.

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

Although Louisiana is not currently leading the charge on renewable energy, its history of innovation in oil and gas suggests it has the potential to climb the ranks. Significantly, the state has already begun to actively prepare for the transition to clean energy. In August 2020, Louisiana Gov. John Bel Edwards established the Climate Initiatives Task Force to investigate strategies to reduce Louisiana’s greenhouse gas footprint by 26 to 28 percent by 2025, all the way to net zero by 2050. A cross section of the state will be represented on the task force and related advisory groups and committees, assisted by Tulane University. As we see it, there are multiple pathways for making progress in decarbonization in the state, including carbon sequestration, decarbonization of industrial processes, integration to a hydrogen economy, and acting as a focal point for the development of offshore wind power in the Gulf of Mexico. CO2 emissions in Louisiana are relatively concentrated compared to other locations, because its industrial footprint tends to emit high purity CO2 from point sources (as opposed to distributed emissions such as in transportation). One solution this lends itself to is carbon sequestration. A study by our partners at Louisiana State University points out that Louisiana has a “Saudi Arabia” of pore space, and can leverage its onshore and nearshore depleted hydrocarbon reservoirs to accept CO2 emissions for permanent storage. The concentrated point source discharge of CO2 also contributes to the “U” of CCUS. There are initiatives under consideration already, but we envision the leveraging of longestablished chemical processes to utilize this CO2 in a positive way. For example, the Sabatier reaction can be used to methanize green hydrogen with point source CO2 emissions that would have otherwise been discharged, to create net carbon neutral methane. Green methane can be used for local power generation, and is well suited to mesh with intermittent generation of wind or solar PV electric power. Additional well-established chemical processes can tie up CO2 into stable compounds for other uses as well. Due to its position on the Gulf of Mexico and ready access to the Mississippi River’s cost-effective transportation system, Louisiana has become the nexus of the vast network of pipelines for both import/export and hydrocarbon processing. The state can leverage this infrastructure to its advantage as it transitions to lower carbon

and commercial power demand as the East Coast, Louisiana still has significant industrial demand. Importantly, if wind power can be combined with the concepts of hydrogen production from renewable power, that would bode well for the future. With some forethought and adjustments, Louisiana has the oil and gas supply chain and infrastructure to support construction, installation, and operation of offshore wind from local shipyards, fab yards, bases, and ports. If Louisiana is to become a leader in clean industrial processes, and renewable and sustainable energy, the state will need everyone involved to help put the pieces of this puzzle together. The Tulane Energy Institute, within Tulane University’s A. B. Freeman School of Business, is committed to being a part of this transformation. We are currently working with industry partners across the spectrum of energy production, transportation, and consumption, to discover ways to make the changes needed and generate net positive business impacts. In addition, through curricular offerings such as our Master of Management in Energy (MME) program’s Specialization in Renewable and Sustainable Energy, we are preparing the next generation of energy business professionals to take on the challenges of clean energy generation. With a great deal of work and commitment, Louisiana has the potential to become a leader in clean energy.

Less weight, low collapsed height, fast retraction

The new Enerpac RARH series of cylinders are designed for challenging projects and include tough aluminum construction which provides a low weight solution. Performance and durability are not compromised by their reduced weight, with each cylinder meeting ASME B30.1 standard and incorporating a built-in safety valve to prevent over-pressurization. Getting the cylinders into position and into smaller spaces is assisted by the integral handles on each model and their lower collapsed height. The RARH cylinders are doubleacting, which means heavy loads can be lifted and lowered with precise control. A double-acting cylinder outputs force both in and out, creating a high control level for the retraction that is reliable, fast, and easy to control. The cylinder can be retracted efficiently. Available now are 30 and 60 tonnage cylinders (each available with a stroke choice of 50, 150, and 250mm [1.97", 5.91”, and 9.84") with more models coming soon.

Circuit breaker for the renewable energy market

Siemens has introduced the type SDV-R non-arc-resistant and type SDV-R-AR arc-resistant medium-voltage outdoor distribution circuit breakers designed specifically for renewable energy applications, such as wind power generation. These newest members of the reliable Siemens SDV distribution circuit breaker family now provide fast switching to ground, ultimately saving money and space through an environmentally friendly solution. The integral fast-acting grounding switch, which is mechanically interlocked with the SDV-R circuit breakers, helps limit transient voltage excursions (inherent to collection systems) to very low levels during switching operations. This feature offers wind power producers an alternative to large, expensive grounding transformers with cable connections that take up significant space and pose environmental risks associated with oil leaks. To provide additional personal protection in the event of an internal arcing fault, the SDV-R-AR circuit breakers have been qualified to carry a type 2B accessibility rating in accordance with the latest ANSI/IEEE C37.20.7 standard. This is the same qualification approach implemented in the type SDV7AR circuit breakers for the purpose of providing enhanced personal protection.

A Professional Buyer's Guide to Dependable Energy Storage by Wes Kennedy

ENERGY STORAGE HAS DOMINATED

conversations among solar professionals and the energy industry for the last several years. As traditional rules of Net Energy Metering slowly fade, energy storage is poised to become one of the most critical components to any renewable energy project. Currently, rate structures surrounding the simple buy/sell meter are no longer optimized to provide customers with the most value for their solar generation. Utilities have started charging customers for the times that their production capacities are nearing its limits; for customers, these charges appear either as momentary peak demand charges or hour-long stretches, typically in the afternoon and evening, when energy is purchased at premium Time-of-Use (TOU) rates. Since solar PV generates energy in a bell curve (peaking at noon when energy is cheapest) energy storage is the best option moving forward that gives customers the control to sell those clean solar electrons back to the grid at a premium value. With more companies offering energy storage solutions, the market has been flooded with an array of battery products, each one more different than the last. The question on every installerâ&#x20AC;&#x2122;s mind is: Which product to choose? The right battery selection is critical, especially for customers who demand the best. This includes those relying on batteries to support their entire energy load, as well as customers who have been burned in the past by entrylevel products or lead acid, and are now looking for the most sophisticated technology. Cities prone to weather-related power outages, like those in California and Puerto Rico, require reliable products to supply clean drinking water and maintain business continuity. Given that the majority of end customers know little about the differences between the batteries available to them, installers are tasked with recommending the solution that best suits their individual needs. To find the right fit, there are three key factors to take into consideration: safety, performance, and flexibility.

JANUARY â&#x20AC;˘ FEBRUARY2021 /// www.nacleanenergy.com

Battery Safety

First and foremost, it is essential to compare the safety of each battery, starting with its chemistry. Not all batteries are equally safe; saving the customer money on their electricity bill or lowering their carbon footprint will be of little value if the battery system introduces hazards to their home and the environment. While lead acid batteries require outside ventilation to avoid flammable and smelly off-gassing, some lithium chemistries - notably nickel cobalt aluminum (NCA) and nickel manganese cobalt (NMC) - suffer from potential thermal runaway issues when any part of the system fails. Unfortunately, each of these traits runs the risk of starting fires. Lithium ion batteries are among the most popular for energy storage, due in large part to high energy density, but the makeup of these batteries can vary tremendously. Lithium iron phosphate (LFP), for example, has proven to be a thermally stable choice for installers. It is made with materials that are intrinsically safer than other lithium ion batteries, which can give the customer peace-of-mind knowing that, even in the event of a fire, the battery valves will open to relieve pressure at the cell level. LFP is also cobalt-free, an added benefit that not only eliminates the need for expensive materials but also avoids the harsh consequences of cobalt mining, including child labor, the inhalation of toxic fumes, and fatality.

Durability and Longevity

The financial payback of a solar PV system hinges on long, hassle-free system performance. Again, knowing that not all batteries are created equal, recognizing the differences between battery maintenance will enable solar installers to provide customers with products that offer the highest return on investment. Lead acid batteries typically require monthly maintenance and five-year

replacement cycles, while NCA and NMC batteries typically last 10 years between replacement cycles. However, even those with 10-year replacement cycles can be riddled with exceptions. For example, some manufacturers limit the average depth-of-discharge while others discourage fully charging the battery. As a result, the end customer pays for a capacity that they have no way of fully utilizing. Some battery manufacturers even have strict requirements regarding internet connectivity, in which case a lost signal results in loss of full warranty coverage. The best option is to look for warranties allowing a 100 percent depth-of-discharge, and a minimum 15-year performance guarantee.

The market for battery storage will undoubtedly expand over the coming years, particularly as technology progresses and renewable energyâ&#x20AC;&#x2122;s integration with the electrical grid becomes more complex. Though changes in battery solutions are also imminent, there are a few features that will never go out of style - safety and stability, durability and capability, and flexibility in design and future use. When it comes to choosing which battery products to bring into the homes and businesses of customers, following these simple guidelines will help to future-proof your projects.

Blue Planet Energy /// blueplanetenergy.com

Flexibility

Because each customerâ&#x20AC;&#x2122;s energy needs are unique, a one-size-fits-all approach to battery storage can leave many customers with a system that fails to meet their expectations. Flexibility, in regards to both scalability and inverter compatibility, is the third and final piece to selecting the premier battery in the market. Using a battery that works with a wide variety of inverters enables installers to choose inverter partners that work best within their Balance of Systems, and opens the installer up to building the most optimized system for their customer. As customer needs evolve over time, flexibility also becomes a priority. Customers who initially purchased 8 kWh or 16 kWh of storage capacity may end up doubling their energy consumption, requiring twice the amount of storage. Not only does the installer need a battery that can integrate seamlessly with the existing batteries, but new batteries must be installed with limited space to scale. In places like garages or basements, where square-footage is smaller, expanding system size without compromising its footprint can be a challenge. Luckily, there are low-profile and even stackable batteries. The best strategy is to start with a battery designed specifically for flexibility to make accommodating future changes much easier.

Preventing Thermal Runaway Before It Begins by Steve Cummings

Utility, industrial, commercial, and government facilities are increasingly turning to Battery Energy Storage Systems (BESSs) - in a variety of sizes and power outputs - for reliable back-up power. This market is expected to exceed more than US $9 billion by 2024, at a compound annual growth rate of 34 percent. Given the expected growth in this sector, coupled with the fact that most BESSs are designed by interconnecting a series of Lithium-ion (Li-ion) batteries, the industry is continuing to focus attention on measures designed to practically eliminate any potential for dangerous thermal runaway conditions. Thermal runaway occurs when excess heat (caused by defects, mechanical failures from damage, or improper operation of the system) creates a reaction that further increases the temperature. If left unchecked by built-in system protections or a Battery Management System (BMS), this process continues to drive up temperature and pressure until the battery cell ruptures, which can spark fires in affected and adjacent cells. Fortunately, early detection systems have been developed that can now detect a unique pre-cursor event to thermal runaway: off-gassing in the battery cell that occurs up to 30 minutes prior to a cascading failure. This distinctive and recognizable early warning sign enables the problem to be mitigated - or the system shut down - before thermal runaway can even begin. Although virtually all quality BMS equipment monitors temperature and other variables to prevent thermal runaway by triggering protections, the early detection of off-gassing provides a critical additional layer of protection for the entire system, the facility, and even personnel.

Early detection

The early detection of thermal runaway relies on four sequential stages of Li-ion battery failure: 1. A Li-ion battery cell first begins to fail when it is subjected to an abuse factor like heat, overvoltage, etc., 2. The second stage is off-gassing 3. The third stage is smoke; 4. And the fourth stage is fire. But smoke and fire often occur simultaneously. In other words, by the time smoke is detected, thermal runaway has already begun. Off-gassing usually occurs due to a breakdown of a Li-ion battery cell electrolyte due to pressure buildup. Later, as temperature increases, smoke is emitted and fire breaks out. To enable off-gassing detection at the earliest stage of a battery event after the initial abuse, an early detection system offers a battery off-gas monitor and sensor network designed specifically for lithium ion batteries. Because the system can detect off-gassing at the ppm-level concentration range, it can recognize individual cell failures without contacting the cells; as soon as a single battery

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

cell begins to fail, the system can prevent thermal runaway and its spread to adjacent cells. The benefits of both Li-ion BESSs and Li-ion specific off-gas detection systems have prompted a growing number of facilities to install them together. Microgrids are small electrical systems that can operate both independently and together with the larger local electrical grid. They are being increasingly deployed at critical, nonmilitary facilities such as hospitals, fire stations, and airports to provide uninterrupted power during local electric utility outages. Last year, the U.S. Navy contracted out for the design and building of two transportable microgrid BESSs. The project was funded in part through the California Energy Commission’s Electric Program Investment Charge (EPIC) program, and the Department of Defense’s Environmental Security Technology Certification. In the Navy’s case, the microgrid will use solar energy. The BESS, along with Navy site generation, will provide emergency backup for blackout recovery, disaster recovery, and weather/fire/storm response. Each BESS is lithium-ion based and can deliver 250kW of power on demand. Both will go through testing at the Port Hueneme Naval Base in Ventura County, CA. Afterwards, they will then go through testing and operational use at a Naval Surface Warfare Center-Port Hueneme division data center in Southern California. Taking advantage of the latest in safety technology, a Navy-approved off-gas detection system will be built into the unit’s system supervisory controller as both a redundant safety solution and on-board fire protection/suppression system. A growing number of facilities are recognizing that, although a BMS can provide data and shut the BESS down, there are times when the BMS can miss critical indicators or malfunction. As a result, there is the need for a separate, redundant system that can indicate the potential for thermal runaway before it occurs so the BESS can be shut down to prevent it.

Steve Cummings is director of the sensors business unit at Nexceris, a developer of gas sensors and monitors. The company worked with the U.S. Navy a decade ago to develop an off-gassing detection technology for Li-ion BESSs that is compatible with all Li-ion chemistries.

Are Battery Metals the New Oil? by Ajay Kochhar

WHETHER STORING ENERGY FROM CARBON-NEUTRAL

energy sources, or powering electric vehicles and personal electronics, lithium-ion (li-ion) batteries and their materials are fueling the world. The rising demand for the metals and materials that go into creating these Li-ion batteries is backed up by the numbers; demand is set to increase more than ten-fold by 2029. While this potential growth points towards a positive shift away from carbon-based energy sources, the proliferation of the lithium-ion batteries presents major social and environmental implications that cannot be ignored. Furthermore, when these batteries reach the end of their life, they can potentially be extremely dangerous, and at least as ‘unclean’ as oil. Therefore, careful consideration must be taken to ensure that one harmful resource is not being exchanged for another.

Production

What exactly are the harmful implications of a li-ion battery dominant future? The most significant pitfall lies in the raw materials necessary for the production of these batteries. The primary materials used in li-ion batteries are lithium, cobalt, nickel, manganese, and graphite. Not only are these materials scattered throughout the

world, but they are heavily concentrated in countries where environmental and labor regulations are unclear or even non-existent, leaving the local populations vulnerable to exploitation and violence. The Democratic Republic of the Congo (DRC) is a prime example of this. The DRC accounts for almost two-thirds of the world’s supply of cobalt; according to a United Nations report, the mining processes in this area have been identified as dangerous, and involve the exploitation of child labor. Regarding the environment, any type of mining for raw material can result in erosion, sinkholes, loss of biodiversity, soil, groundwater, and surface water contamination. Not to mention the release of harmful carbon emissions from the considerable amount of energy involved in the mining process. Unfortunately, the continual extraction of these resources for battery production could result in a zero-sum game when compared with the extraction of crude oil: The volume of materials needed to produce one liion battery for an electric vehicle is equal to the materials required to create 15,000 cell phone batteries. The demand for more and more electric vehicles - and the li-ion batteries that power them - is rising exponentially.

A Potential for Harm

Just like with oil, as the utilization of the li-ion technology increases, these batteries will play a growing and critical role across a broad spectrum of industries like energy, automotive, and other forms of mobility. From the surface, limiting the use of crude oil and assisting in the reduction of carbon emissions appears to be a good thing. However, this doesn’t take into account the increased potential for these batteries to cause harm in the event they malfunction or are destroyed in an accident. While li-ion batteries are generally considered to be safe and stable, as with any technology, there is always the possibility of a malfunction or damage. In the case of li-ion, that means the release of gasses and electrolytes such as hydrogen fluoride, phosphoryl fluoride, and other combustion byproducts and organic solvents. These chemicals can be corrosive, toxic, and even flammable, with the potential to cause lasting harm to human life.

End of Life

As with most batteries, once li-ion batteries begin to fail, they are discarded, treated as waste, and end up in dumpsites. While this seems like the logical step in disposing of any spent material, it also raises the question: are we simply trading out the carbon emissions from oil for solid waste? Unfortunately, with the increasing volume of li-ion batteries ending up in landfills, this appears to be the case. In fact, analysts have stated that the amount of lithium-ion batteries expected to be available for recycling will grow from approximately 150,000 tons per year in 2020, to over 3,700,000 tons per year in 2030. On a cumulative basis, this translates to over 15 million tons of lithium-ion batteries available

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

We should not forget the positive impact oil has had on the world’s development and forward progression. Now, as battery prices continue to fall, it makes sense that li-ion batteries - and the components that make them - are quickly becoming ‘the new oil.’ Before li-ion batteries completely take the reins in providing the worlds’ electricity needs, it’s up to innovators to optimize recycling processes, and ensure that batteries don’t leave the same legacy of environmental destruction and social unrest as their predecessor.

for recycling by 2030. China alone will generate approximately half a million metric tons of spent Li-ion batteries in 2020; by 2030, this figure is set to reach 2 million metric tons of Li-ion waste per year. In an attempt to curb the amount of materials ending up in landfills, li-ion batteries have been predominantly moved around the world for re-use, or partially recycled via thermal processing: spent batteries are incinerated, resulting in typical crude resource recovery rates between 40 and 50 percent, with key elements like lithium being completely volatilized. This energy-intensive method produces a significant amount of both solid and gas waste. Not only is this process unsustainable in the long-term, but it will do little to satiate the growing demand for new Li-ion batteries necessary to sustain the transition to renewable energy and carbon-free transportation. There is a gap between the promise of li-ion batteries as an environmentallyconscious solution to carbon-based energy, and the reality of the situation that has inspired a number of companies to innovate new methods to transform li-ion battery to be a truly circular and sustainable product. One such technique relies on a closedloop system, where spent batteries are sent to resource recovery centers where through a process of mechanical shredding and hydrometallurgical/ wet chemistry. This innovative process successfully recovers ≥95 percent of critical materials in li-ion batteries, returning these materials back to the supply chain. This method completely changes the way in which li-ion batteries are treated at the end of their life cycle, potentially alleviating many of the negative impacts of raw material mining and production. Additionally, this closed-loop resource recovery method removes the need for extensive resource mining, reduces the amount of waste released into the atmosphere or sent to landfill, minimizes the amount of global shipping needed to transport resources and other product components, and preserves deposits of finite natural resources. Essentially, the development of this resource recovery method means that Li-ion batteries no longer mirror big oil’s negative effects, and people no longer need to be concerned about the amount of waste, or negative social impacts their batteries are generating.

Three Predictions for the Energy Storage Industry in 2021 by Ryan Brown

2020 has been a challenging year for everyone, and the energy industry has not been spared. The COVID-19 pandemic and resulting economic crisis have created several challenges specific to the clean energy sector, leading many to question whether or not the industry is on track to achieve the decarbonization required by climate change targets. Renewables are expected to expand roughly 50 percent by 2025. Corporate funding for energy efficiency, smart grids, batteries and energy storage has increased 75 percent this year, displaying a sense of continued confidence in the energy sector’s trajectory. Anticipating and addressing challenges will help keep this sector on track for achieving the world’s environmental goals. For the battery industry in particular, acknowledging and working around the shortage and supply chain issues of lithium-ion batteries will be key. Over the past decade, battery storage has revolutionized – leading to nextgeneration batteries becoming the gateway to a net-zero future. Lithium-ion batteries continue to dominate the market as the leading solution for EVs and electronics, but most industry analysts expect demand to far outstrip supply in the coming years. To create a sustainable future, the world needs safer, cheaper, and more reliable batteries, as well as alternative battery options beyond lithium-ion. In 2021, we expect to see three key events unfold: • Increasing awareness of the impending shortage of li-ion materials • Zinc-ion batteries becoming increasingly viewed as lithium-ion’s successor • Emergence of new systems and business models to aggregate distributed energy storage.

Supply Chain Issues

Thanks to their high energy density, good service life, and strong power capability, lithium-ion has supplied more than 90 percent of large‐scale battery storage power capacity in the US (as of 2018). Continuing limitations with lithium-ion’s supply chain will challenge its continued growth. The raw materials used in lithium-ion batteries (including both lithium and cobalt) require substantial investment in new mining and processing facilities to keep pace with demand. China dominates the production of these materials, making the US and EU entirely dependent on trade with China to achieve their decarbonization goals. The COVID crisis revealed both the fragility of international supply chains, and the increasingly antagonistic relationship between Western governments and China. While lithium shortages are not expected until mid-decade, it is safe to predict that worries about this impending shortage will become a major focus of the battery industry in 2021. Expect continued government efforts on

JANUARY • FEBRUARY2021 /// www.nacleanenergy.com

developing domestic production of both batteries and their critical materials, including both mining and processing into finished chemicals. Also expect an increasing focus on non-lithium batteries from investment firms and government funding agencies.

Zinc-ion Batteries Emerging as a Lithium-ion Substitute

Lithium-ion batteries have always been a poor fit for stationary energy storage. Their defining feature - storing lots of energy in a small amount of weight - has little value for battery systems that never have to move. Paired with the high cost of lithium-ion and its intrinsic safety risks, the need for an alternative battery chemistry designed for renewable energy storage becomes clear. While many alternative chemistries have been recognized, (such as flow or zinc-air batteries) these are only useful for storage durations that are significantly longer than the typical 4 hours required by the market. They are also bulkier than lithium-ion, challenging their use in customersited systems. We need an alternative to lithium-ion that can store energy for 3-6 hours in a similar system size. The zinc-ion battery is just that – a safer, cheaper, and longer-lasting alternative to lithium-ion that offers similar power and energy density. Further, zinc-ion batteries use the same manufacturing processes as lithium-ion, while depending on raw materials that are abundant in North

America, making them a solution that can be rapidly scaled. While zinc-ion batteries have firmly established themselves as a nextgeneration technology in the research community, they are only now moving into commercialization. As zincion demonstrates its performance advantages in commercial prototypes, and proves its scalability at the pilot scale, we expect that its advantages in supply chain security, safety, and lifetime cost will become more widely accepted.

technologies like the zinc-ion battery will prove to be suitable contenders. The rise of new business models for energy storage, like the virtual power plant model, will impact the design of energy storage systems. While there certainly will be surprises and setbacks, energy storage has secured its role as a critical part of the energy transition. In 2021 and beyond, maturing business models and technologies will combine with a massively increasing scale to realize this potential.

Development of Systems and Business Models for Distributed Energy Storage

Energy storage systems can improve grid resiliency, delay infrastructure investment, reduce grid congestion, and more. Unfortunately, the market mechanisms required to enable all of these advantages have not been widely adopted. This is starting to change. Recent FERC orders require grid operators to allow distributed energy resources to compete in markets where they were previously barred, opening up new revenue streams for behind-the-meter energy storage. Additionally, more and more utilities are being proactive in engaging with projects that aggregate large amounts of distributed energy storage, allowing the utility to dispatch large amounts of power from many small systems. These projects are referred to as Virtual Power Plants (VPPs), and represent a revolution in how residential energy storage systems are deployed. This represents a major shift in the market. Traditionally, the economics of residential energy storage have not been great; purchases were primarily driven by the emotions of individual homeowners. With the emergence of aggregated systems, however, residential energy storage projects now offer far more appealing returns to attract financiers and project developers into the space. The rise of new aggregated business models will impact the design of energy storage systems. New features are needed in both the hardware and software to enable a utility to dispatch fleets of energy storage systems according to conditions in the grid. Safety concerns will become heightened, as project developers become responsible for thousands of systems operating in a home with conditions outside of their control. Therefore, expect the coming year to bring in a rise of safetyfocused systems with features tailored for aggregated, distributed energy storage.

A Look to the Future

Overall, 2021 should continue the trend of massive growth and impressive innovation in the energy storage industry. While concerns surrounding lithium-ionâ&#x20AC;&#x2122;s supply chain could become more prevalent, non-lithium North American Clean Energy

A Better Lithium Battery by Kevin Zanjani

In recent years, Lithium Iron Phosphate (LiFePO4) batteries have gained traction as a viable replacement for SLA/AGM batteries for energy storage applications. If that first sentence didn’t make much sense to you, don’t worry; you’ll be a little wiser by the time you read all the way to the end. You probably know them as the batteries that you use to power your snow blower, your electric car, or R/C vehicles. Technically, these batteries are known by their chemical makeup: LFP, Lithium Iron Phosphate, Lithium Ferrous Phosphate, LiFe, and LiFePO4. There’s a reason this battery technology is used so widely in so many applications - it has a tremendous degree of thermal and chemical stability. Just as importantly, this technology is also intrinsically safer because of an ultra-stable Fe-P-O chemical bond. If you’re a consumer trying to better understand the offerings out there – even if you’re a storage system provider who needs to explain the benefits of your system to a potential buyer – you run across terminology like charge cycles and lifespan. Essentially, these terms describe how much use you’ll get from the battery; every time you use up all the power in the battery and then recharge it until it’s ready to go again, it’s called a charge cycle. Due to the nature of chemicals, you don’t actually recharge the battery to a full 100 percent – each cycle “refills” the battery capacity

just short of the last full amount. How many times you’re able to complete this cycle is what defines the battery’s lifespan. The battery chemistry of a LiFePO4 appears to offer 3,000+ charge cycles, with manufacturers’ data showing at least 8 years in lifespan. In other words, based on average use (and what you’re using that battery for) it should last 8 years before you’ll need to replace it. Compared to other competing battery chemistries like Li-Ion Polymer (and chemistries based on LiCoO2, among others) LiFePO4 is considered to be robust in terms of cycle life and performance. Another kind of battery, SLA/AGM (used in cars and golf carts, etc.) pose dangers because they can sulfate, vent, or leak. Part of the inherent safety of LiFePO4 batteries is due to their non-toxic chemistry and tight chemical bond. LiFePO4 batteries are also a lot lighter -

High capacity single-unit charger

¼ the weight of SLA/AGM battery – and offer up to 10 times the charging cycles of their SLA/AGM cousins. Battery convenience is as important as battery life. That might sound strange, because batteries make life more convenient by their very nature. But many of the powerful batteries that most of use without a second thought actually need a little TLC (some more than others). Case in point, LiFePO4 batteries have a built-in advanced protection circuit module and battery management system. This prevents overcurrent, overdischarge, overvoltage, as well as internal balancing. In plain language, that means (respectively) better protection from overheating or fire, lowering battery life or fire, damaging equipment, as well as ruining the battery itself. On the other hand, SLA/AGM batteries have no internal circuitry, which means that it is possible to overdischarge this legacy battery chemistry – and that means it will need additional maintenance every 2 years (versus 8 to 12 years for LiFePo4). Additionally, due to the Peukert’s effect, SLA/AGM batteries have only a 50 percent usable capacity, after which point the voltage drops too low. LiFePO4 batteries boast a nearly 100 percent usable capacity. They also benefit from no memory effect, also known as “lazy battery”. If you continually recharge an SLA/AGM battery before it’s fully discharged, it starts to “forget” where its “fill line” is – it will keep recharging a little less each time until it dies. A LiFePO4 battery can be charged at 25, 50, or 75 percent state of charge. This makes it an excellent choice for both cyclic and standby applications like uninterruptible power systems (in case of power failures that require switching over to battery operation). Other benefits include a low self-discharge rate (about 2 – 3 percent per annum basis) and enhanced temperature performance (it lasts a long time in cold weather). For all you nascent battery aficionados, I hope this brief introduction to basic

battery chemistry was helpful. The main takeaway of all you’ve read here is that LiFePO4 batteries should be considered for various energy storage applications. It’s an attractive alternative to SLA/AGM batteries on the market, and should now be on your radar when researching the best battery for your needs.

Solar Battery or Generator? Keeping the lights on during power outages

by Daniel Mello Guimaraes

SEVERE WEATHER INCIDENTS ARE ON THE RISE.

From hurricanes and tornadoes, to severe thunderstorms and winter storms, New England homeowners are well-versed in the hours-long to days-long power outages that frequently accompany these storms. In light of this, more and more homeowners are investing in emergency power solutions. For many years, backup generators have been the choice of New England homeowners looking to power their essential appliances when the power goes out. But, significant growth in the number of solar power installs over recent years has changed that. For example, Massachusetts has 2,572 MW of (cumulative) capacity installed as of December 2019, surpassing its target of 1,600 MW of solar power installed for 2020, according to Mass.gov.1 With so many residents harnessing the power of the sun, another option has come front and center for when the power goes out - solar battery storage. With this increased interest in solar photovoltaic (PV) systems, utilizing solar battery storage as a back-up power option makes sense.

How each back-up system works

During a power outage, homeowners with grid-tied solar PV systems will be without power alongside those homeowners who are hooked up directly to the grid. But, those with a solar PV system combined with a solar battery will be able to power their home without interruption. As the PV system disconnects during an outage, the solar battery kicks in. Backup generators burn fossil fuels (propane, natural gas, or diesel) to create their own electricity. They may have sensors to detect an outage, which provides automatic operation, kicking in when the power goes out.

Solar battery benefits

Solar battery systems store excess energy - from a power source such as a solar PV system or the electricity grid - for later use. Solar battery back-up may be used during an outage or during times of high electricity rates. There are a number of benefits to utilizing a solar battery. Among its most important features are quiet operation and low maintenance. When combined with a solar PV system, it operates on renewable energy, which enables customers to optimize their daily solar consumption (while minimizing consumption from the grid). While there is a higher upfront cost when compared to a generator, but the good news is that a solar battery is eligible for federal tax credit incentives and the homeowner will save on maintenance. The size of a solar battery backup system or generator will dictate the household equipment that can be powered during an outage. The latest solar battery has 13.5 kWh of storage capacity, which the homeowner can stack (two or three) to get even more storage. Depending on size, a solar battery backup system can power essential energy loads such as keeping the lights and refrigerator on, or it can power the whole home.

Benefits of a Generator

There are a number of advantages to utilizing a backup generator. Perhaps the most significant is cost: Generators are typically less expensive upfront than solar batteries. They can also be connected to a natural gas line. As long as they are given a steady

JANUARY â&#x20AC;˘ FEBRUARY2021 /// www.nacleanenergy.com

system, it provides seamless operation during an outage. Not only does it reduce reliance on fossil fuels, it increases selfconsumption of solar power generation. Plus, the homeowner is able to take advantage of the federal tax credit. Many homeowners have questions about the overall cost of installation, the availability of tax credit incentives, and annual electric savings. It’s best to address these topics during a consultation with a solar provider, during which they can get a comprehensive review. In this way, a homeowner will be able to make an informed decision, and feel more confident about powering their home during outages.

Boston Solar markets, designs, and installs residential and commercial solar, as well as energy storage and EV chargers throughout Massachusetts. fuel supply, generators can provide power 24/7. Options range from a small portable generator to a whole-home standby. Drawbacks include noisy operation and required maintenance, as well as monthly fuel costs (along with location pollution and a higher carbon footprint).

How to Decide

So, what’s the best option? It really depends on a number of aspects, whether usage and cost or a homeowner’s overall inclination to reduce their carbon footprint by utilizing solar energy. Homeowners who are only looking for emergency power, are in a home with an existing natural gas line or can hook up to propane, and who are not planning to install solar panels on their roof in the future, may prefer the option of a standby backup generator. There are some homes where solar PV installation is not conducive, due to one or more structural features. For example, in New England, most homes have asphalt shingles that work well with a solar system. But some have tile, which are not favorable to solar PV. If a home is not a good fit for a solar PV install, a solar battery is still an option, but better option may be a generator. For those who would like to (quietly) power their home 24/7 - and during outages with renewable energy - solar battery power with a solar PV system is the best option. A solar battery can actually run without solar PV installed, because it can be charged. However, recommended usage is solar PV plus solar battery storage. When a solar battery is combined with a solar PV

Integrated whole-home solar power solution

Generac Power Systems’ PWRcell end-toend solar and storage system is capable of providing intelligently managed backup power to the entire home. The new PWRcell Automatic Transfer Switch, (PWRcell ATS), includes integrated load management, high-capacity batteries rated up to 18kWh, and an outdoor-rated enclosure that allows for a simple, flexible, and 100% outdoor installation. PWRcell ATS allows Generac’s system to power the entire electrical panel. In the event of a power outage, the PWRcell ATS disconnects from the grid, allowing the whole home to be islanded as power is routed from the battery and solar array to the home’s electrical panel. Because Generac protects the entire home, the need to move or transfer circuits to a separate sub-panel is eliminated, reducing system complexity and installation time. To further bolster the whole-home capabilities of the PWRcell system, Generac has unlocked additional power output and is introducing a combination of load management options. With improved performance, the PWRcell inverter can now deliver 9kW of backup power from a single battery pack and up to 11kW from a dual battery system. Generac Smart Management Modules work with the load management device built into the ATS to manage all of that power and protect against system overload. When paired together, the PWRcell ATS and SMMs allow up to 12 circuits to be managed and prioritized. By controlling how power is allocated, the PWRcell system not only keeps all the essentials running, but it provides the opportunity to start larger home appliances like air conditioners and water heaters during a utility power outage.

QuickBOLT: The Original Top Mount 8 years ago our competitors said top mount installation methods would never work, installers will never go for it, and you can’t get around lifting shingles. Well that wasn’t good enough. We took the leap anyways, because we believed not lifting shingles was the answer to installer’s problems. We believed solar mounting could be easier.

Each year that goes by makes QuickBOLT the longest standing top mount solution on the market, and with zero reported leaks. But don’t just take it from us, hear it from YOUR competitors in our customer testimonials. They’ll prove to you why you should try out the QuickBOLT on your next project.

We heard how traditional flashing was falling short, and we acted. For 8 years since then, installers have been adopting QuickBOLT’s compression-sealing method and for 8 years we’ve continually proven this method to be tried and true for speed and effect. Our recommendation of installing over the shingle has steadily become the fastest growing solution amongst our customers AND our competitors - and we couldn’t be more excited!

Scan this QR code to watch video.

There may be other top mount solutions on the market but none of them have been on roofs as long as the QuickBOLT. Plus, QuickBOLT is the ONLY compression-sealed top mount solution. Why get the knock-offs when you can have the original?

8 Years Ahead of the Curve... Black & McDonald Black & McDonald is an integrated, multi-trade service provider that safely delivers high-quality construction, facilities management, and technical solutions to government, institutional, and industry clients.

A radiant heating technology based on a self-regulating Nano poly carbon material, which operates on low-voltage AC or DC. Due to its unique self-regulating properties, the heating element cannot overheat as the nature of the polymer material automatically reduces or increases its heat output to adjust to the temperature changes. This means that when the ambient temperature increases, the electrical resistance increases, and the consumption of electricity decreases. These heating elements can be used to warm floors in homes and buildings, de-ice and melt snow on roofs and ramps, and also keep solar panels free from snow.

Buildings vs. Behavior Why structural energy efficiency is the future of energy conservation by Nishaant Sangaavi

Which takes more effort, altering a people’s conservation habits or altering the buildings they occupy? Considering how long the average New Year’s resolution lasts, it’s safe to assume that installing the latest energy-saving application may be a lot easier. In fact, we have the data to back this up.

Building retrofits can unlock energy savings of 60 percent1, giving them the power to fundamentally impact the way we consume energy. However, deep energy retrofits often require structural upgrades, which are often complicated to understand and expensive to implement. As a result, people tend to shy away from these bold actions, preferring to opt for low- or no-touch behavioral recommendations. These small, incremental improvements only produce energy savings of between two to seven percent; they also require us to focus on changing the way we live in our homes. The smarter alternative is having our homes operate better, become healthier environments, and give us the power to go well beyond single-digit energy savings. It’s imperative that we take bolder action in improving our building stock so we can meet our collective energy efficiency and climate change goals through deep energy retrofits. While structural energy efficiency upgrades are more expensive to implement, they last for the life of the building and continue to provide energy savings regardless of a change in occupants or their behavior. Behavioral programs, in contrast, require the active participation of homeowners in maintaining appliances and monitoring equipment, and can be rendered ineffective if customers become less engaged over time. The result? Behavioral upgrades such as smart meters and thermostats often lack longevity. For example, in a study on smart meter adoption2, researchers found that households who implemented smart meters produced non-significant energy savings: -0.04KWh to -0.15KWh per month. To

make real progress in reducing energy consumption, utilities and other administrators must shift gears and focus on innovative ways (PACE, financing, labelling) to support consumers participation in structural energy efficiency upgrades. These upgrades stand the test of time. They last as long as the building stock, and deliver consistent, substantial energy savings regardless of who lives in the building. One major barrier in the delivery of retrofits and structural energy efficiency upgrades has been scalability. Often, the programs that support deep retrofit upgrades require on-site visits from certified auditors, who must be compensated for their time and expertise. On-site auditors also rely on coordinating and managing multiple contractors and vendors, and measuring and verifying several types of results. This data collection process can be laborious and costly, and doesn’t even include the scheduling or costs required for the project work based on the eventual retrofit itself. From the audit alone, the desks of program managers and customer service representatives pile up with applications and administrative paperwork required to manage multiple quotes, invoices, and vendor and customer inquiries. All of this can cause delays, negatively impacting the customer experience and ultimately, deterring participation. Utilities and other Program Administrators may offer rebates and other incentives to offset the costs of structural energy efficiency recommendations, which sometimes works. But not often enough. Fortunately, this can be a problem of the past. Two main barriers prevent uptake of structural

Energy management ecosystem

energy efficiency: clear cost-benefit analyses for customers, and the overall price tag for the consumer and utility provider. Technology -- particularly machine learning and AI -eliminates these problems. We no longer have to struggle with accurately conveying the return on investment of structural efficiency, or the cost-burden borne by utilities to administer the programs. The innovative data science we’ve become accustomed to utilizing in almost every other sector can also be leveraged by utilities to deliver modern day programs, and make deep energy retrofits more accessible and compelling. Today, technology is revolutionizing the ability to identify deep retrofit opportunities, and to work hand-in-hand with auditors, vendors, and stakeholders to deliver those opportunities at scale. Using a data-driven approach, customers with the most need for deep retrofits can be identified and triaged accordingly. Policy makers are also beginning to understand this: In his campaign, President Elect Biden called for a $2-trillion, four-year investment in climate-related projects3, including the ambitious target of retrofitting

four million buildings. Through technology we can increase retrofit timelines, improve the customer experience, and maximize energy efficiency program dollars. This will ensure that we meet our ambitious North American netzero and climate change commitments.

Calculate the value of energy flexibility

GridBeyond has released a free online tool for use within the commercial and industrial industry, the Energy Opportunity Calculator. The tool enables industrial and commercial businesses to calculate how much money they could earn and save through demand response and energy optimization services. Energy users quickly and simply enter three pieces of information: location, industry, and electricity consumption, and the calculator outputs the estimated financial benefits they could achieve. The results are split into two sections, revenues and savings. The tool uses the typical percentage of flexibility for the user’s industry, the typical services and programs available to that industry, and the values of those programs to generate the results. The revenues are based on demand response and other network opportunities, while the savings are based upon typical energy efficiencies, trading, and price optimization opportunities, as well as the operational efficiencies that can be attained. The user can then download a custom-made, personalized report containing further detail on their results, with additional information on the services they can participate in, the assets typically found in their industry, and an overview of their market.
