Major Breakthrough Unveiled: Transformative Advances in Sustainable EV Battery Repurposing
May 08, 2024
Major Breakthrough Unveiled: Transformative Advances in Sustainable EV Battery Repurposing

The global transition towards sustainable energy sources is accelerating, driven by the urgent need to mitigate climate change and reduce reliance on fossil fuels. Central to this transition is the widespread adoption of renewable energy technologies such as wind and solar power. However, the intermittent nature of renewable energy sources presents a challenge for grid stability and reliability. Energy storage solutions, particularly battery energy storage systems (BESS), play a crucial role in addressing these challenges by storing excess energy during periods of low demand and releasing it when needed.

In recent years, there has been a significant increase in the deployment of battery energy storage systems worldwide. According to Bloomberg New Energy Finance (BNEF), the global battery energy storage market is expected to grow exponentially, reaching 1877GWh by 2030, with an annual addition of 443GWh, reflecting a remarkable 21% compound annual growth rate (CAGR). This rapid growth underscores the importance of energy storage in transitioning to a low-carbon economy.

However, despite the increasing adoption of battery energy storage systems, there are challenges associated with the lifespan of batteries. Traditional lithium-ion batteries, commonly used in energy storage applications, degrade over time, leading to reduced performance and capacity. LG estimates that batteries typically retain only 60% of their capacity after 10 years of use, making them unsuitable for continued operation.

Addressing the Challenge of Battery Lifespan

To address the challenge of battery lifespan, researchers and industry stakeholders have been exploring innovative solutions to extend the longevity of batteries and maximize their value. A study published in Cell Reports Physical Science, a flagship journal of Cell Press, by Relyion Energy Inc. and Stanford University demonstrated that retired EV batteries, which have been used for up to a decade in their primary first life, could be repurposed for second life applications for an up to almost two decades. This is remarkably 3-4X life vs. any other state of the art technology.

This groundbreaking research has significant implications for the energy storage industry, as it opens up new possibilities for extending the battery lifespan. Relyion Energy Inc. will accelerate large-scale adoption of new battery energy storage systems with its proprietary adaptive battery management systems technology that can work with new and second-life batteries to make them last for 20 to 30 years.

While the use of second life for retired batteries for 20 years is a significant advancement in increasing the sustainability and, ultimately, circularity of Lithium-ion batteries, the lifetime extension is also important for new battery energy storage systems. Typically, the BESS is tied to renewable energy assets such as wind and solar where the projects are 30+ years of life while the BESS is limited to 10 years. This requires dismantling, removal, and new installation in addition to augmentation etc. This leads to a double whammy situation where a costly asset is used for a short duration and adds significant additional cost because of removal and re-installation.

Unlike traditional BMS, which are often limited by battery chemistry and source, the new technology is adaptable to a wide range of battery types and conditions. This flexibility allows the authors to work with both new and second-life batteries, optimizing their performance in real-time to maximize longevity.

Dr. Surinder Singh, CEO of Relyion Energy, stated that the cutting-edge technology on battery management system is capable of increasing the BESS life to match with other renewable assets while being independent of the battery chemistry, type, source, degradation, internal resistance, or state of health.

Prof Simona Onori, from Stanford University and co-author of the article, said, "The need for a robust Battery Management System (BMS) for second-life batteries is paramount. Our work, rooted in hands-on experimentation with retired EV batteries, has resulted in the creation of BMS2, which is tailored to optimize the performance of repurposed batteries, ensuring their reliability in sustainable energy setups. Our efforts contribute to a greener future by extending the lifespan of these batteries and facilitating their seamless integration into energy systems.

Overall, the technology represents a significant advancement in battery management technology, enabling the seamless integration of new and second-life batteries into energy storage systems. By maximizing the lifespan of batteries and optimizing their performance, Relyion is helping to drive the widespread adoption of energy storage solutions and accelerate the transition to a sustainable energy future.

Energy storage plays a crucial role in the shift towards sustainable energy, and Relyion is unwavering in its mission to provide top-tier and long-lasting energy storage solutions worldwide. The introduction of the BMS marks another significant step in the authors' dedication to this transition. Moving forward, Relyion will continue its steadfast commitment to open innovation, working alongside global industry partners to lead the way in innovation and cutting-edge technology for mutual success.

Sinovoltaics Releases Q2 Financial Ranking Reports for Solar, Storage, and Inverter Companies

Sinovoltaics, a leader in quality assurance, ESG, and traceability for the solar photovoltaic and battery energy storage system industries, announced the release of its second quarterly financial ranking reports for 2024. The reports evaluate the financial stability of publicly listed manufacturers of PV modules, energy storage, and inverters across the U.S., Europe, and Asia. 

Since 2016, Sinovoltaics has collected publicly available financial data to rank companies using the Altman Z-Score, a widely recognized financial assessment tool. This tool measures a company’s financial health through profitability, leverage, liquidity, solvency, and activity ratios. Scores at or below 1.1 suggest a higher risk of bankruptcy within two years, while scores above 2.6 indicate strong financial health. The full reports for solar modules, energy storage, and inverters are available as free downloads on the Sinovoltaics website. 

“Due to overcapacity along the solar supply chain, many Tier 1 manufacturers are operating at a loss, resulting in a decline in the Altman Z-scores across several factories,” said Dricus de Rooij, co-founder and CEO of Sinovoltaics. "While quarterly fluctuations are normal, our data from June 2021 to March 2024 offers long-term insights into the financial trends of manufacturers, aiding developers in sourcing and comparing the financial stability of manufacturers.” 

Unlike the Bloomberg PV Module Tier 1 List, which factors in criteria like bankability and production capacity, Sinovoltaics focuses solely on financial health based on the Altman Z-Score. This approach provides a transparent, apples-to-apples comparison of financial stability, benefiting reporters, developers, and manufacturers alike.  

Solar developers, procurement managers, and financiers can use these rankings to evaluate and compare publicly traded manufacturers’ financial stability and evaluate the strength of enforceable warranties. In addition, with increasing price competition for Asian suppliers and new manufacturing facilities being built in the U.S. due to the Inflation Reduction Act (IRA), Sinovoltaics also recommends solar and energy storage developers conduct thorough factory audits and quality inspections to mitigate investment risks and technical failures.

Investing in the Future: Mobilizing capital and partnerships for a sustainable energy transition

Unleashing trillions of dollars for a resilient energy future is within our grasp — if we can successfully navigate investment risk and project uncertainties.

The money is there — so where are the projects?

A cleaner and more secure energy future will depend on tapping trillions of dollars of capital. The need to mobilize money and markets to enable the energy transition was one of the key findings of one of the largest studies ever conducted among the global energy sector C-suite. This will mean finding ways to reduce the barriers and uncertainties that prevent money from flowing into the projects and technologies that will transform the energy system. It will also mean fostering greater collaboration and alignment among key players in the energy space.

stocksInterestingly, the study found that insufficient access to finance was not considered the primary cause of the current global energy crisis. In fact, capital was seen to be available — but not being unlocked. Why is that? The answer lies in the differing risk profiles of energy transition investments around the world. These risks manifest in multiple ways, including uncertainties relating to project planning, public education, stakeholder engagement, permitting, approvals, policy at national and local levels, funding and incentives, technology availability, and supply chains.

These risks need to be addressed to create more appealing investment opportunities for both public and private sector funders. This will require smart policy and regulatory frameworks that drive returns from long-term investment into energy infrastructure. It will also require investors to recognize that resilient energy infrastructure is more than an ESG play — it is a smart investment in the context of doing business in the 21st century.

Make de-risking investment profiles a number one priority

According to the study, 80 percent of respondents believe the lack of capital being deployed to accelerate the transition is the primary barrier to building the infrastructure required to improve energy security. At the same time, investors are looking for opportunities to invest in infrastructure that meets ESG and sustainability criteria. This suggests an imbalance between the supply and demand of capital for energy transition projects.

How can we close the gap?

One way is to link investors directly to energy companies. Not only would this enable true collaboration and non-traditional partnerships, but it would change the way project financing is conceived and structured — ultimately aiding in potentially satisfying the risk appetite of latent but hugely influential investors, such as pension funds. The current mismatch of investor appetite and investable projects reveals a need for improving risk profiles, as well as a mindset shift towards how we bring investment and developer stakeholders together for mutual benefit. The circular dilemma remains: one sector is looking for capital to undertake projects within their skill to deploy, while another sector wonders where the investable projects are.

This conflict is being played out around the world; promising project announcements are made, only to be followed by slow progress (or no action at all). This inertia results when risks are compounded and poorly understood. To encourage collaboration between project developers and investors with an ESG focus, more attractive investment opportunities can be created by pulling several levers: public and private investment strategies, green bonds and other sustainable finance instruments, and innovative financing models such as impact investing.

Expedite permitting to speed the adoption of new technologies

Another effective strategy to de-risk investment profiles is found in leveraging new technologies and approaches that reduce costs, increase efficiency, and enhance the reliability of energy supply. Research shows that 62 percent of respondents indicated a moderate or significant increase in investment in new and transitional technologies respectively, highlighting the growing interest in innovative solutions to drive the energy transition forward.

Hydrogen, carbon capture and storage, large-scale energy storage, and smart grids are some of the emerging technologies identified by survey respondents as having the greatest potential to transform the energy system and create new investment opportunities. However, these technologies face challenges such as long lag times between conception and implementation. 

If the regulatory environment makes sense, then policy uncertainty is reduced, and the all-important permitting pathways are well understood and can be navigated. Currently, the lack of clear, timely, and fit-for-purpose permitting is a major roadblock to the energy transition. To truly unleash the potential of transitional technologies requires the acceleration of regulatory systems that better respond to the nuance and complexity of such technologies (rather than the current one-size-fits all approach). In addition, permitting processes must also be expedited to dramatically decrease the period between innovation, commercialization, and implementation. One of the key elements of faster permitting is effective consultation with stakeholders and engagement with communities where these projects will be housed for decades. This is a highly complex area that requires both technical and communication skills.

The power of collaboration, consistency, and systems thinking

The report also reveals the need for greater collaboration among companies in the energy space to build a more resilient system. The report shows that, in achieving net zero, there is a near-equal split between those increasing investment (47 percent of respondents), and those decreasing investment (39 percent of respondents). This illustrates the complexity and diversity of the system around the world. A more resilient system will require all its components – goals and actions – to be aligned towards a common outcome.

Another way to de-risk the energy transition is to establish consistent, transparent, and supportive policy frameworks that encourage investment and drive technological innovation. The energy transition depends on policy to guide its direction and speed by affecting how investors feel and how the markets behave. However, inconsistent or inadequate policy can also be a source of uncertainty and instability. For example, shifting political priorities, conflicting international standards, and the lack of market-based mechanisms can hinder the deployment of sustainable technologies, resulting in a reluctance to commit resources to long-term projects.

electric little car

Variations in country-to-country deployment creates disparities in energy transition progress. For instance, the 2022 Inflation Reduction Act in the US has posed challenges for the rest of the world, by potentially channeling energy transition investment away from other markets and into the US. This highlights the need for a globally unified approach to energy policy that balances various national interests while addressing a global problem.

To facilitate the energy transition, it is imperative to establish stable, cohesive, and forward-looking policies that align with global goals and standards. By harmonizing international standards, and providing clear and consistent signals, governments and policymakers can generate investor confidence, helping to foster a robust energy ecosystem that propels the sector forward.

Furthermore, substantive and far-reaching discussions at international events like the United Nations Conference of the Parties (COP), are essential to facilitate this global alignment. These events provide an opportunity to de-risk the energy transition through consistent policy that enables countries to work together, ensuring that the global community can tackle the challenges and opportunities of the energy transition as a united front.

Keeping net-zero ambitions on track

Despite the challenges faced by the energy sector, the latest research reveals a key positive: 91 percent of energy leaders surveyed are working towards achieving net zero. This demonstrates a strong commitment to the transition and clear recognition of its importance. It also emphasizes the need to accelerate our efforts, streamline processes, and reduce barriers to realizing net-zero ambitions — and further underscores the need to de-risk energy transition investment by removing uncertainties.

The solution is collaborating and harmonizing our goals with the main players in the energy sector across the private and public sectors, while establishing consistent, transparent, and supportive policy frameworks that encourage investment and drive technological innovation.

These tasks, while daunting, are achievable. They require vision, leadership, and action from all stakeholders involved. By adopting a new mindset about how we participate in the energy system and what our obligations are, we can stimulate the rapid progress needed on the road to net zero.

Lessons Learned: The first case of heavy maintenance on floating wind

Lessons Learned: The first case of heavy maintenance on floating wind

The Kincardine floating wind farm, located off the east coast of Scotland, was a landmark development: the first commercial-scale project of its kind in the UK sector. Therefore, it has been closely watched by the industry throughout its installation. With two of the turbines now having gone through heavy maintenance, it has also provided valuable lessons into the O&M processes of floating wind projects. 

In late May, the second floating wind turbine from the five-turbine development arrived in the port of Massvlakte, Rotterdam, for maintenance. An Anchor Handling Tug Supply (AHTS)

vessel was used to deliver the KIN-02 turbine two weeks after a Platform Supply Vessel (PSV) and AHTS had worked to disconnect the turbine from the wind farm site. The towing vessel became the third vessel used in the operation.

This is not the first turbine disconnected from the site and towed for maintenance. In the summer of 2022, KIN-03 became the world’s first-ever floating wind turbine that required heavy maintenance (i.e. being disconnected and towed for repair). It was also towed from Scotland to Massvlakte. 

Each of these operations has provided valuable lessons for the ever-watchful industry in how to navigate the complexities of heavy maintenance in floating wind as the market segment grows.

The heavy maintenance process

When one of Kincardine’s five floating 9.5 MW turbines (KIN-03) suffered a technical failure in May 2022, a major technical component needed to be replaced. The heavy maintenance strategy selected by the developer and the offshore contractors consisted in disconnecting and towing the turbine and its floater to Rotterdam for maintenance, followed by a return tow and re-connection. All of the infrastructure, such as crane and tower access, remained at the quay following the construction phase. (Note, the following analysis only covers KIN-03, as details of the second turbine operation are not yet available). 

Comparing the net vessel days for both the maintenance and the installation campaigns at this project highlights how using a dedicated marine spread can positively impact operations. 

For this first-ever operation, a total of 17.2 net vessel days were required during turbine reconnection—only a slight increase on the 14.6 net vessel days that were required for the first hook-up operation performed during the initial installation in 2021. However, it exceeds the average of eight net vessel days during installation. The marine spread used in the heavy maintenance operation differed from that used during installation. Due to this, it did not benefit from the learning curve and experience gained throughout the initial installation, which ultimately led to the lower average vessel days.

The array cable re-connection operation encountered a similar effect. The process was performed by one AHTS that spent 10 net vessel days on the operation. This compares to the installation campaign, where the array cable second-end pull-in lasted a maximum of 23.7 hours using a cable layer.

Overall, the turbine shutdown duration can be broken up as 14 days at the quay for maintenance, 52 days from turbine disconnection to turbine reconnection, and 94 days from disconnection to the end of post-reconnection activities.

What developers should keep in mind for heavy maintenance operations

This analysis has uncovered two main lessons developers should consider when planning a floating wind project: the need to identify an appropriate O&M port, and to guarantee that a secure fleet is available. ‍

  • Identification of the O&M port

Floating wind O&M operations require a port with both sufficient room and a deep-water quay. The port must also be equipped with a heavy crane with sufficient tip height to accommodate large floaters and reach turbine elevation. Distance to the wind farm should also be taken into account, as shorter distances will reduce towing time and, therefore, minimize transit and non-productive turbine time. 

During the heavy maintenance period for KIN-03 and KIN-02, the selected quay (which had also been utilized in the initial installation phase of the wind farm project), was already busy as a marshalling area for other North Sea projects. This complicated the schedule significantly, as the availability of the quay and its facilities had to be navigated alongside these other projects. This highlights the importance of abundant quay availability both for installation (long-term planning) and maintenance that may be needed on short notice. ‍

  • A secure fleet

At the time of the first turbine’s maintenance program (June 2022), the North Sea AHTS market was in an exceptional situation: the largest bollard pull AHTS units contracted at over $200,000 a day, the highest rate in over a decade. 

During this time, the spot market was close to selling out due to medium-term commitments, alongside the demand for high bollard pull vessels for the installation phase at a Norwegian floating wind farm project. The Norwegian project required the use of four AHTS above a 200t bollard pull. With spot rates ranging from $63,000 to $210,000 for the vessels contracted for Kincardine’s maintenance, the total cost of the marine spread used in the first repair campaign was more than $4 million.

Developers should therefore consider the need to structure maintenance contracts with AHTS companies, either through frame agreements or long-term charters, to decrease their exposure to spot market day rates as the market tightens in the future.

While these lessons are relevant for floating wind developers now, new players are looking towards alternative heavy O&M maintenance options for the future. Two crane concepts are especially relevant in this instance. The first method is for a crane to be included in the turbine nacelle to be able to directly lift the component which requires repair from the floater, as is currently seen on onshore turbines. This method is already employed in onshore turbines and could be applicable for offshore. The second method is self-elevating cranes with several such solutions already in development.

The heavy maintenance operations conducted on floating turbines at the Kincardine wind farm have provided invaluable insights for industry players, especially developers. The complex process of disconnecting and towing turbines for repairs highlights the need for meticulous planning and exploration of alternative maintenance strategies, some of which are already in the pipeline. As the industry evolves, careful consideration of ports, and securing fleet contracts, will be crucial in driving efficient and cost-effective O&M practices for the floating wind market.

Choosing the Right Partner Mitigates Project Risk

According to the Energy Information Administration (EIA), developers plan to add 54.5 gigawatts (GW) of new utility-scale electric generating capacity to the U.S. power grid in 2023. More than half of this capacity will be solar. Wind power and battery storage are expected to account for roughly 11 percent and 17 percent, respectively.

A large percentage of new installations are being developed in areas that are prone to extreme weather events and natural disasters (e.g., Texas and California), including high wind, tornadoes, hail, flooding, earthquakes, wildfires, etc. With the frequency and severity of many of these events increasing, project developers, asset owners, and tax equity partners are under growing pressure to better understand and mitigate risk.

In terms of loss prevention, a Catastrophe (CAT) Modeling Study is the first step to understanding the exposure and potential financial loss from natural hazards or extreme weather events. CAT studies form the foundation for wider risk management strategies, and have significant implications for insurance costs and coverage. 

Despite their importance, developers often view these studies as little more than a formality required for project financing. As a result, they are often conducted late in the development cycle, typically after a site has been selected. However, a strong case can be made for engaging early with an independent third party to perform a more rigorous site-specific technical assessment. Doing so can provide several advantages over traditional assessments conducted by insurance brokerage affiliates, who may not possess the specialty expertise or technical understanding needed to properly apply models or interpret the results they generate. One notable advantage of early-stage catastrophe studies is to help ensure that the range of insurance costs, which can vary from year to year with market forces, are adequately incorporated into the project financial projections. 

The evolving threat of natural disasters

Over the past decade, the financial impact of natural hazard events globally has been almost three trillion dollars. In the U.S. alone, the 10-year average annual cost of natural disaster events exceeding $1 billion increased more than fourfold between the 1980s ($18.4 billion) and the 2010s ($84.5 billion).

Investors, insurers, and financiers of renewable projects have taken notice of this trend, and are subsequently adapting their behavior and standards accordingly. In the solar market, for example, insurance premiums increased roughly four-fold from 2019 to 2021. The impetus for this increase can largely be traced back to a severe storm in Texas in 2019, which resulted in an $80 million loss on 13,000 solar panels that were damaged by hail.  

The event awakened the industry to the hazards severe storms present, particularly when it comes to large-scale solar arrays. Since then, the impact of convective weather on existing and planned installations has been more thoroughly evaluated during the underwriting process. However, far less attention has been given to the potential for other natural disasters; events like floods and earthquakes have not yet resulted in large losses and/or claims on renewable projects (including wind farms). The extraordinary and widespread effect of the recent Canadian wildfires may alter this behavior moving forward.

A thorough assessment, starting with a CAT study, is key to quantifying the probability of their occurrence — and estimating potential losses — so that appropriate measures can be taken to mitigate risk. 

All models are not created equal

Industrywide, certain misconceptions persist around the use of CAT models to estimate losses from an extreme weather event or natural disaster. 

submerged cars

Often, the perception is that risk assessors only need a handful of model inputs to arrive at an accurate figure, with the geographic location being the most important variable. While it’s true that many practitioners running models will pre-specify certain project characteristics regardless of the asset’s design (for example, the use of steel moment frames without trackers for all solar arrays in a given region or state), failure to account for even minor details can lead to loss estimates that are off by multiple orders of magnitude. 

The evaluation process has recently become even more complex with the addition of battery energy storage. Relative to standalone solar and wind farms, very little real-world experience and data on the impact of extreme weather events has been accrued on these large-scale storage installations. Such projects require an even greater level of granularity to help ensure that all risks are identified and addressed. 

Even when the most advanced modeling software tools are used (which allow for thousands of lines of inputs), there is still a great deal that is subject to interpretation. If the practitioner does not possess the expertise or technical ability needed to understand the model, the margin for error can increase substantially. Ultimately, this can lead to overpaying for insurance. Worse, you may end up with a policy with insufficient coverage. In both cases, the profitability of the asset is impacted. 

Supplementing CAT studies

In certain instances, it may be necessary to supplement CAT models with an even more detailed analysis of the individual property, equipment, policies, and procedures. In this way, an unbundled risk assessment can be developed that is tailored to the project. Supplemental information (site-specific wind speed studies and hydrological studies, structural assessment, flood maps, etc.) can be considered to adjust vulnerability models.

This provides an added layer of assurance that goes beyond the pre-defined asset descriptions in the software used by traditional studies or assessments. By leveraging expert elicitations, onsite investigations, and rigorous engineering-based methods, it is possible to discretely evaluate asset-specific components as part of the typical financial loss estimate study: this includes Normal Expected Loss (NEL), also known as Scenario Expected Loss (SEL); Probable Maximum Loss (PML), also known as Scenario Upper Loss (SUL); and Probabilistic Loss (PL). 

Understanding the specific vulnerabilities and consequences can afford project stakeholders unique insights into quantifying and prioritizing risks, as well as identifying proper mitigation recommendations. 

Every project is unique

The increasing frequency and severity of natural disasters and extreme weather events globally is placing an added burden on the renewable industry, especially when it comes to project risk assessment and mitigation. Insurers have signaled that insurance may no longer be the main basis for transferring risk; traditional risk management, as well as site and technology selection, must be considered by developers, purchasers, and financiers. 

As one of the first steps in understanding exposure and the potential capital loss from a given event, CAT studies are becoming an increasingly important piece of the risk management puzzle. Developers should treat them as such by engaging early in the project lifecycle with an independent third-party practitioner with the specialty knowledge, tools, and expertise to properly interpret models and quantify risk. 

Hazards and potential losses can vary significantly depending on the project design and the specific location. Every asset should be evaluated rigorously and thoroughly to minimize the margin for error, and maximize profitability over its life.
