The Electric Power Research Institute’s (EPRI) Energy Storage Integration Council (ESIC) held a Strategy Meeting on September 14, 2023 at the JW Marriott in Indianapolis to focus on identifying the energy storage gaps and how ESIC can address them.
The mission of ESIC is to advance the deployment and integration of energy storage systems through open, technical collaboration.
This meeting was open to the technical community of energy storage stakeholders, such as electric utilities, energy storage developers and integrators, regulators, system operators, independent power producers, and research and consulting organizations.
As the technical voice of the lead battery industry, CBI sent US Research and Innovation Manager, Dr. Alyssa McQuilling, to share and collaborate on industry insights.
Her takeaways from the event included:
Lastly, the six national labs have to a role to play in getting emerging technologies ‘over the hump’ in terms of development. This includes those opportunities created through Grid Storage Launchpad and ROVI (Rapid Operational Validation Initiative).
We look forward to seeing CBI’s members transform projects into products that can benefit industry and utilities in meeting their renewable integration and decarbonization goals.
The European Energy Transition
By Nicola Filizola
As the world copes with the urgent need to address climate change and reduce greenhouse gas emissions, Europe has been leading the charge in transitioning to a cleaner and more sustainable energy future. The European energy transition is a comprehensive shift from traditional fossil fuels to renewable energy sources, such as wind, solar, hydro, and geothermal power. Among the critical components enabling this transformation, lead batteries have emerged as a key technology that plays a pivotal role in the transition's success. In this article, we will explore the energy transition in Europe and delve into the essential role that batteries are playing in shaping the continent's greener and brighter future.
The Growth of Renewable Energy in Europe
The European Union (EU) has been at the forefront of advocating for clean energy and sustainability. Through initiatives like the European Green Deal and the Paris Agreement, EU member states are committed to reducing their carbon emissions, fostering innovation in clean technologies, and achieving climate neutrality by 2050.
One of the main challenges of integrating renewable energy sources into the existing energy infrastructure is their intermittency. Solar and wind power, for instance, depend on weather conditions and daylight availability. To ensure a stable and reliable energy supply, an efficient energy storage system is essential, and that's where batteries come into the picture.
The Challenge of Intermittency
Unlike conventional power plants that can provide a consistent energy output, solar and wind power are dependent on weather conditions and natural variations. Cloudy days and calm winds can lead to a drop in power generation, causing fluctuations in the grid. This intermittency poses challenges to grid stability, and the power supply must be balanced in real-time to meet demand. If renewable energy sources are to dominate the energy mix, an effective and efficient energy storage solution is imperative to address this variability.
Batteries: The Key to Storing Renewable Energy
Batteries are essential components of the energy transition as they serve as a bridge between renewable energy generation and consumption. These energy storage systems can store surplus electricity when generation exceeds demand and release it when demand surpasses generation. In essence, batteries help to smooth out the intermittent nature of renewables and provide a stable supply of electricity to the grid.
Batteries act as buffers, absorbing excess energy during periods of high generation and releasing it when generation dips. By doing so, they stabilize the grid and ensure a steady supply of electricity, reducing the risk of blackouts and power disturbances. Moreover, batteries can respond rapidly to fluctuations in demand, providing grid operators with a valuable tool to manage the grid effectively.
The energy transition in Europe is also characterized by a shift towards decentralization, with an increasing number of small-scale renewable energy installations, such as rooftop solar panels and community wind farms. Batteries play a vital role in this decentralized energy landscape by enabling consumers to store and manage their locally generated energy. This promotes energy autonomy, reducing the reliance on centralized power plants and enhancing energy security.
Batteries make it possible to integrate a higher share of renewables into the grid. By storing excess energy during periods of high generation, batteries ensure that the energy is not wasted and can be used during times of low generation. This feature is particularly crucial during seasonal variations when renewable output may vary significantly.
Batteries also play a significant role in electrifying transportation, another essential aspect of the energy transition. The growth of electric vehicles (EVs) is dependent on advanced battery technology, allowing for longer driving ranges and faster charging times. Widespread EV adoption not only reduces greenhouse gas emissions from the transportation sector but also opens up the possibility of using EV batteries for grid storage through vehicle-to-grid (V2G) technology.
In conclusion
The energy transition in Europe represents a monumental effort to combat climate change and create a sustainable energy future. The integration of renewable energy sources is a crucial step in this journey, but their intermittent nature presents challenges that must be addressed. Lead batteries, together with other technologies, emerge as the silent protagonists, providing a robust and reliable energy storage solution. From enhancing grid stability and enabling renewable integration to empowering decentralized energy systems and fostering electric vehicle adoption, lead batteries will play a multifaceted role in reshaping Europe's energy landscape. As technology advances and costs continue to decline, the potential of batteries will only grow, propelling Europe towards a cleaner, greener, and more resilient energy future.
The lead battery industry could be in line for a $10 billion share of the burgeoning energy storage market within the next decade.
Research into upcoming projects and opportunities indicated that the ESS landscape is forecast to be 550GWh by 2030 with a value of $30-$50 billion for all battery technologies.
The lead battery industry has set its sights on securing 100GWh of that potentially lucrative ESS market.
CBI launched its first technical roadmap in 2019 setting specific goals for the end of 2022.
“It was all really market-driven. We used those targets to select our program. And the result of the
projects that we funded have pretty much shown that we delivered on these goals that we set.”
There are now batteries on the market, primarily from our members in the US and Asia, that meet that criteria.
This means there are now have advanced lead batteries on the market-oriented toward ESS that have an impressive globalized cost of ownership for the system, says Raiford.
“The way we view it as battery scientists is cycle life — most key stakeholders look at it from total cost of ownership.
“So we see stationary batteries now that really perform along the lines of lithium.”

The Consortium for Battery Innovation connected with over 730 attendees from 42 different countries representing 319 different organizations in Siem Reap, Cambodia for the 20th Asian Battery Conference (20ABC) and the Recycle 100 International Secondary Lead Conference and Exhibition that featured global discussions on the world of lead, recycling, lead-acid batteries and energy storage.
CBI Senior Technical Manager, Dr. Matt Raiford said that lead batteries are made and produced in over 100 countries, and the Asian Battery Conference was a great venue to see how Asia, Africa, and other areas of the world are innovating and improving lead battery technology. For instance, CBI member companies, Hammond and Borregard, demonstrated deeper understandings of additive chemistry as a low threshold method to improve lead batteries for many different applications.
CBI participated in the line-up of over 45+ conference speakers during 20ABC to share our technical battery knowledge and insights with attendees with presentations that included:
The 20th Asian Battery Conference provided a chance to join several technical sessions providing valuable insights from industry leaders, market analysts and technical experts about the lead battery industry. Several speakers including CBI member companies presented innovations and advancements, such as new active material formulations and improvements in the manufacturing process, for several applications of lead batteries.
Dr. Begüm Bozkaya, CBI’s Technical Manager, shared that there are definitely future opportunities for lead battery technology in Asia and other continents of the world via the implementation of new developments to deliver cost-efficient, safe, and sustainable battery solutions.
8th International Secondary Lead & Battery Recycling Conference covered several aspects of lead recycling industry in Asia and Africa. Bozkaya shared that many of the speakers addressed the current issues related to environmental challenges, financial, and social risks in the secondary lead industry. It was beneficial for attendees as some of the ILA & CBI members also illustrated their new techniques and developments in recycling of lead batteries.
Recycle 100 illustrated the ins and outs of running battery recycling centers - the heart of lead battery sustainability. Raiford was intrigued by ongoing improvements at Asian recycling operations, especially in increasing recycling efficiency - and how these improvements were presented to representatives from dozens of countries.
The city of Siem Reap, Cambodia was an amazing host and we enjoyed seeing all the beautiful areas in that region. The 20ABC was a successful event from all angles – including the achievement from the event’s charity initiative. The "ONE Minute Giveback", exceeded organizer’s and sponsor Sorfin Yoshimura’s expectations, by raising over $22,000.00 USD to help fund a bed in the Oncology Department of Angkor Hospital for Children.
We look forward to next year’s events and continuing the technical conversations around lead batteries.
As part of the knowledge economy, individuals with a Ph.D. desire an in-depth knowledge within a specific field. To begin this journey, all Ph.D. or Doctor of Philosophy candidates must have very specific criteria to enter the doctoral program including a masters degree, letters of recommendation, and a statement of purpose that describes why they are seeking a PhD, what they have done so far to prepare themselves, and what goals they plan to achieve later.
For Begüm Bozkaya, her pursuit of a doctoral degree program was a way to explore advancements, provide more areas for career opportunity and continue to grow professionally.
Because of her appreciation in the study of electrochemistry during grad school that focused on batteries including Li-ion and carbon research, Fraunhofer Institute approached her about a position to work on advanced lead acid batteries. The opportunity was for more than just a Ph.D., as it was a complete package that involved a paid position on industrial projects. The program through Fraunhofer kept Bozkaya busy working on various carbon related industry projects, participating in networking and conferences, interacting with the lead battery industry, and of course spending time on her own studies.
“It’s important to network just as much as it is to allow time for your personal and social life,” Bozkaya said reflecting on her work-life balance. “You need to keep the bigger picture in mind. I recommend networking to help you widen your perspectives by meeting new people to collaborate with. During this time, she recommends shaping and structuring your thesis.
Bozkaya describes the path to her Ph.D. with a range of emotions and ultimately perseverance in overcoming a program that challenges you each day. She explained that there was a period toward the end of the program where her work was consuming, her ability to find focus time to write was limited, and she began to feel overwhelmed. She thought about quitting.
Instead, she found the motivation to keep going by just doing a little more each day.
“When you feel like you don’t want to continue in the program, give yourself one more push. You owe it to yourself. Then you will start to see how those little steps will move you forward. And the result will be rewarding.”
Her advice for anyone entering a doctoral program is to believe in yourself.
She warned that at some point you may start to feel overwhelmed for any number of reasons, and you might want to reconsider the research path. “That is the time to really lean into the support from your friends, family and colleagues,” encouraged Bozkaya.
That support and effort paid off and finally put her over the hump. And along with encouragement from both an old colleague and her family, Bozkaya could finally grasp her goal.
“The day of my defense was filled with emotion because of all the ups and downs it took to get this point,” said Bozkaya.
She completed her defense with an excellent score - a 1.0!
After an academic journey that started with a Bachelors in Chemistry, then a Masters of Materials Science, Begüm Bozkaya finally defended her Ph.D. thesis entitled, “Influence of Carbon Additives on the Electrochemical Performance of Modern Lead-Acid Batteries” on May 10, 2023.
Now Bozkaya continues her interest in materials science and batteries. In 2021, she was offered a role as Technical Manager for the Consortium for Battery Innovation. Bozkaya works with colleagues to secure EU funding projects and is responsible for CBI’s technical program in Europe – including workshops and conferences. Catch one of her presentations at an upcoming CBI conference and be sure to congratulate her on the new doctorate.
The CBI 2023 Techincal and ALBA Workshops were held on June 13-15, in Wolfsburg, Germany.
A solar and lead battery-powered tractor, that is being developed as a farming solution for Africa, was named a semifinalist for the Milken–Motsepe Prize in Green Energy. The competition rewards projects who expand access to reliable, affordable, and sustainable electricity in Africa.
AfTrak or Africa Tractor, is a prototype program funded by Innovate UK as part of its Energy Catalyst Round 9. The program was one of 20 teams selected to advance to the Semifinalist Round for a competition by the Milken Institute and the Motsepe Foundation. Semifinalists receive $20,000 for the continued development and testing of their designs, as well as complimentary access to a Stanford Online course to help build their businesses.
AfTrak was selected from over 160 entrants around the world, in over 36 countries.
This potentially revolutionary tractor design, featuring lead batteries, is an African farming project created in collaboration between the Consortium for Battery Innovation (CBI), UK- & Malawi-based charity Tiyeni, and Loughborough University.
“We are delighted to be selected as a semifinalist in this prestigious competition—a reflection of the inspiration and technical capabilities of the Loughborough and Tiyeni teams. It’s also a great indicator of CBI’s ambitions.” said Carl Telford, Senior R&I Manager at CBI.
Across large areas of Malawi, under the few inches of topsoil, there is a heavily compacted layer of rock-hard earth through which plants cannot penetrate. Tiyeni has created an innovative agricultural method called Deep Bed Farming (DBF). The tractor, being developed at Loughborough University, will be a low-cost, hand-operated, solution for farming in the difficult soil.
The proposed AfTrak project is a micro electric tractor capable of mechanizing land preparation in line with Tiyeni’s Deep Bed Farming to prepare soil to a depth of 400mm.
For this program, AfTrak aims to provide an affordable green energy solution in sub-Saharan Africa, utilize a solar array and lead battery system to power micro electric tractors for Deep Bed Farming, and create a self-sustaining model for decentralized energy access.
An independent panel of expert judges determined the 20 teams receiving funding. Moving forward in the competition involves semifinalist teams demonstrating the effectiveness of their ideas in field tests.
They will be evaluated for their ability to:
After the Semifinalist Round, judges will select five finalist teams to conduct another round of field tests in Africa. Then in May 2024, the judges will award a $1 million Grand Prize. A Runner-Up Prize of $250,000 will also be awarded.
The Milken Institute is a nonprofit, nonpartisan think tank focused on accelerating measurable progress. They bring together the best ideas and innovative resourcing to develop blueprints for tackling critical global issues.
The Milken–Motsepe Innovation Prize program is a series of multiyear, multimillion-dollar innovation competitions for technological solutions that accelerate progress toward the UN Sustainable Development Goals (SDGs).
One of the two innovation competitions in the program, the Milken–Motsepe Prize in Green Energy, aims to expand access to reliable, affordable, and sustainable electricity in Africa as an essential factor in achieving long-term economic growth and shared prosperity. The competition advances progress toward SDG 7 (ensuring access to affordable, reliable, sustainable, and modern energy for all).
The semi-finalists were announced on June 6, 2023.

A ground-breaking new battery ‘match’ service is set to help utility companies choose the most suitable batteries as partners for their energy storage schemes.
CBI Battery Match has been designed and built by the Consortium for Battery Innovation (CBI) – the global advanced lead battery research group – to help electricity providers and other energy storage projects find a battery system that best meets their requirements.
The online service, launched in conjunction with the Energy Storage Association’s Virtual Conference (ESACon20), is targeted at systems specifiers and integrators for utility and renewable energy companies and presents them with a series of potential battery partners, before linking them directly with battery manufacturers.
Just like human dating apps, users tap in information about themselves together with details of their expectations and requirements. Using an intelligent algorithm based on battery industry expertise, a range of battery solutions best suited to their needs are identified in real-time.
Dr Alistair Davidson, Director of CBI said: “We’re aiming to bridge the gap between utilities and renewable energy providers and battery manufacturers by demonstrating the wide range of reliable, high-performance advanced lead batteries available.
“Our research Consortium of battery manufacturers has found that their customers needed a simpler way to sort through the range of choices to identify the best battery for their energy storage system.
“Our battery matchmaker will help demonstrate that there are a range of options available, where advanced lead batteries are best-suited to their needs, that allows them to find a tailor-made solution for their specific system.”
“We’re seeing massive growth in demand for battery energy storage across the globe which means we need many more batteries. This new tool helps users consider the range of potential solutions and puts them in touch with potential partners in the shape of the manufacturers.”
With the energy storage market expected to grow at nearly 25% in the next five years, batteries will be one of the key energy storage technologies.
“All battery chemistries will have a part to play achieving future clean energy targets.” added Dr Davidson. “One of the advantages of using advanced lead batteries is that they combine reliability, high technical performance and cost-effectiveness with a recycling rate of almost 100% in North America and Europe.”
The technology is already widely used by utility and renewable energy companies for projects ranging from large-scale peak-shaving and frequency regulation projects to microgrids and off-grid systems.
The battery match service is a collaborative effort between the lead battery industry and CBI, which brings together robust, technical information from some of the leading global players in one place. Companies including Advanced Battery Concepts, C&D Technologies, East Penn Manufacturing, Electric Applications Incorporated, EnerSys, Exide Technologies, Gridtential, NorthStar Battery and Trojan Battery Company are engaged in the project.
With a user-friendly interface available on desktop and mobile, energy storage end-users can log on to the tool, input their system requirements, and the outcome is a direct match with the battery best suited for their project. CBI Battery Match will enable direct communication between the energy storage company and the battery manufacturer, a streamlined process where inputted information results in the output of a battery.

CBI invited member company RSR Technologies, a unit of ECOBAT Technologies, to share their research focus relating to lead batteries and energy storage
By: Travis Hesterberg (RSR Technologies), Tim Ellis (RSR Technologies and Chairman of CBI) and Matt Raiford (formerly RSR, now CBI)
Lead batteries offer a unique cross section of performance, cost, and sustainability. These advantages are accessed because of the very materials that make up lead batteries, mainly lead, plastic and electrolyte. However, performance enhancement in lead batteries must keep pace with the added requirements demanded by an increasingly energy storage dependent world. RSR Technologies’ view of this issue is the best way to change how lead batteries perform is to start from the very beginning: lead.
Alloy developments have been the hallmark of RSR Technologies, and research is centered on producing alloys for the needs of today and tomorrow. Current research efforts use highly resolved materials characterization techniques, such as the Advanced Photon Source at Argonne National Laboratory, to monitor the fundamental growth and dissolution processes that occur in lead batteries and understand how our alloy developments can change these processes for the better.
The role of common elements found in lead alloys on the growth and crystal habit of the many species (PbSO4 and PbO2 for instance) in lead batteries is not understood. Each element has an effect and we are studying how each can benefit or limit the dynamic charge acceptance and cycle life of lead active material. For instance, electron microscopy has shown that the PbSO4 crystal behavior can change drastically based on the elements present in the active material or electrolyte.
The slow dissolution behavior of PbSO4 is of key importance due to its negative effect on charge acceptance and cycle life. The focus on PbSO4 crystal behavior has been fruitful, yielding a new alloy for higher performing lead battery active material, SUPERSOFT-HCYCYLE®. Trace elements in this alloy help govern the crystallization of PbSO4 in the positive and negative electrode. Smaller PbSO4 crystallites with a more easily dissolved crystal habit are formed using SUPERSOFT-HCYCYLE®. The faster dissolution in turn facilitates high charge acceptance and cycle life.
This is just the tip of the iceberg. As we push forward, others are as well. Benefits from SUPERSOFT-HYCYCLE® can be interwoven with the performance enhancements offered by additives, carbon containing and carbon-based electrodes, and bi-polar batteries. All these enhancements working together completely reform the lead battery, advancing the technology to the requirements of the future.
Engineers from European car companies met in Bruges, Belgium, to explore advances in lead battery technology specific for future low emission vehicles.
The workshop, organized by the Consortium for Battery Innovation (CBI) in co-ordination with CENELEC, the European Committee for Electrotechnical Standardization, brought together nearly 100 global technical experts from across the advanced lead battery and automotive industries on 22 and 23 May.
Advanced lead batteries already enable start-stop technology which has helped cut emissions from cars in Europe and the US by up to 10%.
Now, engineers hope to reduce heat and water loss and improve battery performance further as they prepare the next generation of low emission vehicles.
Delegates from around the globe arrived in Bruges to attend the EFB & Heat technical workshop, exploring high-temperature durability tests for advanced lead 12 V batteries.
The benefits of carbon additives have been widely studied and been shown to improve dynamic charge acceptance (DCA) of lead batteries. However, current test standards indicate that the increased use of carbon for micro and mild-hybrids may result in high-temperature durability issues.
Lead batteries are the dominant automotive battery technology, with virtually every vehicle on the road today containing a lead battery. Automotive market dominance has been maintained through recent performance improvements that have been spurred by research and innovation by the lead battery industry, which has included studies into a range of additives such as carbon.
Encouragingly, recent research conducted by CBI members under real-world conditions has indicated that the side effects of carbon additives may be significantly overestimated and may be a result of the ways in which batteries are tested.
Significant new opportunities in micro and mild-hybrid vehicles are available for lead battery technology if these issues can be addressed and overcome through continued research, innovation and collaboration within the industry.
Following successful meetings in Eberbach and Alcalá, the workshop in Bruges facilitated the interaction between OEM engineers and lead battery scientists from around the world to work and plan collaborative projects and experiments focused on exploring high-temperature durability improvements and water loss mechanisms in lead batteries.
A series of plenary talks outlined current and possible methods used to continue improvement in advanced lead battery technology. Water loss mechanisms, new gas monitoring instrument development, research methods for new additives, and new tests developed to study these issues were just some of the topics covered in the intensive 2-day technical workshop.
The lead battery industry, through collaborative CBI technical workshops such as the EFB & Heat workshop, is continuously researching and striving to improve and innovate in lead battery technology to meet the future demands of automotive applications. The workshop in Bruges is the latest partnership between CBI, CENELEC and the European car industry to support lead battery innovation.
The work of CBI and its members does not end in Bruges. Working groups have been established in collaboration with important industry organizations to focus on unique issues that will be developed over the coming year. The lead battery industry will continue to research and innovate to propel automotive lead battery technology into the future.
Two CBI members, Narada and Microporous, have been acknowledged as ‘honorable mentions’ by the judging committee at the U.S. annual Battery Council innovation awards.
Narada has partnered energy storage operator Upside Group in an innovative frequency regulation project, which represents the first large-scale application of lead-carbon batteries in grid-level frequency regulation energy storage systems.
The project was for the German power grid (see the CBI case study here) and the installation, at Langenreichenbach, has a planned construction capacity of 75MW. The installed capacity of the first phase of the project is 16.4MW, and the peak energy storage capacity can reach 25MWh. This project consists of 18 containers, and the battery consists of 10,584 units of 1200Ah lead-carbon valve regulated cells. It is powered by nine inverters, each of which can provide 1.8 MVA.
Narada was one of the pioneers in terms of developing lead-carbon battery systems in energy storage. The company says this project is the first investment and operation model project in the overseas market.
Narada chose Germany as a test location because its utilization of renewable energy is one of the most advanced in the world. Its power grid frequency regulation market is thus a mature power market auxiliary service trading market.
Narada’s project development team was responsible for the finance and development of the entire project. Narada will work with Upside to finish building the project, with a total investment of around €42 million ($47 million).
Meanwhile, the awards committee said that separator product developer Microporous’ innovation — a product known as the DCA Booster Mat — provides greater dynamic charge acceptance without needing any change for the negative active material in the battery.
The Booster Mat can be bundled with the firm’s SLI or industrial separators and is suitable for enhanced flooded batteries — meaning that it allows charge acceptance optimization in high rate partial state of charge requirements (such as in start-stop applications).
Microporous hopes to have completed prototype testing in the next 12 months. It will then develop partnerships with battery companies to evaluate and market the product.
Divya Tiwari, Technical Manager at Microporous, said the innovation offers excellent charge acceptance in industrial markets such as motive power, where opportunity charging is required.

A digital map detailing more than 120 lead battery-powered energy storage projects has been unveiled by the Consortium for Battery Innovation (CBI).
The map, published online ahead of the Energy Storage Association’s annual conference held in Phoenix, Arizona, includes diverse case studies demonstrating successful lead battery energy storage installations from the United States, to Asia and Europe.
The feature is included on the Consortium for Battery Innovation’s website.
Through a range of case studies, the map details how lead battery storage is supporting utility and renewable energy systems. This includes providing back-up for local power grids and supplying off-grid electricity to power remote communities.
CBI Director Dr Alistair Davidson said: “We are seeing growing interest in lead battery energy storage for utility and renewables systems all over the world. The aim of this initiative is to highlight some of these installations and encourage companies to share other examples we can highlight demonstrating the variety of projects currently in place.”
“Our analysis suggests demand for battery energy storage will increase significantly in the next five years. This new tool will allow us to demonstrate that the latest lead battery technology is supporting a wide range of installations with reliable, safe, sustainable and cost-effective energy storage.
“A focus of CBI is to conduct pre-competitive research to support development of the next generation of lead batteries which will significantly extend both battery life and performance, to support diverse energy systems and electrification.”
