Among our nation’s most powerful strategies for tackling climate change are electrifying transportation and accelerating clean power generation. Both these strategies have one essential thing in common: their success depends on advancements in battery technologies. Economical and fast-charging batteries are key to spurring adoption of all-electric and plugin-hybrid vehicles, while high-energy-density battery storage is needed to address the intermittency of solar and wind power and make the grid more responsive.
At EERE, our research and development investments throughout the past decade have yielded breakthroughs in battery cost and performance, while driving down weight and enhancing manufacturability. Now, in collaboration with other DOE Offices as well as other federal agencies, we are building on this track record to inspire new advances in batteries and further the journey toward a clean energy future. Today, on National Battery Day, I want to highlight the innovative and impactful work under way at EERE to topple technology barriers and speed market transformation.
EERE and Partners Leading the Charge
EERE is committed to ensuring that advances in battery technologies benefit everyone. To accomplish this, efforts are underway to reduce the cost, volume, and weight of batteries, while simultaneously improving the batteries’ performance (power, energy, and durability) and ability to tolerate abuse conditions. Accomplishing these goals will require a series of strategies and initiatives, working with partners who share the vision of what batteries are capable of.
One key effort is the Federal Consortium for Advanced Batteries (FCAB), which provides a framework for cooperation and coordination among federal agencies having a stake in developing advanced battery technology and establishing a domestic supply of lithium batteries. In addition to DOE, FCAB includes the Departments of Commerce, Defense, and State. Each agency contributes its strengths towards a shared commitment to utilizing advanced batteries as a means of combatting climate change.
Within DOE, EERE is co-chair of the Energy Storage Grand Challenge (ESCG), a comprehensive program to accelerate the development, commercialization, and utilization of next-generation energy storage technologies. Launched in 2020, the ESGC is also co-chaired by the Office of Electricity, and includes the Office of Science, Office of Fossil Energy, Office of Nuclear Energy, Office of Technology Transitions, ARPA-E, Office of Policy, the Loan Programs Office, and the Office of the Chief Financial Officer. Recently, the ESGC released the ESGC Roadmap, which set the goal of developing and domestically manufacturing energy storage technologies that can meet all U.S. market demands by 2030. The Roadmap set aggressive cost targets representing a 44 percent reduction from current battery costs, laying the foundation for more cost-competitive electric vehicles and potentially benefitting the production, performance, and safety of batteries for stationary applications.
Battery Recycling and Critical Materials
Critical materials — including rare earth elements with unique magnetic, catalytic, and luminescent properties — are key resources needed to manufacture products for the clean energy economy, including wind turbines, solar panels, electric vehicles, and energy-efficient lighting. However, supply chain disruptions and price fluctuations associated with these valuable resources introduce uncertainty and instability in the production of these essential technologies. In the case of lithium-ion batteries, for example, reliable supplies of lithium and cobalt are vital to the manufacturing of products used for electric vehicles and grid energy storage.
DOE employs diverse strategies to address critical materials challenges. One important…
