The US Department of Energy’s (DOE) Loan Programs Office (LPO) has announced a long-duration energy storage (LDES) sector “conditional commitment for an up to $398.6 million DOE loan guarantee to Eos Energy Enterprises (Eos) for construction of four manufacturing lines to produce next generation utility- and industrial-scale zinc bromine battery energy storage systems (BESS) in Turtle Creek, Pennsylvania.”
This so-called grid-scale storage allows utilities and industrial customers to store clean energy when there is a surplus. They can then it when energy is relatively more expensive or clean power is unavailable. “Making technologies like these are a crucial part of making our grid more reliable, flexible, and affordable for all Americans,” DOE said.
If finalized, the project is expected to manufacture more than 8 GWh of storage capacity annually by 2026. This is enough to provide electricity to ~300,000 average U.S. homes instantaneously or to meet the annual electricity needs of ~130,000 homes if fully charged and discharged every day. The project is expected to create up to 50 union contractor construction jobs and as many as 650 new operations jobs when at full operational capacity.
This is part of the Biden Administration’s awakened and, well, enlightened agenda to onshore and re-shore domestic manufacturing of critical technologies such as battery electric energy storage systems that are essential to building a clean energy future and strengthening America’s energy security. “Using the loan authority from the President’s Inflation Reduction Act, the LPO is impelling billions in public-private investments to boost the nation’s competitiveness, strengthen supply chains, and create good-paying jobs to power the clean energy economy,” DOE said.
Investing in America is a key pillar of Bidenomics by growing the American economy from the bottom up and middle-out – from rebuilding the nation’s infrastructure, to creating a manufacturing and innovation boom powered by good-paying jobs that don’t require a four-year degree, to building a clean-energy economy that will combat climate change and make our communities more resilient.
Today’s energy storage market is nascent but rapidly growing and is dominated by lithium-ion and lithium iron phosphate battery technologies, which typically serve short-term duration applications of approximately 4 hours.
Eos’s zinc-bromine Eos Z3™ batteries provide alternative battery chemistry to lithium-ion, lead-acid, sodium-sulfur, and vanadium redox chemistries for stationary battery storage applications.
Eos’s technology is also specifically designed for long-duration grid-scale stationary battery storage that can assist in meeting the energy grids’ growing demand with increasing amounts of renewable energy. Critically, Eos batteries are non-flammable and do not require active cooling to operate. The batteries can achieve 100% depth of discharge, do not degrade based on age, and are rated for 6000 charge/discharge cycles (~20 years of use) before degradation. Eos already manufactures a zinc-bromine battery. If finalized, LPO financing will help develop the next-generation battery system, the Eos Z3, which is forecast to be more energy dense and cost-efficient to produce than Eos’s previous models.
The project’s intellectual property is based in the United States. Moreover, Eos over time expects to source nearly 100% of the materials supply for the Eos Z3 battery from the United States. The product is also insulated from market volatility and supply chain risk that challenge other battery chemistries by forgoing scarce critical minerals such as lithium, which are largely imported.
Additionally, grid-scale storage will allow utilities and industrial customers to store clean energy when there is a surplus and use it when energy is relatively more expensive or clean power is unavailable. BESS can provide numerous grid functions, including an alternative to fossil-fuel electricity generation during demand spikes, being a lower-cost option during normal demand, and providing backup power.
The jobs created by the project would be based primarily in Turtle Creek, Pennsylvania, with hourly wages paid at least at the prevailing wage and competitive internship and apprenticeship salaries. In addition, LPO said it works with all borrowers to create good-paying jobs with strong labor standards during construction, operations, and throughout the life of the loan including developing strong Community Benefits Plans.
Eos began community outreach efforts in 2022 to economic and workforce development leaders, educational institutions, and state and local governments – including Allegheny Conference on Community Development and its economic development affiliate the Pittsburgh Regional Alliance, The Heinz Endowment and The Mon Metro Chamber of Commerce, among others – to ensure community engagement in the project and to attract a strong local workforce.
Eos has created a Clean Energy Careers Program to target local high schools, vocational schools, and trade schools to attract students to apprenticeship opportunities; to provide internship opportunities for 2- or 4-year college and high school students to learn skills from Eos welders, chemical engineers, and other professionals, opening up potential long-term career pathways for those students; and to raise awareness of career opportunities at Eos with local veteran groups, literacy centers, and within the nonprofit community.
Turtle Creek and nearby communities are DOE-identified disadvantaged communities (DACs), and the project is situated on a former Westinghouse Electric Corporation campus. The company’s current workforce is diverse across race, gender, and veteran status, and Eos is committed to growing its diverse, equitable, and inclusive team. The project’s support for overburdened and underserved communities and their workers aligns with the Biden-Harris Administration’s to ensure at least 40% of the benefits of federal clean energy investments go to DOE-identified DACs.
The LPO financing would be offered through LPO’s Title 17 Clean Energy Financing Program, which includes financing for innovative energy and supply chain projects like Eos’s and certain state-supported projects and projects that reinvest in existing energy infrastructure.
While this conditional commitment demonstrates the Department’s intent to finance the project, several steps remain for the project to reach critical milestones, and certain technical, legal and financial conditions must be satisfied to the satisfaction of DOE before the Department enters into definitive financing documents and funds the loan.
