Eos Energy Enterprises, Inc. is a New Jersey-based energy storage company founded in 2008, dedicated to advancing zinc-based battery technology for long-duration energy storage (LDES). The company designs and manufactures safe, sustainable solutions to support energy independence in the U.S., with a focus on grid resilience and renewable energy integration.
Eos’s flagship products—including the Eos Cube, Eos Z3™, and modular systems like the Eos Stack and Eos Hangar—serve utilities, commercial businesses, and governmental entities, addressing challenges such as solar and wind intermittency, peak energy demand, and emergency power supply. By emphasizing American manufacturing at its Pennsylvania facility, Eos aims to reduce dependency on foreign materials while providing scalable, cost-effective storage systems with lifespans exceeding two decades.
Battery Technology
Eos’s core innovation is its proprietary Znyth™ aqueous zinc battery technology, engineered to outperform conventional lithium-ion systems in safety, durability, and environmental impact. Zinc is sourced domestically, and its aqueous electrolyte design avoids flammable components, eliminating fire risks and simplifying installation requirements. The technology’s broad temperature tolerance and recyclable materials—alongside a 20+ year operational lifespan—make it suitable for long-duration storage (3–12-hour discharge).
Manufacturing occurs at Eos’s Eos Ingenuity Park in Turtle Creek, Pennsylvania, where an automated production line now achieves 98% efficiency and yields systems priced competitively. Material costs are further reduced by utilizing locally available, low-cost metals (over 80% sourced domestically), enabling Eos to offer lifecycle costs ($LCOS) advantages over lithium-ion technologies.
Recent Projects
In late 2024, Eos delivered energy storage systems to Naval Base San Diego and Marine Corps Base Camp Pendleton, providing mission-critical power resilience through grid backup and renewable integration. These projects exemplify Eos’s role in enhancing national security through reliable, domestically produced solutions.
A partnership with FlexGen launched integrated stationary storage systems for utility-scale projects, while a Memorandum of Understanding (MOU) with Wabash Resources aimed to bolster U.S. supply chain resilience for zinc battery manufacturing. Eos also expanded production capacity, raising its initial manufacturing output from 1.25 GWh to 2 GWh, with plans to add 6 GWh more by scaling facility expansion.
Investors
Eos has secured significant investments to fuel its growth, including a strategic $315.5 million commitment from Cerberus Capital Management LP and a $303.5 million loan guarantee from the U.S. Department of Energy’s Loan Programs Office. As a publicly traded company on NASDAQ under ticker EOSE, Eos attracted $75 million in initial gross proceeds in mid-2024 and a $210.5 million Delayed Draw Term Loan, alongside restructuring $100 million in debt. Its financial strategy balances strategic partnerships with public market access to scale production and advance its technology.
