Eos Energy Enterprises (NASDAQ:EOSE) is a technology-driven energy storage company specializing in long-duration battery systems designed to support grid resiliency and renewable integration. Founded in 2008 as a spin-out from the Gas Technology Institute, Eos has developed its proprietary Znyth® battery platform that combines aqueous zinc-based chemistry with a non-flammable electrolyte. The company’s modular systems are engineered for utility-scale, commercial and industrial applications, delivering dispatchable power, frequency regulation and peak-shaving capabilities without relying on scarce or toxic materials.
At the core of Eos’s offering is the Znyth® 1.5 and 4.0 battery modules, which employ low-cost zinc metal electrodes and a patented cathode formulation. These systems are designed to provide multi-hour, cyclical energy storage at a competitive total cost of ownership, helping utilities, microgrid operators and renewable developers manage intermittency and maintain grid stability. Eos’s design emphasizes safety, scalability and simplified operations, with the potential for rapid deployment in both new and existing infrastructure.
Headquartered in Edison, New Jersey, Eos Energy Enterprises operates a manufacturing facility for its Znyth® modules and maintains engineering and development centers to advance grid-scale storage innovation. The company serves customers primarily in North America, partnering with utilities and energy services providers to tailor energy storage solutions to regional regulatory frameworks and market requirements. Through strategic alliances, Eos is extending its technology into emerging markets where reliable, long-duration storage can accelerate the shift to cleaner energy sources.
Under the leadership of CEO Joe Mastrangelo, Eos Energy Enterprises has focused on scaling manufacturing, optimizing its supply chain and securing project pipeline growth. The management team brings extensive experience in battery development, utility operations and project finance, positioning the company to capitalize on the global transition toward distributed and renewable energy resources. Eos continues to advance its technology roadmap, aiming to enhance system energy density, extend operational life and reduce overall storage costs for a sustainable energy future.
