Eos Energy Enterprises (NASDAQ:EOSEW) is a U.S.-based energy storage technology company developing and manufacturing advanced battery systems for grid-scale and commercial applications. The company focuses on providing reliable, long-duration energy storage solutions that help utilities, independent power producers and commercial customers balance generation and demand while integrating renewable energy sources such as wind and solar.
The company’s core offering is built around its proprietary zinc hybrid cathode (Znyth) battery architecture, which uses safe, non-flammable aqueous electrolytes and earth-abundant materials. Eos combines its battery cells with power conversion systems, controls software and balance-of-plant components to deliver turnkey energy storage solutions. These integrated systems are designed for multi-hour storage durations, modular scalability and reduced installation costs compared with conventional lithium-ion alternatives.
Founded in 2008 and headquartered in Edison, New Jersey, Eos Energy Enterprises went public in 2021 to accelerate commercialization of its storage technology. The company operates a research and development center in New Jersey and has established a manufacturing facility in West Virginia to support growing demand for its battery systems. Eos is led by co-founder and chief executive officer Joe Mastrangelo, who has guided the company from its early technology development phase through its recent expansion into large-scale deployments.
Eos serves customers across North America, targeting utility grid operators, commercial and industrial energy users, microgrid developers and renewable energy project owners. By delivering long-duration, cost-effective storage solutions, Eos aims to help its clients enhance grid resilience, lower levelized energy costs and support the transition to a more sustainable energy ecosystem.
