Eos Energy Enterprises, Inc.

Eos Energy Enterprises, Inc. is an American energy company that designs, manufactures, and provides zinc-based battery energy storage systems (BESS). These systems are sourced and manufactured in the United States and serve as alternatives to lithium-ion batteries. Eos BESS are designed for utility-scale, microgrid, and commercial and industrial long-duration applications. The company develops, manufactures, and markets these zinc-based energy storage systems. Eos has an intellectual property portfolio, including patents for its battery chemistry, mechanical product design, energy block configuration, and its proprietary Battery Management System (BMS). The BMS uses Eos-developed algorithms, ambient and battery temperature sensors, and voltage and current sensors for monitoring. The company currently focuses on manufacturing and selling turnkey direct current (DC) battery energy storage systems and plans to expand to include turnkey alternating current (AC) systems. Primary applications for Eos systems include integration with grid-connected and non-grid-connected renewable energy systems, deployment in systems to relieve grid congestion, and installations for commercial and industrial customers to reduce peak energy usage or participate in utility markets. The company operates a manufacturing facility in Turtle Creek, Pennsylvania, which produces DC energy blocks with the BMS. Eos also has a facility in Warrendale, Pennsylvania, which is not currently operational but is expected to become operational in 2026.
