Eos Energy Enterprises, Inc. is a leading provider of zinc-based energy storage solutions, dedicated to accelerating the global transition to clean energy. The company designs, develops, manufactures, and markets its battery energy storage systems (BESS) for utility-scale, microgrid, and commercial and industrial applications.

At the core of Eos's offerings is its proprietary Znyth™ aqueous zinc battery technology, which includes products like the Eos Indensity architecture, Eos Cube, and the Z3 battery module.
