Eos’s core innovation is its proprietary Znyth™ aqueous zinc battery technology engineered for safety, durability and environmental impact. Its non-flammable aqueous electrolyte and domestically sourced zinc enable broad temperature tolerance, 3–12-hour discharge and 20+ year lifespan. Manufacturing at Eos Ingenuity Park in Turtle Creek, Pennsylvania uses an automated line with 98% efficiency and over 80% domestic materials for competitive lifecycle costs.
Flagship products include the Eos Cube, Eos Z3™ and modular systems such as the Eos Stack and Eos Hangar, offering scalable, cost-effective energy storage solutions with lifespans exceeding two decades, designed to mitigate solar and wind intermittency, manage peak demand and provide emergency power.
Late 2024 deployments include energy storage systems at Naval Base San Diego and Marine Corps Base Camp Pendleton for mission-critical power resilience. Partnerships include integrated stationary storage systems with FlexGen and a supply chain MOU with Wabash Resources. Production capacity was increased from 1.25 GWh to 2 GWh with plans for an additional 6 GWh expansion.
