ESS, Inc.

Established in 2011, ESS Inc. manufactures low-cost, long-duration all-iron redox flow batteries for commercial and utility-scale energy storage applications requiring 4+ hours of flexible energy capacity. Its product, Energy Warehouse™, uses iron, salt, and water for the electrolyte, and delivers an environmentally safe, long-life energy storage solution for the world’s renewable energy infrastructure.

Based in Wilsonville, Oregon, ESS Inc. was founded by a team with deep experience in fuel cells, electrochemistry, advanced material science and renewable energy. After five years of intensive innovation, engineering development and rigorous testing and validation, with the backing of ARPA-E and others, the company began shipping turnkey energy storage solutions in 2015.

In 2017, BASF, the world’s leading chemical company, became a significant investor in ESS Inc., joining forces to deliver energy storage solutions for a sustainable future.

With its safe, proven and earth-abundant all-iron flow battery, ESS is helping project developers, utilities, and EPCs make the transition to more flexible non-lithium-ion storage that is better suited for the grid in a variety of applications.
