Our Mission:
At ESS Inc., our mission is to bring to market the cleanest, lowest-cost long-duration energy storage systems. We are the catalyst for a sustainable energy future.

Our History:
ESS Inc. was founded in Portland, Oregon in 2011 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 that allowed companies and municipalities to control their own energy future in 2015.

ESS Inc. manufactures low-cost, long-duration iron flow batteries for commercial and utility-scale energy storage applications requiring 4+ hours of flexible energy capacity. Its product, the Energy Warehouse™ (EW), 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.

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, earth-abundant, proven all-iron flow battery technology, 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 and the environment.
