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.
ESS Inc. designs, builds and deploys environmentally sustainable, low-cost, iron flow batteries for long-duration commercial and utility-scale energy storage applications requiring from 4 to 12 hours of flexible energy capacity. The Energy Warehouse™ and Energy Center™ use earth-abundant iron, salt, and water for the electrolyte, resulting in an environmentally benign, long-life energy storage solution for the world’s renewable energy infrastructure. Established in 2011, ESS Inc. enables project developers, utilities, and commercial and industrial facility owners to make the transition to more flexible non-lithium-ion storage that is better suited for the grid and the environment.
Energy Center™ product line launched
Our technology delivers environmental and cost advantages. Specifically, our non-corrosive, non-toxic chemistry enables use of off-the-shelf materials. Its non-flammable composition eliminates costly fire suppression systems. Combined with an innovative cell design, our customers benefit from increased power density and reduced O&M cost over our platform’s 20+ year lifespan.
With its safe, earth-abundant, 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.
