ESS Announces Grid-Scale Storage Solution

ESS Inc, the Wilsonville, OR-headquartered manufacturer of a flow battery using iron and saltwater electrolytes, has launched a new range of energy storage systems starting at 3MW power capacity and promising 6-16 hours discharge duration.

The company announced the launch of the ESS Inc Energy Center last week, a containerised utility-scale energy storage product aimed at serving front-of-the-meter use cases as well as larger commercial and industrial (C&I) site applications. Based on ESS Inc’s second generation of flow battery modules, the solution is designed to support large-scale renewable energy projects, serve transmission and distribution (T&D) applications and supply peaking energy capacity to replace peaker gas plants.

ESS developed its groundbreaking "all iron" flow battery technology with support from ARPA-E and ONAMI.  The ESS technology combines lowest cost long-duration storage with leading edge cycle life and minimal environmental footprint from material extraction and eventual recycling. It attracted a major investment from Breakthrough Energy Ventures, founded by Bill Gates, because it represents a best-in-class technology for long-term decarbonization of the electric power industry.
