ESS - Company Profile

ESS, Inc. is a leading provider of long-duration (4+ hours) energy storage solutions, offering the Energy Warehouse (EW), a high-performing iron flow battery designed for C&I, utility, microgrid, and off-grid applications. With a remarkable capability of up to 8 continuous hours of energy delivery and a 20+ year operating life with no capacity degradation, the EW sets itself apart. Composed of earth-abundant iron, salt, and water for its electrolyte, the EW promises safety, longevity, and the lowest levelized cost of storage (LCOS) per kWh. Founded in 2011 by a team with extensive expertise in fuel cells, electrochemistry, advanced material science, and renewable energy, ESS has focused on innovation, engineering development, and validation. Backed by ARPA-E and others, the company commenced shipping turn-key battery solutions in 2016. Notably, in 2017, the world's leading chemical company, BASF, became a significant investor in ESS, aligning their efforts to deliver sustainable energy storage solutions. With its headquarters in the United States, ESS received a $27.50M Post-IPO Equity investment from Honeywell on 25 September 2023. As ESS continues to drive the transition towards a cleaner energy future, it stands as a prominent player in the Energy, Renewable Energy, and Energy Storage industries.
