ESS, Inc.

Energy Storage Systems (ESS, Inc.) was launched 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 validation, backed by ARPA-E and others, the company began shipping turn-key battery solutions in 2016.

The breakthrough 50kW/400kWh Iron Flow Battery (IFB) integrates a proprietary and patented all-iron electrolyte with low cost and non-toxic materials that enables us to offer one of the lowest installed cost/kWh storage systems on the market.

ESS Inc. envisions future limitations of Li-ion in the next frontier of flexible, long-duration storage and sees flow batteries, and especially the all-iron flow battery with its fast response time and limitless cycling, as being capable of making a future of energy storage capabilities a reality today.

ESS Inc. is poised to lead project developers, utility representatives, and EPC’s in the transition to a more flexible, longer-duration energy storage asset that can be used in many different use cases and for many different durations of time from 2-8 hours when responding to increased penetration of renewables. The IFB provides the flexibility to install a storage asset today that will be able to react to the emerging applications and use cases of the future.
