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 will begin demonstrating their turn-key battery solutions in a real world environment.

The breakthrough 50kW/400kWh Iron Flow Battery (IFB) will be sent to the Group NIRE facility where DNV-GL will perform third party testing on the IFB as it shifts wind power daily. The 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.
