Long-Duration
Energy Storage That's Safe
ESS Tech, Inc. (ESS) News
Enable resilient, reliable energy today
ESS iron flow technology is essential to meeting near-term energy needs. Demand from AI data centers alone is projected to increase 165% by 2030 and electricity grids around the world will need to deploy 8 TW of long-duration energy storage (LDES) by 2040 to meet clean energy targets. As demands on the grid continue to grow, LDES will keep the lights on.
Make renewable baseload energy possible
ESS solutions capture excess energy when it is available to provide uninterrupted power when it’s not. With up to 22 hours of energy storage, ESS’ scalable, flexible solutions enable intermittent energy to provide baseload power to meet growing energy demand from AI data centers and an increasingly electrified society.
Maximize value with flexible, cost-effective solutions
ESS’ American-made solutions are rapidly deployable, available in months instead of years. Iron flow technology delivers unlimited cycling with zero capacity degradation over a 25-year design life.
Leading the charge
ESS continues to lead the industry with a commitment to innovation, research and development that underpins every iron flow battery project. These awards underscore our commitment to powering data centers, companies and communities worldwide with clean reliable energy made possible with ESS’ iron flow technology.
