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 …

Our iron flow batteries work by circulating liquid electrolytes — made of iron, salt, and water — to charge and discharge electrons, providing up to 12 hours of storage capacity.

Most lithium-ion batteries are only designed for one cycle per day. ESS technology can be cycled continuously without limitation, as validated by extensive testing by the U.S. Department of Energy.

Let us show you how to maximize the benefits and unique characteristics of our iron-flow battery storage solutions, the Energy Base™ (EB), Energy Warehouse ® (EW), and the Energy Center™ (EC).

ESS launches Energy Base solution, offering up to 22 hours of energy storage and decoupling power capacity from energy capacity, unlocking low-cost, long-duration energy storage.

The Energy Warehouse delivers commercial and industrial scale energy storage without the challenges associated with other battery technologies. The containerized, fully-integrated design of our long …

Our batteries are designed for longevity, boasting a 25-year lifespan. They are not only safe and sustainable but also guarantee consistent power and energy output regardless of the duty cycle.
