About the Energy Warehouse

Utilizing earth-abundant iron, salt and water for its electrolyte, and simple materials for battery components, the ESS Energy Warehouse is a durable, environmentally safe, long-duration storage solution that is ideally suited for time-shifting renewable energy, managing a facility’s demand charges, and smoothing the intermittency of renewables on a constrained grid. The EW has a lifespan that exceeds 20,000 cycles, low maintenance requirements, and an energy capacity of eight hours. It matches well with the 25-year life span of solar and wind projects, supporting those applications’ low levelized cost of energy (LCOE) requirements.
