World's first grid-scale iron-chromium redox flow battery installed in California

The California Energy Commission (CEC) and the U.S. Department of Energy (DOE) have dedicated a long-duration, 250 kW iron-chromium redox flow battery in Turlock in California's Central Valley. The battery will support a solar photovoltaic (PV) plant with dual-axis tracking at an almond orchard. This is the first energy storage system using this technology to be deployed at the grid scale. EnerVault Corp. (Sunnyvale, California, U.S.) designed and manufactured the battery system, supported by a combination of private funding and research and development (R&D) grants from DOE and CEC. “The EnerVault Turlock system demonstrates the viability of iron-chromium redox flow batteries at the grid-scale,” said DOE Energy Storage Program Manager Imre Gyuk. “Long-duration energy storage, like EnerVault's is the lynchpin to grid stability as we achieve high penetration of renewable en...
