Posted on Posted On Categories Posted In Latest News

ESS Inc. is operating a customized All-Iron Flow Battery (IFB) system at Stone Edge Farm winery in Sonoma, California to demonstrate how energy storage can enable net zero, with intermittent renewables, in an advanced microgrid application. The iron, salt, and water electrolyte was hydrated on-site as part of a two day installation and commissioning. The 60 kWh IFB system provides multiple services that will maximize the microgrid’s use of renewables.
