EnerVault

Founded in July 2008 by co-founders Craig R Horne and Thomas E Colson, EnerVault is a Sunnyvale, California-based clean technology company that develops large-scale iron-chromium redox flow battery systems. Featuring executive leadership from recognized industry figures including Jim Pape and Ronald J Mosso, the enterprise focuses on bridging critical gaps in long-duration power management across the grid. Operating with a dedicated workforce of 27 employees, the growing firm stores electricity safely at the megawatt-hour scale for commercial, renewable, and utility-scale energy storage applications. The organization primarily targets major utilities, renewable energy facility operators, and large power network customers requiring highly reliable and cost-effective grid stabilization solutions. Following the completed field demonstration of its initial megawatt-hour scale prototype, the business recently sought new ownership and external funding to further commercialize its proprietary redox flow battery technology.
