Form Energy makes iron-air batteries that can deliver power to the grid for up to 100 hours.[1] The chemistry relies on iron instead of lithium, cobalt and nickel: the battery turns iron into rust when it discharges and back into iron when it charges.[1] It manufactures batteries at Form Factory 1, a one-million-square-foot plant in Weirton, West Virginia.[2] Proceeds will fund manufacturing scale-up in Weirton and commercial deployments.[3] Google is building a Minnesota data center that will be partly powered by a 30-gigawatt-hour Form battery that cost it about $1 billion, TechCrunch reported.[1] The Wall Street Journal reported a backlog of commercial projects worth about 80 gigawatt-hours of storage.[1]
Crusoe said in March 2026 that it would buy 12 gigawatt-hours of Form batteries, and Xcel Energy and FuturEnergy Ireland are also customers.[1]
