Form Energy’s iron-air battery technology has attracted interest from another US utility, Puget Sound Energy, which is considering deploying a pilot project in its service area. The new partnership could see Form Energy and Pug Sound Energy jointly develop a 10MW system with 1,000MWh capacity, equivalent to 100-hour duration. The company’s battery technology uses iron and air, which are used to replace electricity generating capacity and the economic benefit as assets retire. The first agreement for a utility pilot project with Minnesota’s Great River Energy was announced in 2020.

The system could be installed and in place by the end of 2026.
