Its main product line centers on this iron-air technology, sold to electric utilities across the United States as a way to keep the grid reliable. The company is headquartered in Somerville, Massachusetts, and was founded in 2017 by Mateo Jaramillo, a former Tesla battery executive, together with MIT battery scientist Yet-Ming Chiang and other co-founders.
Form Energy manufactures its batteries at Form Factory 1, a 550,000-square-foot plant built on the former Weirton Steel mill site in West Virginia, employing close to 400 people. In 2026 Google signed a battery supply agreement with the company to help power a data center in Minnesota.
