Form Energy is a climate tech startup specializing in the development and manufacturing of iron-air battery technology for long-duration, grid-scale energy storage. Their innovative batteries store energy by reversibly rusting iron, offering a significantly cheaper alternative to lithium-ion batteries for storing renewable energy for up to 100 hours. This technology addresses the intermittency of wind and solar power, enabling continuous clean energy supply for utilities and large industrial consumers like data centers. The company operates a manufacturing facility in West Virginia and is deploying its first systems with major partners like Google and Xcel Energy.
