The project marks the first commercial deployment of Form Energy’s iron-air battery technology. The below press release from Great River Energy shares more details about the project and partnership.
Iron is also one of the most abundant elements on Earth, which the company says helps make this technology affordable and scalable. In collaboration with Great River Energy, the company broke ground on its first commercial battery installation in Cambridge, Minnesota in August.
To ensure grid reliability and affordability regardless of weather events, grid outages, or other periods of prolonged stress – while meeting rising energy demand – we need new technologies capable of storing energy for multiple days.
Of note, the recent funding round was led by a strategic investment from steelmaker ArcelorMittal, one of the largest iron-ore suppliers in the world. Significant technical and commercial challenges remain before the company can deliver on the promise of affordable, long-duration energy storage based on iron.
The Form Energy multi-day energy storage solution is designed to store energy for up to 100 hours, far surpassing the capabilities of traditional lithium-ion batteries.
Li-ion batteries continue to be an effective energy storage solution for renewable projects, but these batteries can only deliver their rated power for up to four hours before becoming cost-prohibitive.
