Form Energy, a startup developing energy storage solutions, said on Thursday that it had developed an iron-air battery chemistry that could help incorporate more renewable energy into the power grid. Form Energy unveiled today its first commercial product. It is a rechargeable iron-air battery capable of delivering electricity for 100 hours at system costs competitive with conventional power plants and at less than one-tenth the cost of the lithium-ion battery chemistry, the company said. The basic metal for its design – iron – is one of the safest, cheapest, and most abundant minerals on Earth. Form Energy’s front-of-the-meter iron-air battery can be used continuously over a multi-day period and is expected to enable a reliable, secure, and fully renewable electric grid year-round, the Boston-based startup says. “We conducted a broad review of available technologies and have reinvented the iron-air battery to optimize it for multi-day energy storage for the […]
