One of the most exciting companies in grid-level renewable energy storage is Form Energy. Its revolutionary iron-air technology promises to outperform lithium “high-capacity battery” projects by 10. % of cost. We are preparing to scale up with our first factory.
The foam grid-scale battery is built around giant flat iron-air cells about 1 meter (3.3 feet) square, about 50 of which are inserted into washing machine-sized modules and immersed in a liquid electrolyte. I’m here. These cells use the rust cycle to function effectively. Add energy to the iron oxide to charge it back to metallic iron, add oxygen to start the rusting process and release the energy.
Iron is cheap and plentiful, making these modules very affordable. Long lasting, safe and recyclable. By disassembling the battery, the metal can be taken out and used elsewhere. All of these factors combine to make batteries extraordinarily affordable, with a levelized cost (LCoS) of over 10 times lower than that of lithium batteries, even before taking into account the projected scarcity of lithium resources. It is a form of energy storage for a price.
Of course, they don’t charge or discharge as quickly as lithium, so they might work with lithium grid batteries in hybrid configurations. , states that it is excellent when energy needs to be stored for about 100 hours or longer.
This is the main vulnerability of any renewable grid. This is the kind of storage you need during days of severe storms that slash solar and wind power. Form’s proposal certainly generated a lot of excitement among investors. His Breakthrough Energy Ventures at Bill Gates has been around for some time, along with Luxembourg steel giant ArcelorMittal and many others. The Series E funding round brought him a staggering US$450 million, bringing the company’s total funding to more than his US$800 million.
So it’s time to go commercial. Last month, the company announced that it had selected a location for its first battery manufacturing plant in the United States. It is a 55-acre facility in Weirton, West Virginia. The US$760 million project will employ about 750 people, and construction is expected to begin later this year, with the first iron-air battery deployment “for widespread commercialization” in 2024. is scheduled to start.
