With construction starting this year, Form Energy hopes its West Virginia factory will start producing its first batteries as early as 2024. Form Energy also says these iron-air batteries will form “power blocks” where iron-air batteries handle long load times, while lithium-ion batteries take care of spikes in demand. The downsides to iron-air batteries? They’re big and also slow to recharge, which is likely why lithium-ion will remain the battery of choice for electric cars and smartphones. ![]() Lithium-ion only provides approximately four hours of storage, whereas iron-air could deliver up to 100 hours-a full four days to bridge those energy gaps. Right now, these batteries’ primary task would be to bridge the gap when utilities need more power during peak hours, and as green energy eats up a bigger share of the energy pie, they could also crucially store excess energy on sunny days to shore up supply when the clouds roll in. Secondly, and most importantly, iron-air batteries would be 10 times cheaper, perform better, and last 17 times longer. This tech’s adoption could help curtail the large amounts of water used to mine lithium (not to mention alleviating the potential for groundwater contamination). As their name suggests, these batteries use primarily iron, the fourth most abundant element on Earth, and. For one, iron-air batteries solve a few of lithium’s biggest shortcomings right off the bat. NASA first started experimenting with iron-air batteries back in the late 1960s, and it’s obvious why this next-gen storage system has engineers excited. To charge it back up, a current reverses the oxidation and turns the cells back into iron. Using a principle called “reverse rusting,” the cells “breathe” in air, which transforms the iron into iron oxide (aka rust) and produces energy. And the company is willing to put $760 million behind the idea by building a new manufacturing facility in West Virginia.Įach iron-air battery is about the size of a washer/dryer set and holds 50 iron-air cells, which are then surrounded by an electrolyte (similar to the Duracell in your TV remote). Now, Form Energy, a Massachusetts-based energy company, thinks it has the solution: iron-air batteries. Lithium-ion batteries are only great at expending energy over a short period, the compound lithium isn’t exactly readily available, and if you’ve ever seen a Tesla engulfed in flames, you know they can explode. ![]() In fact, lithium is so vital to humanity’s green energy future that people are trying to figure out how to get more of it as soon as humanly possible.īut what might work for your laptop isn’t the best storage idea for power grids where energy output is measured in megawatts. It’s why you’ll find them in consumer products from electric cars, smartphones, and everything in between. If you want to store energy, lithium-ion batteries are really the only game in town.
