But what might work for your laptop isn’t the best storage idea for power grids where energy output is measured in megawatts. Lithium-ion batteries are only great at expending energy over a short period, the compound lithium isn’t exactly readily available.

Lithium-ion only provides approximately four hours of storage, whereas iron-air could deliver up to 100 hours

Form Energy, a Massachusetts-based energy company, thinks it has the solution: iron-air batteries. And the company is willing to put $760 million behind the idea by building a new manufacturing facility in West Virginia.

Very interesting.

Sodium Ion batteries are what Tesla is switching to.
