When the sun isn’t shining and the wind isn’t blowing, the grid still needs a source of power. Lithium-ion batteries—like the giant batteries that Tesla has installed in Australia—can store the energy generated by renewables, but are too expensive for long-term storage.

To move completely away from fossil fuels, the grid needs a different solution. Form Energy, one startup working in that space, thinks that iron—which is cheap and abundant—is the key to building better batteries. The company’s “iron-air” batteries, which cost less than a tenth of lithium-ion batteries, can affordably store energy for days.
