Scientists Found a Way to Turn Bricks Into Batteries

One of the biggest barriers to the renewable energy revolution is working out how to store power when the sun doesn’t shine and the wind doesn’t blow. Now scientists have shown standard construction bricks can be converted into energy storage units, potentially turning our houses into giant batteries.

While lithium ion battery technology has seen dramatic price drops in recent years, most experts agree that they will remain too expensive for grid-scale storage. The relative scarcity of lithium also means they’re unlikely to be able to meet all our energy needs.

That’s driven considerable research into alternative ways of storing excess renewable energy, from much cheaper molten salt batteries to approaches that use spare electricity to compress air or pump water uphill before later releasing them to drive turbines.
