Fuel cells are devices that produce electricity by converting chemical energy directly into electrical energy. Unlike batteries, which store electricity and eventually run out, fuel cells can keep ...

What if the future of aviation didn’t rely on heavy lithium-ion batteries or complex hydrogen systems, but instead on a fuel as simple and abundant as sodium? At MIT, researchers are turning this bold ...

Whether it’s to keep the lights on after a natural disaster or just to avoid peak energy rates, more people than ever are adding battery energy storage to their home solar systems — but li-ion ...

Fuel cells powered with the metal could provide a new source of electric power that's far more energy-dense than lithium-ion batteries. A new type of fuel cell that runs on sodium metal could one day ...
