This Compressed Air Grid 'Battery' Is An Energy Storage Game Changer

Pumped hydropower is great. This method might be even better. Two new compressed air storage plants will soon rival the world's largest non-hydroelectric facilities and hold up to 10 gigawatt hours of energy. But what is advanced compressed air energy storage (A-CAES), exactly, and why is the method about to have a moment? Compressed air is part of a growingly familiar kind of energy storage: grid-stabilizing batteries. Like Elon Musk's battery farm in Australia and other energy overflow storage facilities, the goal of a compressed air facility is to take extra energy from times of surplus and feed it back into the grid during peak usage.
