Compressed-air energy storage

Compressed-air energy storage. A pressurized air tank used to start a diesel generator set in Paris Metro. Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. [1]
