How Energy Storage Works

Compressed Air Energy Storage is a system that uses excess electricity to compress air and then store it, usually in an underground cavern. To produce electricity, the compressed air is released and used to drive a turbine. To discharge the stored energy, the motor acts as a generator, converting the stored kinetic energy back into electricity.
