How Energy Storage Works

Flywheel Energy Storage Systems convert electricity into rotational kinetic energy stored in a spinning mass. The flywheel is enclosed in a cylinder and contains a large rotor inside a vacuum to reduce drag. Electricity drives a motor that accelerates the rotor to very high speeds (up to 60,000 rpm). To discharge the stored energy, the motor
