In this storage scheme, kinetic energy is stored by spinning a disk or rotor about its axis. Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia. Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity .
