Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th

A flywheel is a mechanical device that stores rotational energy in the form of kinetic energy. It primarily acts as a reservoir that absorbs and releases energy to maintain a steady speed in a rotating machine. The energy is stored by accelerating a rotor to a high speed and maintaining it at that speed.
