Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to. . Abstract: The flywheel energy storage system is a way to meet the high-power energy storage and energy/power conversion needs. Pumped hydro has the largest deployment so far, but it is limited by geographical locations.
