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

Flywheel storage power system

Flywheel storage has proven to be useful in trams.During braking (such as when arriving at a station), high energy peaks are found which can not be always fed back into the power grid due to the potential danger of overloading the system.The flywheel energy storage power plants are in containers on side of the tracks and take the excess electrical energy.
