Flywheel energy storage

OverviewMain componentsPhysical characteristicsApplicationsComparison to electric batteriesSee alsoFurther readingExternal links

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
