A review of flywheel energy storage systems: state of the art …
Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss. Therefore, it can store energy at high efficiency over a long duration. Although it was estimated in [3] that after 2030, li-ion batteries would be more cost-competitive than any alternative for most applications.
Flywheel Energy Storage: Why It Is So Important?
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. As a result of the energy conservation principle, the flywheel''s rotational speed decreases when energy is removed from the system and increases when energy is added.
