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…

Electric Flywheel Basics. The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to. E = 1 2 I ω 2 [ J], (Equation 1) where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2 ], and ω is the angular speed [rad/s].
