The Status and Future of Flywheel Energy Storage

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