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]. is the angular speed [rad/s].
Flywheel energy storage
A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.
