Flywheel energy storage systems (FESS) are devices that are used in short duration grid-scale energy storage applications such as frequency regulation and fault protection. The energy storage component of the FESS is a flywheel rotor, which can store mechanical energy as the inertia of a rotating disk. This article explores the …

From ( 6) we can see that the energy density of the flywheel rotor of constant thickness is determined by rotational speed ω, outer radius R, and inner radius r. For the flywheel with constant thickness rotor, we can get the stored energy density e = 5854 J/kg for the flywheel with the parameters given in Table 1.
