The Status and Future of Flywheel Energy Storage
Indeed, the development of high strength, low-density carbon fiber composites (CFCs) in the 1970s generated renewed interest in flywheel energy storage. Based on design strengths typically used in commercial flywheels, s. max/r is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.

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 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
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.
