Learn how flywheel energy storage works | Planète Énergies
The technology is referred to as a flywheel energy storage system (FESS). The amount of energy stored is proportional to the mass of the rotor, the square of its rotational speed and the square of its radius. Flywheel energy storage consists in storing kinetic energy via the rotation of a heavy object. Find out how it works.

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.
