A FESS is an electromechanical system that stores energy in form of kinetic energy. A mass rotates on two magnetic bearings in order to decrease friction at high speed, coupled with an electric machine. The entire structure is placed in a vacuum to reduce wind shear [118], [97], [47], [119], [234].
Flywheels are only viable for utility-scale energy storage when multiple units can be integrated into an array to achieve the necessary storage capacity. Developing hardware, software and a test platform is necessary to successfully demonstrate multi-unit array operation with balanced power and state of charge (SoC).

Energy storage in flywheels. A flywheel stores energy in a rotating mass. Depending on the inertia and speed of the rotating mass, a given amount of kinetic energy is stored as rotational energy. The flywheel is placed inside a vacuum containment to eliminate friction-loss from the air and suspended by bearings for a stabile operation.
