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.

By introducing energy storage, even with only a low-voltage distribution grid at hand, high charge-power can be provided while at the same time stabilizing the grid. Superior cycle life of the flywheel energy storage, the ability to feed power back into the grid as well as easy transportability are further advantages of FESS for EV fast charging.
A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
