Flywheel energy and power storage systems
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.

Flywheel Energy Storage | Working & Applications | Electricalvoice
A flywheel energy storage can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. They work by spinning up a heavy disk or rotor to high speeds and then tapping that rotational energy to discharge high power bursts of electricity. It is difficult to use flywheels to store energy for
