Critical Review of Flywheel Energy Storage System
A flywheel stores energy in a rotating mass, and the kinetic energy produced is stored as rotational energy. The amount of kinetic energy stored depends on the inertia and speed of the rotating mass. In order to eradicate any energy loss due to friction, the flywheel is placed inside a vacuum containment.
