Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. Energy storage is a vital component of any power system, as the stored energy can be used to offset inconsistencies in the power delivery system.
A flywheel can store energy thanks to the conservation of angular momentum. After the massive rotating element starts spinning and reaches its final velocity, in the absence of friction, it would spin indefinitely, even resisting changes in orientation and other external factors.
