The energy stored in a vehicle-mounted flywheel system is typically low, being of similar magnitude to the kinetic energy of the vehicle operating at a moderate speed.
A flywheel stores energy by rotating a mass, or rotor, about a fixed axis. The energy stored in the flywheel rises when the angular speed of the rotor is increased and reduces when it is slowed down. The maximum energy is usually limited by the maximum angular speed, itself limited by structural considerations.
Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electri-cal power system into one that is fully sustainable yet low cost.
A Flywheel Energy Storage System (FESS) is defined as a system that stores energy for a distinct period of time to be retrieved later. There is a class distinction between flywheels used for smoothing the intermittent output of an engine or load on a machine and these energy storage systems.
