FAQS about What percentage of energy does a steel flywheel store
How does a flywheel store energy?
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.
