A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. Flywheels have been around for thousands of years. The earliest application is likely the potter's wheel. Perhaps the most common application in more. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. For discharging, the motor acts as a generator, braking the rotor to. . ful project. Batteries also started out as small fry, so we should not write off flywheels any time soon.
