The role of flywheel energy storage in decarbonised electrical power ...
The minimum speed of the flywheel is typically half its full speed, the storage energy is be given by ½ (1 2-0.5 2) I f w f 2 where I f is the rotor moment of inertia in kgm 2 and the w f maximum rotational speed in rad/s. The power level is controlled by the size of the M/G, so this is independent of the rotor.
