Flywheel Energy Storage

Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia. Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity [17]. In the present scenario, flywheels of 1 kW power storage capacity for 3 h and 100 kW for 30 s have been successfully developed. Design

This means the kinetic energy storage only increases linearly with the amount of material. On the other hand running your flywheel faster increases kinetic energy storage for free (as long as you don''t reach the stress limit). This means to keep cost low you always run your flywheel at maximum speed (for its radius). Then you either increase
