The Status and Future of Flywheel Energy Storage
The useable energy of a flywheel is therefore given by (Equation 3) E U s e a b l e = 1 2 I (ω max 2 − ω min 2) = 1 2 I ω max 2 (1 − ω min 2 ω max 2) [J]. Electrical flywheels are kept spinning at a desired state of charge, and a more useful measure of performance is standby power loss, as opposed to rundown time.
