Flywheel Energy Storage System (FESS) | Energy Storage …
Flywheel energy storage systems (FESS) are increasingly important to high power, relatively low energy applications. They are especially attractive for applications requiring frequent cycling given that they incur limited life reduction if used extensively (i.e., they can undergo many partial and full charge-discharge cycles with trivial wear per cycle).
