Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 1.

FESSs have many advantages compared with other energy storage units. These include high energy efficiency, rapid response times, a large amount of instantaneous power, low maintenance costs, a long service life, and environmental benefits [19, 20]. However, FESSs have some disadvantages, mainly in terms of their low instantaneous power output.
