Maximum efficiency of flywheel energy storage

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 3to 13. The energy efficiency (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 kWh to 133 kWh.
