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. The amount of time a flywheel can store energy depends on several factors, including its mass, diameter, rotational speed, and the energy storage capacity of the system it is used in. However, in general, flywheels can store energy for short periods, ranging from a few minutes to an hour. [pdf]
