Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
Flywheels can be expected to last upwards of 20 years and cycle more than 20,000 times, which is high in comparison to lead-acid (2,000 cycles), lithium-ion (<10,000 cycles) and sodium-sulfur batteries (2,500-6,000 cycles). Another advantage is the flywheel energy storage system's ability to provide energy with little start up or transition time.
