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. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of. . Flywheel energy storage stores kinetic energy by spinning a rotor at high speeds, offering rapid energy release, enhancing grid stability, supporting renewables, and reducing energy costs. What is Flywheel Energy Storage? Flywheel energy storage is a form of mechanical energy storage that works by. . Some of the key advantages of flywheel energy storage are low maintenance, long life (some flywheels are capable of well over 100,000 full depth of discharge cycles and the newest configurations are capable of even more than that, greater than 175,000 full depth of discharge cycles), and negligible. . Flywheel energy storage (FES) represents a mechanical approach to storing energy, distinct from chemical batteries or pumped hydro.
