The net energy ratios of the steel rotor and composite rotor flywheel energy storage systems are 2. The corresponding life cycle greenhouse gas emissions are 75. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . 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. This paper gives a review of the recent developments in FESS technologies. At the core is the rotor – a cylindrical or disc-shaped mass that spins at high speed, often in excess of tens of thousands of. .
