Flywheel Energy Storage (FES) is a type of mechanical energy storage system that uses rotational kinetic energy to store and generate electricity. This technology involves spinning a flywheel at high speeds to store energy, which can be rapidly released when needed. 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. Kinetic energy can be described as “energy of motion,” in this case the motion of a spinning mass, called a rotor. The core technology is the rotor material, support bearing, and electromechanical control system. FES systems have been gaining attention in recent years. .
