Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. 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 system correspondingly results in an increase in the speed of th…

This paper covers the types of technologies and systems employed within FESS, the range of materials used in the production of FESS, and the reasons for the use of these materials. Furthermore, this paper provides an overview …
Active power Inc. [78] has developed a series of fly-wheels capable of 2.8 kWh and 675 kW for UPS applications. The flywheel weighs 4976 kg and operates at 7700 RPM. Calnetix/Vycons''s VDC [79] is another example of FESS designed for UPS applications. The VDC''s max power and max energies are 450 kW and 1.7 kWh.
Mechanical energy storage systems take advantage of kinetic or gravitational forces to store inputted energy. While the physics of mechanical systems are often quite simple (e.g. spin a flywheel or lift weights up a hill), the technologies that enable the efficient and effective use of these forces are particularly advanced.
