Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
With this FESS, 66% of the brake energy can be stored and reused in the best conditions. In vehicles, a flywheel is specifically weighted to the vehicle’s crankshaft to smooth out the rough feeling and to save energy. In city buses and intercity taxis, it can have a huge impact on reducing fuel consumption.
According to these equations, kinetic energy is proportional to radius with the power of 4, angle velocity with the power of two, thickness and density with the power of one, and, therefore, increasing the radius of the flywheel is the most important parameter to increase kinetic energy. However, each of these parameters has different limitations.
Flywheels as storage devices were studied in NASA research for the first time but the mechanical limitations did not justify their use in comparison to other storage devices. With the advent of anisotropic material, various advances were made to increase the efficiency of FESSs against other technologies.
In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California. The system was part of a wind power/flywheel demonstration project being carried out for the California Energy Commission.

Energy storage is not a new technology. The earliest gravity-based pumped storage system was developed in Switzerland in 1907 and has since been widely applied globally. However, from an industry perspective, energy storage is still in its early stages of development. With the large-scale generation of RE, energy storage technologies have become increasingly …

Flywheels rank among the earliest mechanical energy storage mechanisms discovered by mankind. The principle was probably first applied in the potter''s wheel, a device used to produce symmetrical ceramic containers. The millstone, a contrivance used to grind grain into flour, is another form of flywheel.
Energy storage systems (ESS) provide a means for improving the efficiency of electrical systems when there are imbalances between supply and demand.
Flywheel energy storage (FES) works by accelerating a rotor 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 …
