OverviewMain componentsPhysical characteristicsApplicationsComparison to electric batteriesSee alsoFurther readingExternal links

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…

High-Power Energy Storage: Ultracapacitors

Ragone plot of different major energy-storage devices. Ultracapacitors (UCs), also known as supercapacitors (SCs), or electric double-layer capacitors (EDLCs), are electrical energy-storage devices that offer higher power density and efficiency, and much longer cycle-life than electrochemical batteries. Usually, their cycle-life reaches a ...

High-performance flywheels for energy storage

One motor is specially designed as a high-velocity flywheel for reliable, fast-response energy storage—a function that will become increasingly important as electric power systems become more reliant on intermittent energy sources such as solar and wind. Energy efficiency Energy storage. This research was supported in part by the MIT …

A superconducting high-speed flywheel energy storage system

Flywheel energy storage systems (FESS), coupled to an electrical motor-generator, also have been used to equalize the electrical power demand. These systems draw energy, smoothly, from the electrical system, store and return it at the demand peak. At the moment, most systems use heavy flywheels that operate at low speeds with a low …
