Energy storage is the capture of produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an or . Energy comes in multiple forms including radiation, , , , electricity, elevated temperature, and . En.

Superconducting magnetic energy storage (SMES) systems in the created by the flow of in a coil that has been cooled to a temperature below its . This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970. A typical SMES system includes three parts: superconducting , power conditioning system a.

In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh.

In , operates in a flywheel storage power plant with 200 flywheels of 25 kWh capacity and 100 kW of power. Ganged together this gives 5 MWh capacity and 20 MW of power. The units operate at a peak speed at 15,000 rpm. The rotor flywheel consists of wound fibers which are filled with resin. The installation is intended primarily for frequency c.

Flywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of the flywheel. W.
