The installation is intended primarily for frequency control. This service is sold to the New York power grid. [6] Stadtwerke München (SWM, Munich, Germany) uses a flywheel storage power system to stabilize the power grid, as well as control energy and to compensate for deviations from renewable energy sources. The plant originates from the ...
NASA G2 flywheel. 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 the speed of the ...
Active Power Inc. designs, manufactures, sells, and services flywheel-based uninterruptible power supply (UPS) products that use kinetic energy to provide short-term power as an alternative to conventional battery-based UPS products. The company also designs and manufactures modular devices that integrate critical power components into a pre ...
Dual-mass flywheel section. A dual-mass flywheel (DMF or DMFW) is a rotating mechanical device that is used to provide continuous energy (rotational energy) in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted vibration.
As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity (angular, or otherwise) of the system. More precisely, a flywheel's stored energy will donate a surge in power output ...

Most forms of uninterruptible power supply (UPS) can be either powered by battery or flywheel energy. These are ready for immediate use at the instant that the mains electricity fails, but the relatively small and finite amount of stored energy they contain makes them suitable for short periods of use, typically in the order of a few dozen minutes to a couple of hours depending on the actual load.
Kinetic Traction Systems' main product uses flywheel energy storage technology developed by Pentadyne Power Corp; staff from Pentadyne joined Kinetic. [2] The 36000 RPM flywheels are originally based on uranium centrifuge technology developed by Urenco [3]
