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.

Williams Hybrid Power (WHP), part of Williams Group of companies, pioneered the use of flywheel energy storage in motorsport. WHP''s electric flywheel was used in Porsche Motorsport on their 2010 911 GT3 R
Energy storage systems (ESSs) are the technologies that have driven our society to an extent where the management of the electrical network is easily feasible. The balance in supply-demand, stability, voltage and frequency lag control,
A flywheel battery stores electric energy by converting it into kinetic energy using a motor to spin a rotor. The motor also works as a generator; the kinetic energy can be converted back to
The key technologies underpinning an FESS include flywheel rotor technology, support bearing technology, integrated electric motor/generator technology, bidirectional energy converter technology, vibration control for the
