These flywheels are made from high-strength carbon-fiber composites, designed to minimize energy loss and maximize mechanical efficiency. 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. . and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently. There is noticeable progress in FESS, especially in utility, large-scale deployment for the electrical grid, and renewable energy applications. This. . Flywheels have largely fallen off the energy storage news radar in recent years, their latter-day mechanical underpinnings eclipsed by the steady march of new and exotic battery chemistries for both mobile and stationary storage in the modern grid of the 21st century grid. One such technology is flywheel energy storage systems (FESSs).

FESS can be used in conjunction with medium and long duration mechanical/thermal/chemical storages to mitigate slow ramp up times of the latter and accelerate storage response. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) 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. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. A rotating mass, ideally spinning in a vacuum. Video 1 is a simple video that illustrates the concept of flywheel. .
