Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. How does a flywheel energy storage system work?. A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to. . Energy storage systems (ESSs) can alleviate the problems associated with renewable energy power generation technology. Electrical energy is thus converted to kinetic energy for storage. A rotating mass, ideally spinning in a vacuum. High-speed flywheels- made from composite materials like carbon fiber and fiberglas, typically operate at speeds between 20,000 and 60,000 revolutions per minute (RPM) and can. .
