DEVELOPMENT AND PROSPECT OF FLYWHEEL ENERGY STORAGE
Establishing Flywheel Energy Storage Requirements
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. While some systems use low mass/high spee. [PDF]
