First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. 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. . However, only a small percentage of the energy stored in them can be accessed, given the flywheel is synchronous (Ref. FESS is used for short-time storage and typically offered with a charging/discharging duration between 20 seconds and 20 minutes. A rotating mass, ideally spinning in a vacuum. The primary types include mechanical flywheels, magnetic bearings, and composite flywheel systems, which each utilize distinct technologies to optimize energy retention. .
