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. . 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. . A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes. . TransportationAutomotiveIn the 1950s, flywheel-powered buses, known as . • • • – Form of power supply• – High-capacity electrochemical capacitor . GeneralCompared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no. . Flywheels are not as adversely affected by temperature changes, can operate at a much wider temperature range, and are not subject to many of the common failures of chemical . They are also less potentially damaging to the environment, being largely made of . • Beacon Power Applies for DOE Grants to Fund up to 50% of Two 20 MW Energy Storage Plants, Sep. 1, 2009• Sheahen,.
