This entry focuses on the design and analysis of the flywheel rotor itself. . Energy storage flywheel systems are mechanical devices that typically utilize an electrical machine (motor/generator unit) to convert electrical energy in mechanical energy and vice versa. The rotor is subject to high centripetal. . The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors, thermal storage, energy storage flywheels,[2] and others. Pumped hydro has the largest deployment so far, but it is limited by geographical locations. Moreover, the flywheel can effectively assist the hybrid drivetrain to meet the vehicle's large peak power requirements. Many storage technologies have been developed in an attempt to store the extra AC power for later use.

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. Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. 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, wind and solar power's intermittent nature prevents them from be-ing independent and reliable energy sources for micro-grids.
