Imagine a giant, supercharged spinning top that stores electricity like a battery— that's flywheel energy storage in a nutshell. This 21st-century "mechanical battery" uses rotational kinetic energy to store electricity, offering 90% efficiency and 20+ year lifespans [1] [8]. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. This innovative approach harnesses kinetic energy to create a robust storage solution that addresses some major challenges faced by. . One such technology is flywheel energy storage systems (FESSs).

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.OverviewFlywheel 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 a. . A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. . Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles.
