Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently. . A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to. . Flywheel energy storage is an exciting solution for efficient and sustainable energy management. Pumped hydro has the largest deployment so far, but it is limited by geographical locations.

A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. They offer rapid response times for load balancing, 3. High cycle durability enhances lifespan, 4. This energy is accumulated by accelerating the flywheel to a high speed using an electric motor.
