Miniaturization of flywheel energy storage

This paper presents a small-sized flywheel energy storage system that uses a high-temperature superconductor (HTS) bearing characterized by a non-contacting bearing with no active control. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. 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. . 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. Electrical energy is thus converted to kinetic energy for storage.
