Modern flywheels can achieve round-trip efficiencies of 85–90%, comparable to advanced battery systems. . Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact. This article comprehensively reviews the key components of FESSs, including flywheel rotors, motor types, bearing. . A flywheel energy storage system stores energy mechanically rather than chemically. It operates by converting electrical energy into rotational kinetic energy, where a heavy rotor (the flywheel) spins at high speed within a vacuum chamber. 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 flywheel energy storage system (FESS) offers a fast dynamic response, high power and energy densities, high efficiency, good reliability, long lifetime and low maintenance requirements, and is Galp, a Portuguese energy company, has announced plans to build a 5 MW/20 MWh battery storage system. . There is noticeable progress in FESS, especially in utility, large-scale deployment for the electrical grid, and renewable energy applications. It aligns with our core priority:. .
