Summary: Flywheel energy storage has evolved from ancient mechanical designs to cutting-edge solutions for renewable energy grids. This article explores its history, current applications, and future trends, with actionable insights for industries seeking sustainable energy . . 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. . and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently. Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact. These include: This CTW description focuses on flywheels.
