Hybrid gravity–flywheel systems offer a rare combination of both: slow, steady energy release using gravity — and millisecond-level power bursts using flywheels. This article explores the science, the prototypes, the potential, and the path forward for a technology that may redefine global storage. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. One advantage of gravity energy. .
