Flywheel energy storage systems have a long working life if periodically maintained (>25 years). 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. . How long do flywheels last? of cycles,significantly outperforming batteries in terms of longevity. The longer it spins, the more energy it holds, similar to how the skater retains rotational energy as they keep spinning.
