Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. 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. . 6W monitors the market across 60+ countries Globally, publishing an annual market outlook report that analyses trends, key drivers, Size, Volume, Revenue, opportunities, and market segments. This. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage.
