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. Pumped hydro has the largest deployment so far, but it is limited by geographical locations. This technology is gaining traction for its durability, rapid response times, and eco-friendly profile. This chapter mainly introduces the main structure of the flywheel energy storage. .
