Does the flywheel energy storage store electrical energy or mechanical energy
A flywheel battery is a mechanical energy storage system that operates by spinning a mass, known as a rotor, at a very high speed. When excess electricity is available, it is used to accelerate a flywheel to a very high speed. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel. . 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. The core technology is the rotor material, support bearing, and electromechanical control system.
