First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
These unique properties give flywheel systems many advantages over other competing energy storage systems, particularly regarding performance, adaptability and longevity.
Due to their simple design and frictionless characteristics, flywheel systems can reach very high efficiencies of 70-95%, where only a small fraction of the energy is lost during storage.
