At its core, a flywheel energy storage system stores energy in the form of rotational kinetic energy. The system consists of a large rotating mass, or rotor, that spins inside a vacuum-sealed container.

It is now (since 2013) possible to build a flywheel storage system that loses just 5 percent of the energy stored in it, per day (i.

A typical system consists of a flywheel supported by connected to a. The flywheel and sometimes motor–generator may be enclosed in a to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large flywheel rotating on mechanical bearings. Newer systems use composite that have a hi.
