Flywheel Energy Storage Systems | Electricity Storage Units

This flywheel, when paired to a motor/generator unit, behaves like a battery and energy can be stored for hours and dispatched on demand. The system service life is 20 years, without limits

A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors
