kinetic energy through the principle of the conservation of energy. Older flywheel technologies were developed with steel laminate disks whereas newer systems are being developed from high-strength carbon fibre composites suspended by magnetic bearings. Flywheel trams exist in two primary forms: hybrid and zero-emissions.
A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
