Flywheel Energy Storage System Fess

Sibley chief technology officer of kinetech power company describes his breakthrough patented flywheel energy storage system.

Flywheel energy storage system fess.

Electric energy input accelerates the mass to speed via an integrated motor generator. The flywheel energy storage system fess is a new technology for high efficiency energy storage of 5 8kwh. Most modern high speed flywheel energy storage systems fess consist of a huge rotating cylinder supported on a stator the stationary part of a rotary system by magnetically levitated bearings. Fess and the energy landscape page 3 source.

14 5 are common in many transportation uses including for busses trains cars etc. It consists of an electrical machine back to back converter dc link capacitor and a massive disk. Flywheel energy storage systems fess employ kinetic energy stored in a rotating mass with very low frictional losses. Flywheel energy storage system fess is an electromechanical energy storage system which can exchange electrical power with the electric network.

The energy is discharged by drawing down the kinetic energy using the same motor generator. Flywheel energy storage fes works by accelerating a rotor flywheel to a very high speed and maintaining the energy in the system as rotational energy. Flywheel energy storage system fess an introduction to mechanical flywheel technology for dispatchable generation in the renewable energy market russell hanna strategy product manager 1 m32 m160. The center for electromechanics has developed and is currently testing a 2 mw 130 kwh 480 mj flywheel energy storage system fess designed as a load leveling energy management device.

One energy storage technology now arousing great interest is the flywheel energy storage systems fess since this technology can offer many advantages as an energy storage solution over the. Flywheel energy storage is a promising technology for replacing conventional lead acid batteries as energy storage systems. The fess will effectively unleash the potential of renewable energy and transportation markets quickly accepting intermittent energy for later use. The stored energy is the sum of the kinetic energy of the individual mass elements make up the flywheel.

The flywheel energy storage system consists of the energy storage flywheel a high speed induction motor generator and a bi directional power converter. Flywheel energy storage systems see fig.
