NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...
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.
Vehicle braking was electric, and some of the energy was recycled back into the flywheel, thereby extending its range. Fully charged, a gyrobus could typically travel as far as 6 km (3.7 mi) on a level route at speeds of up to 50 to 60 km/h (31 to 37 mph), depending on the total weight of passengers, as top speeds varied as passenger levels ...
More precisely, a flywheel's stored energy will donate a surge in power output upon a drop in power input and will conversely absorb any excess power input (system-generated power) in the form of rotational energy. Common uses of a flywheel include smoothing a power output in reciprocating engines, flywheel energy storage, delivering energy at ...

The flywheel is an effective way of governing the Flywheel Energy Storage System (FESS) for wind power smoothing. It stores in the range of 89-93% of the mean state of charge which means that as the blades on the flywheel turn, between 89-93% of the energy is stored. [4]

In 2009 Beacon received a loan guarantee from the United States Department of Energy (DOE) for $43 million to build a 20-megawatt flywheel power plant in Stephentown, New York. [8] [9] The DOE loan for $43 million was awarded in 2010, with the plant to be online by 2011. It also was awarded $24 million from the DOE for a second flywheel plant. [10]
