Flywheel energy storage
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. The energy is converted back by slowing down the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy …
Design and analysis of a flywheel energy storage system fed by …
Therefore, increasing the angular velocity of the flywheel is more effective than increasing the mass of the flywheel. Flywheels are generally used as a storage device in the flywheel energy storage system (FESS)s which have long life-span, high power density, high efficiency, low maintenance cost etc. [ 12 ].
Flywheel Energy Storage
ω is the angular velocity of the flywheel. Thus the best flywheel in terms of moment of inertia could be one which is larger, spoked and lightweight, but with a heavy rim of metal. If the rim is twice as heavy as the original, this would store double the energy that a lighter rim would, but the mechanical limitations increase correspondingly.
Flywheel energy storage
This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.
