Vacuum for Energy Storage

Vacuum ensures efficiency. To ensure the efficiency of a flywheel as an energy storage device, the constant losses through friction have to be reduced to a minimum. To do so, the flywheel housing is evacuated with vacuum pumps. Typical targeted pressures are 1·10-1 hPa down to 1·10-3 hPa or even less. As a result, both …

Flywheel

A flywheel is a mechanical device which stores energy in the form of rotational momentum. Torque can be applied to a flywheel to cause it to spin, increasing its rotational momentum. This stored momentum can then be used to apply torque to any rotating object, most commonly machinery or motor vehicles. In the case of motor vehicles and other ...

Flywheel energy storage

A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.

Domestic flywheel energy storage: how close are we?

A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That''s 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for about 10 minutes. I think you might be over-estimating how much energy these things can store. – Tim.
