Abstract: The development of flywheel energy storage(FES) technology in the past fifty years was reviewed. The characters, key technology and application of FES were summarized. FES have many merits such as high power density, long cycling using life, fast response, observable energy stored and environmental friendly performance.

Domestic flywheel energy storage: how close are we?

Lets check the pros and cons on flywheel energy storage and whether those apply to domestic use ():Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance;[2] full-cycle lifetimes quoted for flywheels range from in excess of 10 5, up to 10 7, cycles of use),[5] high specific energy (100–130 W·h/kg, or

Flywheel energy storage

Here is the integral of the flywheel''s mass, and is the rotational speed (number of revolutions per second).. Specific energy. The maximal specific energy of a flywheel rotor is mainly dependent on two factors: the first being the rotor''s geometry, and the second being the properties of the material being used. For single-material, isotropic rotors this relationship can be expressed as [9]

The Status and Future of Flywheel Energy Storage

The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to (Equation 1) E = 1 2 I ω 2 [J], where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2], and ω is the angular speed [rad/s]. In order to facilitate storage and extraction of electrical energy, the rotor must be part of
