Shape optimization of energy storage flywheel rotor

Flywheel is a rotating mechanical device used to store kinetic energy. It usually has a significant rotating inertia, and thus resists a sudden change in the rotational speed (Bitterly 1998; Bolund et al. 2007).With the increasing problem in environment and energy, flywheel energy storage, as a special type of mechanical energy storage …

Flywheel energy and power storage systems

Eq. (1) shows that the most efficient way to increase the stored energy is to speed up the flywheel. The speed limit is set by the stress developed within the wheel due to inertial loads, called tensile strength σ.Lighter materials develop lower inertial loads at a given speed therefore composite materials, with low density and high tensile strength, is …

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.
