Flywheel Energy Storage Basics

Flywheel energy storage (FES) is a technology that stores kinetic energy through rotational motion. KE is the kinetic energy, I am the moment of inertia, and w is the angular velocity. FES can be used as a storage device in electric vehicles. FES''s high power density and fast charging capabilities make it an ideal candidate for

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 technology, has extensive

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles of use), high specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 1

Physics: energy stored in rotating masses?

In power grids, the angular momentum of large rotating generators is known as ''inertia'' and can run to 30kWh to 30MWH per turbine. Inertia has historically been a crucial part of stabilizing grids.
