flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. To oppose speed fluctuations effectively, a flywheel is given a high rotational inertia ...

The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to. E = 12Iω2 [J], E = 1 2 I ω 2 [ J], (Equation 1) 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 ...
Flywheel energy storage systems (FESS) use electric energy input which is stored in the form of kinetic energy. Kinetic energy can be described as "energy of motion," in this case the motion of a spinning mass, called a rotor. The rotor spins in a nearly frictionless enclosure. When short-term backup power is required because utility power ...
In 2009, Beacon Power got its big break, receiving a $43MM Department of Energy grant to build the 20-megawatt flywheel plant in Stephentown, NY a small town with a population of just 2,903. In total, the flywheel storage plant would cost $69MM, so the $43MM DoE grant paid for the majority of the project''s costs.
The useable energy of a flywheel is therefore given by (Equation 3) E U s e a b l e = 1 2 I (ω max 2 − ω min 2) = 1 2 I ω max 2 (1 − ω min 2 ω max 2) [J]. Electrical flywheels are kept spinning at a desired state of charge, and a more useful measure of performance is standby power loss, as opposed to rundown time.

Share this post. Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.
