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.

In vehicles, a flywheel is specifically weighted to the vehicle''s crankshaft to smooth out the rough feeling and to save energy. In city buses and intercity taxis, it can have a huge impact on reducing fuel consumption.
Electric Flywheel Basics. 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].
The Porsche 918R hybrid concept sports car with a flywheel storage system was announced in the 2010 Detroit Motor show (Amiryar and Pullen, 2017). The FESS stores KE from rotation, where the stored energy E n depends on the moment of inertia ( J ) and the rotational speed ( ω ) ( De Oliveira, 2011 ).

The storage system absorbs peak loads in the grid to spin flywheels to high rotation speeds, which stores electricity in kinetic energy form. As soon as an electric car is connected to the storage facility, the Kinetic Power Booster slows down the flywheels again and releases the energy as electricity.
