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.

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.

Electrical energy is generated by rotating the flywheel around its own shaft, to which the motor-generator is connected. The design arrangements of such systems depend mainly on the shape and type

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].
