flywheel energy storage a new way to save electricity

Flywheel Energy Storage Explained

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.

DIY Flywheel Energy Storage on a small scale? : r/AskEngineers

Generator flywheel and diesel were on one axis with a coupling towards the diesel. The flywheel was constructed as an engine around that axis, so the stator is the axis at 1500 rpm and the flywheel turns around at max. 4400 rpm. If energy needs to be provided, the outer rotor is slowed down by a brake in that axis, so the energy is transferred.
