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.
