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.
One motor is specially designed as a high-velocity flywheel for reliable, fast-response energy storage—a function that will become increasingly important as electric power systems become more reliant on intermittent energy sources such as solar and wind. As the world looks to limit greenhouse gas emissions, carbon-free renewable energy ...
