Practical Flywheel Energy Storage

The capacity of a flywheel is the total energy stored – the rating is the rate at which energy may be extracted. A 1600kWhr capacity unit may have a rating of 25000kW for 200 seconds. A spinning flywheel therefore can be regarded as a heavy duty storage battery – the only limitation on rating being the capability of the power transfer means.

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.

Flywheel Energy Storage
