Are flywheel energy storage systems feasible?

Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.

Are flywheels a viable energy solution?

Overall, the operating principles of flywheel technology underscore its potential as a robust energy solution. By mastering kinetic energy storage, efficient energy conversion processes, and effective management systems, flywheels are optimizing their role in the energy sector now and into the future.

How does a flywheel energy storage system work?

A keen example is the flywheel energy storage system integrated into the London Underground trains. The trains use flywheels to recover energy during braking, which is then deployed to power the train during acceleration. This increase in efficiency not only reduces energy costs but also contributes to lower overall emissions.

How do flywheels work?

Understanding FESS begins with recognizing their fundamental mechanisms. Unlike traditional batteries that use chemical reactions for energy storage and release, flywheels turn kinetic energy into power. Picture a spinning top; as it spins, it holds energy. When you need that energy, slowing down the spin can release it.
