Environmental concerns are also driving research into flywheel energy storage systems (FESS). Flywheels are often large and heavy because they are able to store more energy that way. On the other hand, smaller and lighter wheels are also used in many situations because they can spin much faster and thus much more kinetic energy is generated this way.
Energy storage systems (ESSs) are the technologies that have driven our society to an extent where the management of the electrical network is easily feasible. The balance in supply-demand, stability, voltage and frequency lag …
