Flywheel Energy Storage

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

How Does Flywheel Work ? – Its Function & Working Principle

The energy stored to these flywheel are proportional to their square of rotating speed. A torque is applied to the flywheel to store rotational energy and when needed; energy is released from flywheel in the form of torque applied on the mechanical load. Thus it increase its rotational speed while storing energy and loose while releasing it.
