Flywheel Energy Storage

A flywheel is a simple form of mechanical (kinetic) energy storage. Energy is stored by causing a disk or rotor to spin on its axis. Stored energy is proportional to the flywheel''s mass (more accurately, its mass moment of inertia) and the square of its rota- tional speed.

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

A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.
