What is flywheel energy storage?
Flywheel energy storage is a technology with great potential for rapid response and short duration, high cycle applications. It is explained and compared to lithium-ion batteries in the context of its place in the energy storage landscape.
How can flywheels be more competitive to batteries?
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
What is a Flywheel Energy Storage System (FESS)?
A Flywheel Energy Storage System (FESS) is defined as a system that stores energy for a distinct period of time to be retrieved later. There is a class distinction between flywheels used for smoothing the intermittent output of an engine or load on a machine and these energy storage systems.
How much energy is stored in a vehicle mounted flywheel system?
The energy stored in a vehicle-mounted flywheel system is typically low, being of similar magnitude to the kinetic energy of the vehicle operating at a moderate speed.
What is the most common flywheel energy storage configuration?
The most common configuration for flywheel energy storage is a hermetically sealed system incorporating a motor generator, as explained in Section 1 (Fig. 11.1).
How does a flywheel store energy?
A flywheel stores energy by rotating a mass, or rotor, about a fixed axis. The energy stored in the flywheel rises when the angular speed of the rotor is increased and reduces when it is slowed down. The maximum energy is usually limited by the maximum angular speed, itself limited by structural considerations.
