Are flywheel energy storage systems suitable for commercial applications?

Among the different mechanical energy storage systems, the flywheel energy storage system (FESS) is considered suitable for commercial applications. An FESS, shown in Figure 1, is a spinning mass, composite or steel, secured within a vessel with very low ambient pressure.

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.

What is the difference between a flywheel and a battery storage system?

Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.

What are the potential applications of flywheel technology?

Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

How does a Flywheel energy storage system work?

A flywheel energy storage system works by applying a torque in the direction of rotation to speed up the rotor, and applying a torque in the reverse direction to slow it down. On one level, it is simple to implement and understand in comparison with many other energy storage methods, and can store and release energy for potentially unlimited cycles.

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.
