4 FAQs about Differences between flywheel energy storage and motor energy storage

How does a flywheel energy storage system work?

Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.

Can flywheel energy storage be combined with other energy storage technologies?

Hybrid Energy Storage Systems: Flywheel energy storage could be combined with other energy storage technologies such as batteries or pumped hydro to create hybrid energy storage systems. Hybrid systems could provide the benefits of both technologies, extending the useful length of time they can provide electricity.

What limits the energy storage capacity of a flywheel energy storage system?

Additionally, the energy storage capacity of a flywheel energy storage system is limited by the maximum rotational speed of the rotor and the maximum allowable stresses on the rotor materials.

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.
