Technical FAQs 4

Are flywheel energy storage systems feasible?

Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.

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 the difference between a flywheel and a supercapacitor?

Comparing to batteries, both flywheel and supercapacitor have high power density and lower cost per power capacity. The drawback of supercapacitors is that it has a narrower discharge duration and significant self-discharges. Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss.

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.
