Technical FAQs 4

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.

Are flywheels and supercapacitors a good alternative to battery storage?

When it comes to energy storage solutions, it's essential to find one that is efficient, reliable, safe, and environmentally friendly. Luckily, two new technologies - flywheels and supercapacitors - offer a promising alternative to traditional battery storage. But which one is better?

Are flywheels and supercapacitors safe to use?

Both flywheels and supercapacitors are safe to use. Flywheels are built to contain the rotor in the rare event of a failure, and supercapacitors do not contain any toxic chemicals. As you can see, both flywheels and supercapacitors have their pros and cons. Flywheels have a higher energy density, and supercapacitors have higher power density.

What is a flywheel energy storage system?

Flywheel Flywheel energy storage systems (FESSs) are formidable solutions in energy storage, boasting a range of advantages that position them as a competitive alternative. Among these advantages are the notably high energy density, low maintenance requirements, and rapid response capabilities inherent to FESS technology.
