Technical FAQs 4

What is a flywheel energy storage system?

Energy storage systems (ESSs) play a very important role in recent years. Flywheel is one of the oldest storage energy devices and it has several benefits. Flywheel Energy Storage System (FESS) can be applied from very small micro-satellites to huge power networks.

What are the application areas of flywheel technology?

Application areas of flywheel technology will be discussed in this review paper in fields such as electric vehicles, storage systems for solar and wind generation as well as in uninterrupted power supply systems. Keywords - Energy storage systems, Flywheel, Mechanical batteries, Renewable energy. 1. Introduction

How do flywheels store kinetic energy?

Beyond pumped hydroelectric storage, flywheels represent one of the most established technologies for mechanical energy storage based on rotational kinetic energy . Fundamentally, flywheels store kinetic energy in a rotating mass known as a rotor [, , , ], characterized by high conversion power and rapid discharge rates .

How much energy is stored in a composite flywheel?

Typical energies stored in a single unit range from less than a kilowatt-hour to levels approaching 150 kilowatt-hours. Thus, a single composite flywheel can be equivalent, in stored energy, from one to more than 100 automotive batteries. Moreover, in flywheel systems, the stored energy and output power are relatively independent of each other.
