Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in two hours. [17] Much of the friction responsible for this energy loss results from the flywheel changing orientation due to the rotation of the earth (an effect similar to that shown by a Foucault pendulum ).

AI Customer ServiceEnergy storage in a flywheel is realized by a spinning mass in the form of kinetic energy [144,145]. The flywheel energy storage system is mainly composed of a rotor, magnetic bearing systems, a vacuum housing and an electric machine [142,145].
Their efficiency is high during energy storage and energy transfer (>90 %). The performance of flywheel energy storage systems operating in magnetic bearing and vacuum is high. Flywheel energy storage systems have a long working life if periodically maintained (>25 years).
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.
Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy. Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
However, the high cost of purchase and maintenance of solar batteries has been a major hindrance. Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a low environmental footprint.
