A FESS is an electromechanical system that stores energy in form of kinetic energy. A mass rotates on two magnetic bearings in order to decrease friction at high speed, coupled with an electric machine. The entire structure is placed in a vacuum to reduce wind shear [118], [97], [47], [119], [234].

Furthermore, energy storage devices are also required to achieve peak-shaving of the electrical grid and energy management flexibility of distributed storage (Wei et al., 2021).

Superconducting magnetic energy storage (SMES) devices can store "magnetic energy" in a superconducting magnet, and release the stored energy when required. Compared to other commercial energy storage systems like electrochemical batteries, SMES is normally highlighted for its fast response speed, high power density

Moreover, the term "permanent magnet" is very misleading; they are not permanent at all. Permanent magnets are made by magnetizing ferromagnetic material, a process that normally requires a substantial energy input. It is true that their magnetized state is a method for storing potential energy. This energy can be converted into, for example
