It is well known, that the electrical energy storage in the large scale is basically difficult process. Such a process is marked by the energy losses, as the conversion of electrical energy into another form, is most frequently for example mechanical, and then back to the primary electrical form. Though, the superconducting magnetic energy storage (SMES) technology offers the energy storage in an unchanged form, which is advantageous primarily in the achieved efficiency. Magnetic resonance imaging (MRI) devices, commonly used in the medical facilities are based on the application of superconducting magnet. After its rejection from operation, there is possibility of using such ecological devices for energy storage purposes. The paper gives a short review of current UPS and energy storage technologies, SMES applications and short section about a research project running at the Faculty of Mining, Ecology, Process control and Geotechnologies at Technical University in Ko_ice, Slovakia, which deals with using rejected MRI for electrical energy storage and backup power supply purposes.
