The article discusses the possibilities of energy storage in the superconducting winding. Milestones of superconducting magnetic energy storage technologies were presented and the evolution of devices designed in the world was described. This article presents the possible configurations of the high-temperature superconducting winding with particular emphasis on the solenoid and toroidal configuration and the principle of operation of the device. As an example of the device, the design and research results of the Polish superconducting magnetic energy storage physical model with energy 34 kJ at 13 K was discussed. The possibility of controlling the energy value and magnetic field distribution using the geometrical parameters of the windings in solenoidal and toroidal configurations was discussed. Studies of the Polish design of the superconducting magnetic energy storage model have shown that energy stored in the superconducting magnetic energy storage winding can be increased. By choosing the appropriate winding configuration with magnetic shielding, a strong magnetic field outside the device can be limited to the values allowed by the standards. Finally, the possible uses of the superconducting magnetic energy storage in the power grid are listed.
