Energy storage systems: a review
Schematic diagram of superconducting magnetic energy storage (SMES) system. It stores energy in the form of a magnetic field generated by the flow of direct current (DC) through a superconducting coil which is cryogenically cooled. The stored energy is released back to the network by discharging the coil. Table 46.
