Superconducting magnetic energy storage (SMES) systems use superconducting coils to efficiently store energy in a magnetic field generated by a DC current traveling through the coils. Due to the electrical resistance of a typical cable, heat energy is lost when electric current is transmitted, but this problem does not exist in an SMES system.
Over a medium of huge magnetic fields, the integral can be limited without causing a significant error. When the coil is in its superconducting state, no resistance is observed which allow to create a short circuit at its terminals. Thus, the indefinitely storage of the magnetic energy is possible as no decay of the current takes place.
