Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
The superconducting coil, the heart of the SMES system, stores energy in the magnetic fieldgenerated by a circulating current (EPRI, 2002). The maximum stored energy is determined by two factors: a) the size and geometry of the coil, which determines the inductance of the coil.
Keywords: SMES, storage devices, large-scale superconductivity, magnet. Superconducting magnet with shorted input terminals stores energy in the magnetic flux density (B) created by the flow of persistent direct current: the current remains constant due to the absence of resistance in the superconductor.
Here the energy is stored by disconnecting the coil from the larger system and then using electromagnetic induction from the magnet to induce a current in the superconducting coil. This coil then preserves the current until the coil is reconnected to the larger system, after which the coil partly or fully discharges.
This higher critical current will raise the energy storage quadratically, which may make SMES and other industrial applications of superconductors cost-effective. The energy content of current SMES systems is usually quite small.
As energy production shifts more and more to renewables, energy storage is increasingly more important. A high-T c superconductor would allow for efficient storage (and transport) of power. Batteries are also much easier to keep refrigerated if necessary, and there are greater efficiency gains to be had.
