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.
Superconducting batteries are the real energy gain from high-T c superconductors. There are, however, limits to this approach. A back of the envelope calculation reveals that this approach may not completely revolutionize the energy economy.
Thus, the number of publications focusing on this topic keeps increasing with the rise of projects and funding. Superconductor materials are being envisaged for Superconducting Magnetic Energy Storage (SMES). It is among the most important energy storage systems particularly used in applications allowing to give stability to the electrical grids.
This system is among the most important technology that can store energy through the flowing a current in a superconducting coil without resistive losses. The energy is then stored in act direct current (DC) electricity form which is a source of a DC magnetic field.
Some application scenarios such as superconducting electric power cables and superconducting maglev trains for big cities, superconducting power station connected to renewable energy network, and liquid hydrogen or LNG cooled electric power generation/transmission/storage system at ports or power plants may achieve commercialization in the future.
The first step is to design a system so that the volume density of stored energy is maximum. A configuration for which the magnetic field inside the system is at all points as close as possible to its maximum value is then required. This value will be determined by the currents circulating in the superconducting materials.
