6 FAQs about [Current status of superconducting energy storage]
What is superconducting magnetic energy storage (SMES)?
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.
What is a superconducting substation?
The substation, which integrates a superconducting magnetic energy storage device, a superconducting fault current limiter, a superconducting transformer and an AC superconducting transmission cable, can enhance the stability and reliability of the grid, improve the power quality and decrease the system losses (Xiao et al., 2012).
How does critical current affect energy storage in a SMES system?
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.
How to design a superconducting system?
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.
Can a superconductor reduce the cost of a refrigeration process?
If the cost of the refrigeration process is eliminated by using a room temperature (or near room temperature) superconductor material, other technical challenges toward SMES must be taken into consideration. A superconducting magnet enable to store a great amount of energy which can be liberated in a short duration.
How does a superconducting coil store energy?
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.
