6 Frequently Asked Questions about “Energy storage coil”
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.
How does a superconducting coil work?
This system includes the superconducting coil, a magnet and the coil protection. 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.
What is the storage capacity of a superconductor coil?
The direct current that flows through the superconducting material experiences very little resistance so the only significant losses are associated with keeping the coils cool. The storage capacity of SMES is the product of the self inductance of the coil and the square of the current flowing through it: E = 12LI2 E = 1 2 L I 2
What is a good percentage of useable energy in a coil?
In Eq. (3), is the transport current in the coil when fully charged. Ideally, the percentage of useable energy, , should be close to 100%, requiring a very high value of . As this is not practically possible, due to the superconducting limitations, a reasonable target of 90% is assumed.
Does a superconducting coil have a maximum charging rate?
This means that there exists a maximum charging rate for the superconducting material, given that the magnitude of the magnetic field determines the flux captured by the superconducting coil. In general power systems look to maximize the current they are able to handle.
How long does it take a superconducting coil to cool?
Advances have been made in the performance of superconducting materials. Furthermore, the reliability and efficiency of refrigeration systems has improved significantly. At the moment it takes four months to cool the coil from room temperature to its operating temperature.
