6 FAQs about [Superconducting coil energy storage formula]

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 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.

How does a superconducting coil withstand a large magnetic field?

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.

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.
