6 FAQs about [Superconducting coil energy storage picture]

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 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 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.

What is a magnetized superconducting coil?

The magnetized superconducting coil is the most essential component of the Superconductive Magnetic Energy Storage (SMES) System. Conductors made up of several tiny strands of niobium titanium (NbTi) alloy inserted in a copper substrate are used in winding majority of superconducting coils .

How to design a superconducting coil system?

When designing an SMES system, the superconducting coil structure must have the best performance depending on the application for which the SMES will be used. The general objective, apart from the minimization of the production cost and the maximization of the discharge speed etc., is to abase the losses over the charges/discharges of the system.

Why do superconducting coils have a ferromagnetic core?

Generally, in the superconducting coils, there exists a ferromagnetic core that promotes the energy storage capacity of SMES due to its ability to store, at low current density, a massive amount of energy. For elevated gain the core configuration is “closed core (CC)”. The configuration of (CC) lodges the volume both outside and inside the coil.
