Superconducting magnetic energy storage
OverviewAdvantages over other energy storage methodsCurrent useSystem architectureWorking principleSolenoid versus toroidLow-temperature versus high-temperature superconductorsCostSuperconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which 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. A typical SMES system includes three parts: superconducting coil, power conditioning system a
