|Abstract:||Superconducting Magnetic Energy Storage (SMES) systems have theoretically been considered for model applications in a potentially compact and practical form for domestic sustainable power. Using two different models, we have compared two different types of superconducting solenoids for this purpose. The optimal performance of helically wound solenoids of NbTi (or MgB2) wires are compared with that of pancake solenoids of the YBCO tape. The maximum energy storage of the coils has been obtained for various parameters and dimensions by optimizing core radius, coil length, and magnetic field strength. Helical solenoids made from NbTi wires are shown to somewhat outperform pancake coils made of YBCO-coated conductors. However, this consideration is, respectively, made at operation temperatures of 4.2 and 77 K. The viability of such compact SMES for “domestic” (or some “exotic”) sustainable energy systems is discussed.|
