Superconducting technology applications in electric machines have long been pursued due to their significant advantages of higher efficiency and power density over conventional technology. However, in spite of many successful technology demonstrations, commercial adoption has been slow, presumably because the threshold for value versus cost and technology risk has not yet been crossed. One likely path for disruptive superconducting technology in commercial products could be in applications where its advantages become key enablers for systems which are not practical with conventional technology. To help systems engineers assess the viability of such future solutions, we present a technology roadmap for superconducting machines. The timeline considered was ten years to attain a Technology Readiness Level of 6+, with systems demonstrated in a relevant environment. Future projections, by definition, are based on the judgment of specialists, and can be subjective. Attempts have been made to obtain input from a broad set of organizations for an inclusive opinion.

Actually, MgB2 is the lightest superconducting compound. Its connection with lightweight metals like Ti (as barrier) and Al (as outer sheath) would result in a superconducting wire with the minimal mass. However, pure Al is mechanically soft metal to be used in drawn or rolled composite wires, especially if applied for the outer sheath, where it cannot provide the required densification of the boron powder inside. This study reports on a lightweight MgB2 wire sheathed with aluminum stabilized by nano-sized γ-Al2O3 particles (named HITEMAL) and protected against the reaction with magnesium by Ti diffusion barrier. Electrical and mechanical properties of single-core MgB2/Ti/HITEMAL wire made by internal magnesium diffusion (IMD) into boron were studied at low temperatures. It was found that the ultra-lightweight MgB2 wire exhibited high critical current densities and also tolerances to mechanical stress. This predetermines the potential use of such lightweight superconducting wires for aviation and space applications, and for powerful offshore wind generators, where reducing the mass of the system is required.

“…The emission of an all-electric aircraft is still distant because of the low energy density of present battery technology. Hybrid electric propulsion, on the other hand, is considered as a more practical design, in which power generator is drove by turbines and the propulsion system consists of electrical HTS motors [1][2][3][4][5][6]. The power requirement for a passenger aircraft ranges from 5 MW to 50 MW.…”

High temperature superconducting (HTS) tri-axial CORC cable has been a potential candidate for the transmission line used in an all-electric aircraft because of its advantages such as compactness, high power density and reduced usage of HTS tapes. A tri-axial CORC HTS cable (10 MW, 3 kV/2 kA) is being developed in University of Bath in cooperating with Airbus. AC/DC converters, generators and motors will induce harmonic currents in the power system of a hybrid electrical aircraft. It may considerably affect the AC loss of the transmission cable, which is one of the key factors determining the efficiency of the cable. This paper studies the transport AC losses of this tri-axial CORC cable and the influence of harmonic current on the losses. A finite element method (FEM) model has been developed based on T-A formulation to analyze the dynamic electromagnetic behavior of this tri-axial CORC cable. Analyses are performed under rated load with & without harmonic currents. Results show that the transport AC loss has a significant non-uniform distribution among three phases even under a three-phase balanced load. A small harmonic current (less than 10 %) can considerably increase the AC loss of the tri-axial cable (up to 40 %).
