High-Temperature Superconductors: Technologies and Solutions for Naval Applications

Conference Paper


Abstract


  • Superconductors are materials that can carry significant current with essentially zero resistance, making them particularly useful for applications where high currents – or the generation of large magnetic fields – is required. Practical superconducting elements – either wires or tapes – can carry currents hundreds of times larger than copper wires of the same area, meaning the devices made with superconductors can be compact (e.g. up to 90% weight reduction in degaussing applications compared to their copper-based equivalents). The increased performance of what is intrinsically a quantum technology material is achieved with the application of cryocooling technology (TRL 9), utilising highly efficient cryocoolers, for instance Stirling cycle coolers. In the future, the parallel development of quantum optical solid-state cooling will revolutionise superconductor cooling technology and accelerate the deployment of superconducting technology in a wide range of naval applications.

    Recent improvements in the performance of ‘Second Generation’ (or 2G) High-Temperature Superconductors (HTS), coupled with enhanced simulation techniques, have opened new opportunities for HTS in naval applications.

    Here we provide a review of Naval applications where high currents and/or high magnetic fields are making possible enhanced capability in naval propulsion, mine countermeasures and energy generation. We discuss the developments in producing long lengths of high-performance and high-homogeneity HTS tape, and how the maturation of these production techniques opens new opportunities for superconducting devices. We discuss the state-of-the-art and open issues associated with designing and simulating HTS-based devices and solutions. We then conclude with an outlook of how HTS-based devices can continue to play a role in enhancing the capability or reducing drawbacks present in current solutions in Naval applications.
