Summary

To utilize liquid and slush hydrogen at temperatures between 15 to 20 K as the refrigerant of HTS and MgB2 superconductors with a clean energy carrier without exhaust of CO2, a few methods are suggested. The boil-off gas of parahydrogen must be pure and can also be fed to PEFC for highly efficient electric power generation. If it were possible to construct long and thermally well-insulated parahydrogen transfer lines, for example, along highways, it would be possible to transfer high-current electric power through refrigerated HTS and MgB2 cables without loss. The technologies of combining liquid hydrogen and HTS, MgB2 superconductors will give rise to new solutions for clean energy use in communities around the world.
