With the European "Green Deal", the goal of climate neutrality was set for the year 2050. In the course of the energy turnaround necessary for this, it is increasingly necessary today and in the future, in addition to the fundamental conversion to resource-saving processes, to design the entire process from energy generation to the consumer as sustainably as possible and thus minimise greenhouse gas emissions. On the one hand, this includes the efficient design of conversion processes, for example in the generation of electrical energy from renewable sources or in innovative drive concepts. On the other hand, topics such as minimising losses in electricity transport and energy storage, as well as the necessary stabilisation of the grids, are irrevocably linked to efficiency issues in this context. One technology that has great potential with regard to the points described above is superconductor technology. Superconductors are materials whose electrical resistance abruptly approaches zero when the temperature drops below the so-called transition temperature. Superconductor-based cables can transport electricity without losses, provided they are cooled to sufficiently low temperatures by appropriate systems. The current density is many times higher than that of conventional cable materials with the same cross-section, such as copper or aluminium. Together with the fact that superconducting cables, unlike standard cables, are completely electromagnetically and thermally neutral to the outside and do not affect the environment in any way, this represents a decisive advantage of superconducting materials. In the case of pure transmission lines, this has a direct effect on the required construction space and route widths.
