Outline
With the significant integration of transportation and energy fields, the electrified and "green" energy consumption in transportation is an important technical solution for achieving the targets of carbon peak and carbon neutrality. The use of low-temperature energy as coolants for high-temperature superconductor (HTS) cables can simultaneously transport the electric energy and fuels, which can improve the energy transmission efficiency and reduce the overall costs for large-scale renewable energy transmission. For a 10 km transmission distance, a 1.5 kV/10 kA liquid hydrogen (LH2) energy pipeline structure for railway transportation is designed. Meanwhile, the effect of the arrangement angle of positive and negative bipolar HTS tapes on their critical currents was investigated by establishing a finite element simulation model of HTS cable. The maximum critical current was about 15 240 A in the parallel arrangement. Finally, the transmission losses of HTS cables and conventional copper cables with the same capacity (i.e., 15 MW/10 km) were compared. Results show that the transmission loss of 1.5 kV HTS cable was only 15% of that of 10 kV conventional AC cable, and it was also slightly lower than that at the 35 kV voltage level. The findings in this research can provide a feasible technical solution for LH2 HTS energy pipelines to be used for large-capacity combined hydrogen-electricity transmission.
