抄録

It is expected that liquid hydrogen (LH2) will be utilized for energy transportation and storage. The LH2 maintained in storage tanks is capable of generating electric power for a long time through fuel cells (FCs) without emission of carbon dioxide (CO2), and can cool high-temperature superconducting (HTS) machines, such as SMES and HTS cable, as well. We propose a hybrid energy transportation system composed of LH2 transfer pipeline, a FC system and HTS cable. We studied the power efficiency of the hybrid system and the pipeline design. We estimated the loss in the LH2 transfer pipeline with HTS cable and optimized the pipeline design. It was found that the hybrid energy transportation system has lower loss than conventional electric power cable. Since this system can transport not only LH2, but also large electric power with small loss, twice the amount of electric power can be supplied when large power load is required at peak times.
