The Japan hydrogen project, WE-NET (World Energy Net Work) have showed that LH2 (Liquid hydrogen) with large density would be the most promising medium for transporting and storing large mass hydrogen efficiently and economically. In the near future, a large mass liquid hydrogen storage for a ground tank and a ocean tanker will be needed, of which the commercial scale may be the same as the existing LNG storage system with several hundreds thousand cubic meter capacity. The conceptual designs of 200, 000m3 LH2 tankers and 50, 000m3 ground tanks have been studied. This study has concluded that the optimized thermal insulation structure for a mass storage tank should be developed. In order to evaluate thermal conductance of various devised insulation structures, we have manufactured a large scale experimental apparatus. This paper describes the conceptual designs of LH2 tankers and ground tanks, and also the abstract of the developed apparatus.
