Abstract
A liquefied hydrogen transport method includes connecting first and second loading arms to the manifold while vacuum insulation double tubes of the first and second loading arms are filled with hydrogen gas and air is mixed in piggyback lines; supplying an inactive gas to one of the piggyback lines of the first and second loading arms and taking in a gas mixture of an inactive gas and air from the other of the piggyback lines of the first and second loading arms; supplying hydrogen gas to one of the piggyback lines of the first and second loading arms and taking in a gas mixture of hydrogen gas and an inactive gas from the other of the piggyback lines of the first and second lading arms; and transporting liquefied hydrogen through any one of the vacuum insulation double tubes of the first and second loading arms.
