| 摘要 |
The boil-off gas discharged from a liquid hydrogen storage tank on a liquid hydrogen transport vessel (16) is introduced into the liquid hydrogen stored within liquid hydrogen storage tanks (19, 20) disposed on the ground by passing through a boil-off gas introduction path (17). At least a portion of the boil-off gas is re-liquefied by means of the cold temperature of the liquid hydrogen. The boil-off gas that was not re-liquefied and the gasified hydrogen generated as a consequence of the liquid hydrogen within the liquid hydrogen storage tanks (19, 20) gasifying are mixed with raw material hydrogen by being supplied to the raw material hydrogen path (11) of a liquid hydrogen production device (HS) by passing through a gasified hydrogen discharge path (21). The boil-off gas and the gasified hydrogen are re-liquefied by means of the liquid hydrogen production device (HS). |
