  • Patent number: 12152731
    Abstract: The present disclosure discloses a quick-connecting receptacle for a liquid hydrogen storage tank. The quick-connecting receptacle comprises: a storage tank for storing liquid hydrogen; and a receptacle connecting an external transmission pipe and the storage tank so that liquid hydrogen introduced through the external transmission pipe is stored in the storage tank. The receptacle includes an upper receptacle connected to a lower end portion of the transmission pipe and a lower receptacle connected to an upper portion of the storage tank. The lower receptacle includes a cylinder member accommodated therein, and as the cylinder member moves up and down, liquid hydrogen or gaseous hydrogen is stored in the storage tank or liquid hydrogen or gaseous hydrogen is discharged from the storage tank to outside.

  • Publication number: 20240318905
    Abstract: The present disclosure relates to a hydrogen liquefaction device, which may comprise: a cradle for forming an accommodating space in which a mobile storage container capable of storing liquefied hydrogen or a mobility that uses liquefied hydrogen as a power source can be accommodated; and a liquefier installed on one side of the cradle, cooling hydrogen in a gaseous state supplied from outside to a temperature which is equal to or below liquefaction temperature to generate liquefied hydrogen in a liquid state so as to supply liquefied hydrogen to the mobile storage container or the mobility, or recover vaporized gas generated from the mobile storage container in which liquefied hydrogen is stored or from the mobility for re-liquefaction into liquefied hydrogen.

  • Publication number: 20240310115
    Abstract: The present disclosure relates to a hydrogen liquefaction device capable of liquefying gaseous hydrogen into a liquid state through multi-stage cooling by heat exchange between a heat pipe in which a refrigerant cooled by a cryocooler flows and hydrogen flowing through a micro-channel. The device may comprise a hydrogen pipe for connecting a hydrogen supply unit in which gaseous hydrogen is stored and a storage container in which liquid hydrogen liquefied in a liquid state is stored; and a heat exchange unit that cools hydrogen by at least one or more heat exchangers installed on the hydrogen pipe so that hydrogen being introduced from the hydrogen supply unit and flowing through the hydrogen pipe toward the storage container can be cooled and liquefied in a process of passing through the hydrogen pipe and be discharged to the storage container as liquid hydrogen.
