Abstract: A method for storing and distributing liquefied hydrogen using an installation having a storage facility for liquid hydrogen, a source of gaseous hydrogen, a liquefier having an inlet connected to the source and an outlet connected to the liquid hydrogen storage facility, the storage facility having a liquid withdrawal pipe having an end connected to the liquid hydrogen storage facility and an end configured to be connected to at least one mobile tank, the method having a stage of liquefying gaseous hydrogen and a stage of transferring the liquefied hydrogen to the storage facility, wherein the liquefied hydrogen has a temperature below the bubble point of hydrogen at the storage pressure and further having a stage of transfer of liquid hydrogen directly to the tank at a temperature between the saturation temperature at the pressure of the liquid and a temperature above the solidification temperature of the hydrogen.

Abstract: The present invention relates to a skid-mounted cold box and its prefabricated structure and assembly method. Each prefabricated structure includes a framework and a first panel that is used to enclose sides of the framework. Ring beams of two adjacent prefabricated structures are connected through bolts on site. A second panel connected through bolts encloses the gap between ring beams of the two adjacent prefabricated structures from sides. The present invention cancels all field welding seams and omits the field welding and nondestructive testing operations. The crane can be dismissed after the upper prefabricated structure of the cold box is lifted into place and bolts corresponding to columns on ring beams are connected. The present invention guarantees the connection strength of steel structures relying on bolt-based connection between ring beams and the second panel connected through bolts guarantees the airtightness of the cold box. This effectively reduces field assembly work and saves time and cost.
