A hydrogen tank assembly is provided for use in vehicles, such as aircraft. The hydrogen tank assembly has an inner tank wall, an outer tank wall, and an inert gas source. The inner tank wall defines a hydrogen tank volume that is surrounded by a shroud volume which is defined by the outer tank wall. The hydrogen tank volume is filled with cryogenic hydrogen and has a higher pressure than the shroud volume that is filled with an inert gas, such as helium. The counter-pressure of the inert gas prevents micro-cracks in the inner tank wall and increases the in-service life.

A dual-wall, vacuum-insulated container (30, 40) has an external wall (1), an internal wall (3) and there in-between a vacuum chamber (5), in which there is arranged a heat insulation device (2, 20). At least three temperature sensors (13, 13a, 13b, 14, 15) that are spaced apart from another recurringly register instantaneous temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) of the container (30, 40). At least in some points there is calculated a temperature course using a heat insulation model on the basis of the construction and material characteristics of the container and the heat radiation resulting therefrom, which temperature course contains at least two of the temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) registered. From the temperature course there is calculated a desired temperature value for the position of at least one further of the temperature sensors and compared with the actual temperature value actually registered by this temperature sensor. From the deviation between the desired temperature value and the actual temperature value there is detected a change of the heat insulation quality of the container.

A dry vapor cryogenic storage container includes an absorbent core made from a porous material that absorbs a liquid cryogen and releases the cryogen in vapor form as the absorbed liquid evaporates. Fluid channels are formed in the absorbent core to increase the available surface area through which the liquid cryogen can be absorbed. The core can absorb the cryogenic liquid much faster with inclusion of the fluid channels. The absorbent core can be made by cutting a cavity and drilling holes in a stack of calcium silicate panels. The cavity holds a contents container or an inner core. The inner core can be part of an extractor and made from porous material including fluid channels for absorbing liquid cryogen. Contents containers can be housed in the inner core.

The invention discloses a bimetallic cryogenic membrane storage compartment for liquefied natural gas (LNG) storage. The invention is based on the design of bimetallic membrane panels and two insulating panels to achieve two completely independent insulation spaces, fully meeting the relevant requirements of the amendments to the International Code for the Construction and Equipment of Ships Carrying Liquefied Natural Gas in Bulk (“IGC CODE”) adopted on May 22, 2014. The invention improves the safety of the cryogenic membrane storage compartment, reduces the limitation of free liquid level loading of liquid cargo in the cargo compartment, reduces the application and time consuming of low-temperature resistant glue in the construction process, and adopts the more mature and safe design method of welding bimetallic membrane panels and the environmental protection method of prefabricated foam insulation panels, thus reducing the construction workload, shortening the construction cycle and improving the safety of the equipment.

A hydrogen tank, preferably a tank for storing liquid hydrogen at low pressure in cryogenic condition, includes at least one gaseous hydrogen capture system. The system is provided with absorbent fillers configured to capture the gaseous hydrogen, the absorbent fillers being linked to at least a part of a wall of the tank, and/or to a skin arranged on an outer face of the tank, and/or to an outer jacket intended to implement an auxiliary function. The system has a reduced weight and is able to retain and store gaseous hydrogen which could escape from the tank so as to prevent it from being given off into the environment of the tank. The captured gaseous hydrogen is able to be restored later by the system.
