Abstract

A double-walled container for transporting and storing a liquified gas or cryogenic liquid at low temperature. The container has an inner liquified gas holding vessel and an outer shell enclosing the inner vessel. The outer shell is coaxial with the vessel and of such a size as to provide a closed insulated space all around it. The inner vessel is suspended by its ends within the outer shell, with one end of the vessel being rigidly connected to the adjacent end of the shell while the other opposite end of the vessel is slidably connected to the other adjacent end of the shell so as to allow thermal expansion of the inner vessel and outer shell with respect to each other. Closable feeding and exit pipes pass through the outer shell and the inner vessel for introducing and draining the liquified gas into and off from the inner vessel. This container is light weight and can be of very great size; it can be used for the international transportation of liquid hydrogen by air, sea, rail or road.
