Abstract
The invention relates to a tank for storing liquefied gas, in particular liquefied hydrogen, the tank comprising a sealed shell that defines a storage space between a lower end and an upper end, the tank comprising a circuit that is fluidically connected to the storage space for filling with and/or drawing off fluid, characterized in that the tank comprises, in the storage space, a set of walls forming a trough that is located in the upper portion of the storage space and is open in the direction of the upper end of the storage space.
Claims15
A movable tank for storing and delivering liquefied gas, the movable tank comprising
- a fluid tight shell delimiting a storage volume between a lower end and an upper end, the fluid tight shell extending in a main direction that is horizontal when the tank is in usage configuration, the fluid tight shell being surrounded by a second shell with a thermally insulated space under vacuum;
- and
- a circuit fluidically linked to the rage volume for filling and/or withdrawing fluid,
- wherein the movable tank further comprises, in the storage volume, a set of walls forming a bowl that is located in r pa storage volume and open toward the upper end of the storage volume,
- wherein the bowl extends in the main direction,
- wherein the volume delimited by the bowl is in communication with the rest of the storage volume of the tank at least at an upper edge of the bowl,
- wherein at least a part of the set of walls forming the bowl is made of a flexible material.
