A cryogenic storage vessel (1) for a first cryogenic liquid (typically LNG) comprises an inner liquid-holding container (2) and an outer container (4). The outer container (4) defines a jacket for the inner container (2). There is a closed evacuated space 6 between the container (2) and the container (4). The liquid- holding volume of the inner container (2) or the outer surface of the inner container (2) is in heat exchange contact with a heat exchange member (22) defining a passage for a second cryogenic liquid (typically liquid nitrogen) that boils at atmospheric pressure at a lower temperature than the fast cryogenic liquid. The cryogenic storage vessel (1) may form part of a vehicle refuelling station. Passage of the second cryogenic liquid through the heat exchange member (22) is able to maintain the first cryogenic liquid in subcooled state. |
