[Problem] When configuring a device for storing and supplying fluid, each components such as vessels, valves/pipes and the like, are placed independently outside a vessel that stores the fluid, and even if these components are small, the volume of the area between the components cannot be effectively used because each of them occupies the surrounding area, and when the total size of the device is limited, it is difficult to ensure a sufficient volume of the vessel that stores the fluid. The present invention provides a design for a configuration of a mechanism consisting of components such as valves/pipes and the like, that functions for storing and exhausting the fluid inside the storage vessel to innovatively improve the volume usage efficiency of the device.

A system and method is provided for transferring liquid argon from a bulk storage tank to a transport tank in which liquid argon is pumped through a tube arrangement within a heat exchanger and the tube arrangement is contacted by liquid nitrogen so that heat transfers from the liquid argon to the liquid nitrogen, thereby reducing the temperature, density and pressure of the liquid nitrogen prior to exiting the heat exchanger and flowing into the transport tank.

The invention relates to a system for providing a fluid, comprising at least a first and a second cryogenic container for storing the fluid, wherein the system comprises a first retrieval line connecting to the first cryogenic container for retrieving a first mass flow (M1) of fluid and a second retrieval line connecting to the second cryogenic container for retrieving a second mass flow (M2) of fluid, wherein the system comprises means, which are configured to establish two mass flows (M1, M2) of different dimensions such that in a first operational mode a hold time of the two cryogenic containers converges upon retrieval and/or in a second operational mode the hold time of the two cryogenic containers essentially decreases at the same rate if the hold times of the two cryogenic containers are essentially equal.

Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

A vehicle is equipped with a hydrogen tank that stores hydrogen, a fuel cell that generates electricity from the hydrogen in the hydrogen tank, a filling device 4 that fills a fuel cell vehicle with the hydrogen stored in the hydrogen tank, and a charger with which electricity generated by the fuel cell is charged to an electric vehicle. Using the vehicle, hydrogen and electricity are delivered to the home of a user.

A cryogenic storage system basically includes a first cryogenic storage tank, a second cryogenic storage tank, a fluid transfer line and a cryogenic containment structure. The first cryogenic storage tank has a first predetermined capacity of liquefied gas. The second cryogenic storage tank has a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank. The fluid transfer line is fluidly connected between the first cryogenic storage tank and the second cryogenic storage tank. The heat exchanger converts liquid exiting the first cryogenic storage tank to a higher pressure gas that is used as a motive force to move liquidized gas out of the second cryogenic storage.
