A hydrogen storage system and a method for controlling the same includes a detection device that detects a first hydrogen pressure decompressed by a regulator using a first pressure sensor in the hydrogen storage system and a processor that predicts generation of noise at the regulator based on a change rate of the first hydrogen pressure during hydrogen charging and stops the hydrogen charging.

A system and a method for dispensing a liquefied fuel (e.g., hydrogen) are provided. The system includes a cryotank for storing a liquefied fuel, a first liquid pump and a second liquid pump. The first pump has a first maximum flow rate and pumps a first stream of the liquefied fuel having a first pressure. The second pump has a second and lower maximum flow rate, and pumps a second stream of the liquefied fuel has a second and higher pressure. Each pump is connected with a heat exchanger to vaporize a stream of the liquefied fuel to provide a respective vaporized substream. Each pump is also connected with a mixer, which combines the respective vaporized substream and a respective second substream of the liquefied fuel to provide a respective gaseous fuel stream. The gaseous fuel streams can be separately or jointly dispensed to one or more vehicles through a piping manifold and at least one dispenser.

The present invention relates to bulk metallic glass (BMG) structures used for hydrogen applications such as hydrogen infrastructure and vehicle applications. The BMG structure may include a main body with at least one opening, wherein the main body is made from a BMG material. The BMG structure may be configured to receive, store, transport and/or dispense hydrogen fuel in a form of fluid including one of gas, liquid, compressed gas or liquid, cryo-compressed hydrogen, and a combination thereof. The BMG structure may be configured to be under a direct exposure to hydrogen, wherein hydrogen is on the internal surface of the structure and is not on the exterior of the structure during operation.

An automatic obstruction device for closing a filling circuit for filling a tank with fluid includes: a movable element movable between a non-obstruction position of the filling circuit, in which the movable element offers resistance to the fluid compatible with the filling of the tank, and an obstruction position of the filling circuit, in which the movable offers a resistance to the fluid that is incompatible with the filling of the tank; a holding element of the movable element holding the movable element in the non-obstruction position, and allowing movement of the movable element toward the obstruction position; and a first device of non-reversible movement or of non-reversible modification of the holding element allowing movement of the movable element toward the obstruction position, and being controllable by a control device.

A fuel delivery and storage system is provided. A further aspect employs a remote central controller and/or software instructions which receive sensor data from stationary and bulk fuel storage tanks, portable distribution tanks, and end use tanks. Another aspect of the present system senses and transmits tank or hydrogen fuel characteristics including temperature, pressure, filled volume, contaminants, refilling cycle life and environmental hazards. Still another aspect includes a group of hydrogen fuel tanks which is pre-assembled with sensor, valve, microprocessor and transmitter components, at least some of which are within an insulator.

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 system and a method for filling a tank are provided. The tank filling system includes tanks that are filled with predetermined fluid and a manifold that is coupled to each of the plurality of tanks in a communication manner. A first flow passage is connected to a first inlet of the manifold to supply the fluid to be filled into the plurality of tanks to the manifold and a second flow passage is connected to a second inlet of the manifold spaced apart from the first inlet of the manifold by a predetermined distance to supply the fluid to be filled into the plurality of tanks to the manifold. A controller opens and closes the first flow passage and the second flow passage.
