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 storage system for storing a cryogenic medium. The storage system includes a dual-wall cryogenic tank having an inner storage container for receiving the cryogenic medium and an outer container which surrounds the inner storage container. An evacuated hollow space is arranged between the inner storage container and outer container. A removal line serving as a removal duct forms a fluidic connection from the inner space of the inner storage container to a consumer connection. A first controllable line shut-off valve and a first heat exchanger are arranged in the removal duct. The storage system is operable such that, in the event of a crash, a shutdown of the storage system and escaping of the stored cryogenic medium is prevented. This is achieved via a first heat exchanger arranged within the evacuated hollow space, and a line shut-off valve which is arranged in the removal line. The line shut-off valve is operable, in the event of a fracture of a fluid-carrying connection, to automatically shut off fluid flow of the cryogenic medium.

A marine vessel and method for carbon capture and sequestration are described. The marine vessel includes a buoyant hull, a cryogenic storage tank within the hull, and a gaseous carbon dioxide loading manifold. The marine vessel also includes a carbon dioxide liquefaction system in fluid communication with the cryogenic storage tank downstream of the carbon dioxide liquefaction system and with the gaseous carbon dioxide loading manifold upstream of the carbon dioxide liquefaction system. Finally, the marine vessel includes a carbon dioxide supercritical system in fluid communication with the cryogenic storage tank. In operation, the marine vessel moves between multiple locations, where gaseous carbon dioxide is onboarded, liquified and stored. Thereafter, the marine vessel transports the liquified carbon dioxide to a location adjacent an offshore geological reservoir. The liquefied carbon dioxide is then pressurized to produce supercritical carbon dioxide, which is then injected directly into the reservoir from the marine vessel.

Plant and method for storing and distributing pressurized liquefied cryogenic fluid, comprising a liquefied gas source and a distribution member, comprising a first fluid inlet connected to the liquefied gas source and a second end intended to be connected to a user of the pressurized liquefied gas supplied by the distribution member, the source comprising a first liquefied gas store configured to store and supply the liquefied gas to the distribution member at a first determined pressure, the source comprising a second liquefied gas store configured to store the liquefied gas at a second determined pressure which is lower than the first pressure, the plant comprising a connecting pipe having a valve assembly connecting the first and second liquefied gas stores, the plant comprising a filling pipe having a valve assembly and having a first end connected to the second liquefied gas store and a second end intended to be connected to a mobile store for supplying liquefied gas to fill the source.

According to aspects, hydrogen fueling systems and methods are provided, including vehicle-to-vehicle communication techniques, hydrogen cooling techniques and/or hydrogen dispenser control techniques that facilitate improving aspects of a hydrogen fueling station.

The filling module includes: a first receptacle to be coupled to a first filling nozzle on a gas station side; a second receptacle to be coupled to a second filling nozzle on the gas station side; a first transmitter to transmit infrared rays to a first receiver disposed on an end portion of the first filling nozzle, the first transmitter being provided near the first receptacle; a second transmitter to transmit infrared rays to a second receiver disposed on an end portion of the second filling nozzle, the second transmitter being provided near the second receptacle; and first and second screen portions that project toward the gas station, the first and second screen portions being provided between the first transmitter and the second transmitter.

A bayonet coupling system includes a bayonet, a bayonet coupler, and a seal. The bayonet includes a bayonet tube configured to enable the flow of hydrogen fuel therethrough, and a flange coupled to the bayonet tube. The seal is configured to surround the bayonet tube and contact the flange along one side of the flange. The bayonet coupler includes a bayonet coupler tube having an inside diameter larger than an outside diameter of the bayonet tube, the bayonet coupler tube configured to receive the bayonet tube and to seal against the flange at the seal. The bayonet coupler is fixedly mounted directly or indirectly to a hydrogen storage tank such that a longitudinal axis of the bayonet coupler is inclined a predetermined angle with respect to horizontal to prevent a substantial thermal gradient from forming at the seal.

A process for transferring hydrogen from a first tank wherein the hydrogen is in an initial liquid state at a pressure of the order of 10 bar to a second tank wherein the hydrogen is in a final state at a pressure greater than or equal to 500 bar. The process includes: a first pumping step of the hydrogen from the initial state thereof to an intermediate state wherein the hydrogen has a pressure greater than that of the initial state thereof; and a second pumping step of the hydrogen from the intermediate state thereof to bring it to the final state thereof. The first pumping step and the second pumping step are carried out respectively by mutually separate first compression and second compression elements.

A flow control panel is configured to control a flow of fuel from a storage bank to a dispenser. The flow control panel includes input and output flow controllers, and input and output ports, each output port coupled to a respective dispenser port. Each output flow controller is coupled to a respective input port and a respective output port, and is configured to enable the flow of fuel from the input port and the output port. A processor is configured to control the input flow controllers and the output flow controllers. The processor is coupled to a memory storing instructions that when executed by the processor cause the processor to: receive a desired fuel pressure value from a dispenser; receive indications of fuel pressures within each of the storage banks; select a desired storage bank having the lowest fuel pressure among the storage banks that have fuel pressures greater than the desired fuel pressure; and activate a desired input port and a desired output port to enable fluid flow from the desired storage bank to the dispenser.
