Embodiments of systems and methods for transporting fuel and carbon dioxide (CO2) 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 CO2 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 CO2. Insulation may provide temperature regulation for the fuel and CO2 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 CO2.

A cryogenic flux capacitor (CFC) storage system includes a CFC core module having an inner container comprising one of: (i) a vessel; and (ii) a membrane that contains a substrate material. Fluid paths in the substrate material distribute fluid during charging and discharging. Nanoporous media is attached to the substrate material that receives fluid via physical adsorption during charging. A thermally conductive support layer maintains position of the substrate material within the inner container. The thermally conductive support layer conductively distributes thermal energy within the inner container. An outer insulating container encompasses the CFC core module. At least one fluid conduit directs transfers of the fluid in a gaseous or liquid state from a source subsystem into the CFC core module during charging and the fluid in a gaseous state out of the CFC core module during discharging to a destination subsystem that utilizes the fluid in a gaseous state.

A gaseous hydrogen storage and distribution system with a cryogenic supply and a method for the cryogenic conversion of liquid hydrogen into high-pressure gaseous hydrogen are provided. The gaseous hydrogen storage and distribution system includes pressuring liquid hydrogen from a cryogenic tank using a low pressure liquid pump before vaporization within a relatively small vaporizer. The resulting high pressure gaseous hydrogen is transferred to a plurality of storage tanks at ambient temperature according to a desired fill sequence. The high pressure hydrogen gas is subsequently distributed from the storage tanks through a hydrogen fueling dispenser according to a desired dispensing sequence. The present system and method provide improvements in operational safety, eliminates the use of high pressure gas compressor, and minimizes boiling off and ventilation losses at a reduced cost when compared to existing thermal compression storage systems.

Example systems, methods, and apparats for refueling hydrogen aircraft are disclosed herein. An example multiphase hydrogen refueling system includes a liquid hydrogen (LH2) tank coupled to at least one of a cryo-compressed hydrogen (CcH2) tank and a gaseous hydrogen (GH2) tank; a liquid nitrogen (LN2) tank; and a hydrant coupled to the LH2 tank, the CcH2 tank, the GH2 tank, and the LN2 tank, the hydrant including: a transfer line to refuel an aircraft with at least LH2, CcH2, or GH2; a purge valve to purge the transfer line using at least one of nitrogen (N2) from the LN2 tank or GH2 from the GH2 tank; and a GH2 return line to transmit evaporated GH2 back to the GH2 tank.

Systems and methods for automatically purging by pneumatic ejection with a select pressurized media, gravity-accumulated hydrocarbon liquid dropout from a retrograde vapor waste liquid collection containment reservoir.

A system and method for recharging at least one fluid cylinder using a first fluid cylinder. The system uses a flow indicating switch which can comprise an internal magnetic source to detect the flow of fluid. The flow indicating switch is in communication with an electronic sequencing module. The electronic sequencing module controls the order and timing of discharge from the first fluid cylinder into the at least one fluid cylinder.

A device for filling pressurized gas tanks, including a fluid transfer circuit having an upstream end connected to a plurality of sources of pressurized fluid and a downstream end having at least one dispenser intended to be connected to a tank to be filled, the sources being connected in parallel, each source has a fluid outlet connected to a respective outlet valve, the transfer lines being connected in parallel to the at least one dispenser and each having a respective transfer valve, the transfer lines and the transfer valves being dimensioned so as to transfer a maximum transfer gas flow which is smaller than the maximum filling gas flow, the sum of a plurality of maximum transfer gas flows provided by a plurality of outlet valves and a plurality of transfer lines being greater than or equal to the maximum filling gas flow.

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.
