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 control conduit for liquid hydrogen offloading is configured to couple a controller of a liquid hydrogen offload system to a liquid hydrogen tanker. The control conduit includes a control line and a gas detector. The control line is configured to transmit a control signal from the controller to the liquid hydrogen tanker. The gas detector is configured to detect hydrogen gas and provide a gas detector signal to the controller. The gas detector is secured to the control line at a predetermined distance from a tanker connection end of the control line.

To enable a hydrogen tank to be efficiently filled with hydrogen even when the hydrogen tank has a large capacity, hydrogen filling at the nozzle flow is prohibited when the nozzle flow of a nozzle is larger than the receptacle flow of a receptacle or when the receptacle flow is unknown under the condition that the nozzle and the receptacle can be connected to each other.

Method and device for controlling the quantity of liquid contained in a cartridge for an aerosol generating device, wherein the cartridge has a container and a liquid contained in the container and wherein, according to which is measured the quantity of liquid contained in the cartridge; and compared the quantity of liquid with a reference quantity of liquid.

An information processing device has a prediction unit and a business hour decision unit. The prediction unit predicts a demand for hydrogen at a hydrogen station through the use of a demand prediction model that is a learned model generated in advance through mechanical learning and that receives at least a behavioral pattern of a client and outputs the predicted demand for hydrogen. The business hour decision unit decides business hours of the hydrogen station based on the predicted demand for hydrogen.

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.

A computer-controlled method of automatically purging and precooling a hydrogen fuel line prior to transferring hydrogen fuel from a source to a storage tank includes purging moisture from a hydrogen fuel line. The hydrogen fuel line is configured to fluidically couple a hydrogen tanker storage tank and a fueling station storage tank, the hydrogen storage tanker storage tank and the fueling station storage tank configured to store liquid hydrogen. The method also includes pre-cooling the hydrogen fuel line, causing hydrogen fuel to flow through the hydrogen fuel line to re-fill the fueling station storage tank, and expelling residual hydrogen fuel from the hydrogen fuel line when the fueling station storage tank re-filling is complete.
