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.

The disclosure generally describes an apparatus for simulating a refueling operation for a fuel cell electric vehicle (FCEV). The fuel is compressed hydrogen gas dispensed by hydrogen refueling station (HRS).

A quantity of gas is introduced into a gas reservoir via a filling station provided with a filling line. The quantity is measured. A signal is generated indicating a corrected quantity of transferred gas. The signal is obtained by adding a predetermined, positive or negative, corrective amount to the measured quantity of gas transferred.

A device for supplying pressurized fluid, comprising a first valve) and a second valve accommodating internal circuits, the first valve and the second valve including respective coupling members that form a quick-connection system for removably connecting the second valve to the first valve, the internal circuits including a set of one or more control valves the device including at least one manually actuable mobile control member for controlling the set of one or more control valves, between a first, rest position, in which the flow of fluid towards the outlet is prevented, and a second, active position, in which the flow of fluid towards the outlet is allowed, the quick-connection system including a connection piece for connecting the second valve to the first valve between a first position.

A refuelling assistance device that determines one of the following scenarios: (a) that consecutive refuelling operations of a first vehicle at corresponding different fuel stations have taken place without a communication link, and (b) that consecutive refuelling operations at a first fuel station for corresponding different vehicles have taken place without the communication link. In response to determining scenario (a), the control unit causes a communication module of the first vehicle to be checked for establishment of the communication link. In response to determining scenario (b), the control unit causes a communication module of the first fuel station to be checked for establishment of the communication link.

This invention can provide a hydrogen refueling system capable to reduce waiting time for refueling H.sub.2 to vehicles. The system is designed and operated to acquire the residual pressure in the vehicle the that connects to the dispenser, then to calculate sufficient conditions to perform complete refueling of the connected vehicle (in particular minimum pressure in buffers), and then to start H.sub.2 transfer to the vehicle as soon as the conditions are met. Waiting time can be further reduced with minimum investment by having a H.sub.2 dispenser with two H.sub.2 refueling hoses which has only one H.sub.2 flow control valve and/or only one H.sub.2 cooling heat exchanger and/or only one H.sub.2 flow metering system.

The disclosure provides a gas filling method. The gas filling method includes the following steps: an effective heat mass calculation step, which uses the heat capacity of the piping and the detection value of the gas temperature sensor to calculate the value of the effective heat mass related to the temporary pressure loss caused by the piping before gas-filling is started; a pressure loss parameter calculation step, which uses the detection value of the pressure sensor when the flow rate of the gas in the piping changes to calculate the value of the pressure loss parameter related to the pressure loss caused by the piping after the gas-filling is started; and a filling condition changing step, which changes the filling condition into a condition that is defined based on the value of the pressure loss parameter and gas-filling is continued.
