HYDROGEN FUELING STATION PRIORITY PANEL WITH OPTIMAL STORAGE BANK SELECTION
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.

The method for managing the supply of hydrogen to moving vehicles (1) from hydrogen distributed by distribution stations (7) comprises at least the following steps: a) collecting, by at least two sensors (2, 3) on board a vehicle (1), at least two parameters relating to the vehicle (1) during its movement, including at least the location of the vehicle, b) transmitting these parameters to a control module (5), c) collecting, by at least one sensor (12), at least one parameter relating to the hydrogen available in a distribution station (7), d) transmitting this parameter to the control module (5), e) identifying at least one hydrogen distribution station (7) while the vehicle (1) is moving, f) informing the user of the vehicle (1) of the available hydrogen distribution stations (7) and of the hydrogen supply conditions in the identified distribution stations.
MOBILE FUEL DISTRIBUTION STATION
A fuel distribution station includes a first fuel tank for releasably holding a first fuel, and a second fuel tank for releasably holding a second fuel. A connection member extends between the first fuel tank and the second fuel tank, and provides a rigid connection between the first fuel tank and the second fuel tank. A support structure supports the first fuel tank and the second fuel tank in an elevated position a predetermined distance above ground, sufficient to allow for passage of land vehicles beneath the support structure during a fueling operation. A control system is utilized for selectively permitting and monitoring a discharge of fuel from the first fuel tank and the second fuel tank to the land vehicles during the fueling operation.

Process and device for filling tanks with pressurized gas
Leak testing is performed after filling a first tank with pressurized gas and before filling a second tank with the same via a filling circuit including first and second isolation valves. After the first tank is filled, the pressure of gas trapped between the two closed isolation valves is measured. If the pressure is below a predetermined threshold, the first isolation valve is opened until the pressure reaches or exceeds the predetermined threshold, at which time the first isolation valve is closed and the second isolation valve is opened so that the leak test may be performed. If the pressure is otherwise at or above the threshold, the leak test is performed.
Method for minimizing power demand for hydrogen refueling station
A direct fueling station and a method of refueling are provided. The station includes an insulated tank for storing a liquefied fuel, a pump, at least a heat exchanger, a control unit, a dispenser including a flow meter, a flow control device, and at least one sensor for testing pressure and/or temperature. The heat exchanger converts liquefied fuel from pump into a gaseous fuel, which is added into an onboard fuel tank in a vehicle. The control unit includes one or more programs used to coordinate with the pump, the flow meter, the flow control device, and/or the sensor(s) so as to control a refueling method. A peak electrical power requirement is less than that determined by the product of a rated volumetric flow rate of the pump and a rated pumping pressure adequate for a fill pressure of the vehicle. A computer implemented system having the program(s) is also provided.
