US 2026/0287121 A1 · ENABLING HYDROGEN CONSUMPTION DURING REFILLING OF HYDROGEN

Abstract

A method in a hydrogen delivery system having a plurality of hydrogen fuel tanks (HFTs) and at least one HFT (aHFT) of the HFTs configured to maintain hydrogen fuel to consumers (fuel cells and fuel consumers) during refueling of the HFTs, the method including: determining whether or not HFTs are set up for refueling; responsive to HFTs being set up: before the refueling process begins: initiating disconnection of HFTs to close while maintaining connection of the aHFT to the fuel consumers; providing pressure and temperature of a high pressure line providing fuel to HFTs to a fueling station interface or providing a maximum or average pressure and temperature of HFTs to the fueling station interface without providing a maximum or average pressure and temperature of the a HFT; and after the refueling process: initiating connection of the HFTs to the consumers to provide hydrogen fuel thereto.

Dependent claims

A method in a hydrogen delivery system having a plurality of hydrogen fuel tanks with at least one hydrogen fuel tank of the plurality of hydrogen fuel tanks maintaining availability of hydrogen to one or more fuel consumers during refueling of the plurality of the hydrogen fuel tanks, the method performed by a controller and comprising:

determining whether or not the plurality of hydrogen fuel tanks is set up for refueling;
responsive to determining that the plurality of hydrogen fuel tanks is set up for refueling:
before a refueling process begins:
initiating disconnection of the plurality of hydrogen fuel tanks from the one or more fuel consumers while maintaining a connection of the one or more hydrogen fuel tanks to at least one of the one or more fuel consumers;
providing pressure and temperature of a high pressure line providing fuel to the plurality of hydrogen fuel tanks to a fueling station interface of a fueling station or providing a maximum or average pressure and temperature of the plurality of hydrogen fuel tanks to the fueling station interface without providing a maximum or average pressure and temperature of the at least one hydrogen fuel tank to the fueling station interface and
after the refueling process:
initiating connection of the plurality of hydrogen fuel tanks to the one or more fuel consumers where the plurality of hydrogen fuel tanks including the one or more hydrogen fuel tanks provide hydrogen fuel to the one or more fuel consumers.

4 more elements

initiating disconnection of the plurality of hydrogen fuel tanks from the one or more fuel consumers while maintaining a connection of the at least one hydrogen fuel tank to at least one of the one or more fuel consumers
providing pressure and temperature of a high pressure line providing fuel to the plurality of hydrogen fuel tanks to a fueling station interface of a fueling station or providing a maximum or average pressure and temperature of the plurality of hydrogen fuel tanks to the fueling station interface without providing a maximum or average pressure and temperature of the at least one hydrogen fuel tank to the fueling station interface;
and
after the refueling process:
initiating connection of the plurality of hydrogen fuel tanks to the one or more fuel consumers where the plurality of hydrogen fuel tanks including the at least one hydrogen fuel tank provide hydrogen fuel to the one or more fuel consumers.

12 more elements

A method in a continuous hydrogen delivery system having a plurality of hydrogen fuel tanks and at least one hydrogen fuel tank of the plurality of hydrogen fuel tanks configured to maintain availability of hydrogen to at least one of one or more fuel consumers during refueling of the hydrogen fuel tanks the method performed by a controller and comprising:

determining that the at least one of the one or more fuel consumers remains operating during the refueling;
responsive to the at least one of the one or more fuel consumer remains operating:
commanding an inline solenoid valve to the one or more fuel consumers to close while maintaining a connection of the at least one hydrogen fuel tank to the at least one of the one or more fuel consumers.
