Abstract

In order to provide hydrogen as a transportation fuel, service stations are provided with apparatus for performing the hydrocarbon to hydrogen conversion. The hydrocarbon product applied to the hydrocarbon to hydrogen converter can be distributed to the service station as gasoline/diesel fuel or as a separate hydrocarbon including natural gas. The hydrogen can be stored in a storage facility at the service station and dispensed to users as required. This distribution system eliminates the need for hydrocarbon to hydrogen converters in the each fuel cell powered automobile. This distribution system also eliminates the need for a separate dedicated hydrogen distribution system. In addition, the distribution of hydrogen can co-exist with the distribution of gasoline and diesel fuels providing for a convenient transition period. The carbon dioxide byproduct of the hydrocarbon to hydrogen conversion can be separately collected and forwarded to facilities requiring this material thus eliminating the emission of polluting gases if the hydrogen from hydrocarbon conversion done on each fuel cell powered vehicle.

Claims

1. A method for the distribution of hydrogen to vehicles powered by fuel cells, the method comprising:

storing at least one selected hydrocarbon at a local distribution facility

producing hydrogen by a hydrocarbon-to-hydrogen process at the local distribution facility; and

dispensing the hydrogen into a storage unit in the vehicles.

2. The method as recited in claim 1 further comprising storing hydrogen produced by the hydrocarbon to hydrogen process at the local distribution facility.

3. The method as recited in claim 1 wherein the hydrocarbon to hydrogen process produces at least one byproduct, the method further comprising storing the byproduct of the hydrocarbon to hydrogen produced at the local facility.

4. The method as recited in claim 3 further comprising dispensing the byproduct(s) of the hydrocarbon process into a transportation vehicle.

5. The method as recited in claim 1 further comprising storing and dispensing at least one selected hydrocarbon to vehicle.

6. The method as recited in claim 5 wherein the hydrocarbon and the selected hydrocarbon may be the same hydrocarbon.

7. A local distribution facility for providing fuel to automotive vehicles powered by a fuel cell, the facility comprising:

storage apparatus storing at least one selected hydrocarbon product;

a converter for converting the selected hydrocarbon product to hydrogen (and associated byproduct(s)); and

a dispenser for dispensing the hydrogen converted from the selected hydrocarbon product to a storage unit in the vehicle.

8. The local distribution facility as recited in claim 7 further comprising a storage unit for storing the hydrogen from the converter.

9. The local distribution facility as recited in claim 7 further comprising dispensing apparatus for storing and dispensing to an automotive vehicle at least one preselected hydrocarbon product.

10. The local distribution facility as recited in claim 7 wherein the hydrocarbon to hydrogen conversion results in at least one by-product, the local distribution system including a second storage apparatus for capturing and storing the by-product.

11. The local distribution facility as recited in claim 10 further comprising a second dispensing unit for transferring the byproduct to a transportation unit.

12. The local distribution system as recited in claim 7 wherein the selected hydrocarbon and the preselected hydrocarbon are the same hydrocarbon.

13. The local distribution system as recited in claim 10 wherein the byproduct is selected from the group consisting of carbon monoxide and carbon dioxide.

14. A system for the distribution of hydrogen to vehicles powered by a fuel cell, the system comprising:

a hydrocarbon fuel production system, the production system providing at least one hydrocarbon material;

a distribution system; and

at least one local facility, the distribution system transferring the hydrocarbon material from the production system to the local facility;

the local facility including;

a storage unit for storing the hydrocarbon material;

a converter unit for converting the hydrocarbon material to hydrogen; and

a dispenser unit for dispensing the hydrogen to storage units in the vehicles.

15. The system as recited in claim 14 wherein the local facility further includes a second storage unit for storing the hydrogen prior to dispensing the hydrogen to vehicles.

16. The system recited in claim 14 wherein the local facility includes a second dispensing unit for dispensing hydrocarbons to vehicles.

17. The system as recited in claim 16 wherein the local facility includes a third storage unit, the third unit storing a second hydrocarbon material, the second hydrocarbon material being dispensed by the second dispensing unit.

18. The system as recited in claim 14 wherein the converter unit generates at least one byproduct when converting the hydrocarbon material to hydrogen, the local facility further including a second storage unit for storing the byproduct.
