Integrated gaseous fuel delivery system
An integrated gaseous fuel delivery system is provided. The system includes a storage tank to hold a gaseous fuel and a pressure regulation system disposed interior the storage tank and configured to regulate a pressure of gaseous fuel delivered from the storage tank.
1. An integrated gaseous fuel delivery system, comprising:
a storage tank to hold a gaseous fuel; and
a pressure regulation system disposed interior the storage tank and configured to regulate a pressure of gaseous fuel delivered from the storage tank, wherein the pressure regulation system is operated through a remote system external to the storage tank.
2. The fuel delivery system of claim 1 , wherein the pressure regulation system includes a main regulator.
3. The fuel delivery system of claim 2 , wherein the pressure regulation system includes a trim regulator.
4. The fuel delivery system of claim 1 , wherein the pressure regulation system includes at least one solenoid.
5. The fuel delivery system of claim 1 , wherein the gaseous fuel is hydrogen.
6. The fuel delivery system of claim 1 , wherein the storage tank is configured to store the gaseous fuel at a storage pressure and the pressure regulation system is configured to output a regulated pressure fuel from the storage pressure.
7. The fuel delivery system of claim 1 , wherein the pressure regulation system is operated through an electromagnetic coupling.
8. The fuel delivery system of claim 1 , further comprising at least one sensor or actuator electromagnetically coupled to the storage tank.
9. The fuel delivery system of claim 1 , further comprising a fuel line to an injector.
10. The fuel delivery system of claim 9 , wherein the fuel line is a double-walled fuel line.
11. A gaseous fuel power system for a vehicle, comprising:
an integrated fuel delivery system, including a storage tank to hold a gaseous fuel and a pressure regulation system;
a powerplant to convert energy from the gaseous fuel into energy useable to power the vehicle; and
an uninterrupted passage fluidically coupling the storage tank to the powerplant.
12. The fuel power system of claim 11 , wherein the powerplant is an internal combustion engine.
13. The fuel power system of claim 11 , wherein the powerplant is a fuel cell.
14. The fuel power system of claim 11 , wherein the gaseous fuel is hydrogen.
15. The fuel power system of claim 11 , wherein the integrated fuel delivery system includes an at least one solenoid and an at least one pressure regulator.
16. The fuel power system of claim 11 , wherein the integrated fuel delivery system includes an electromagnetically coupled control.
17. A method of reducing leaks in a gaseous fuel delivery system, the method comprising:
storing a gaseous fuel at a first pressure within a storage tank;
regulating pressure of the gaseous fuel to a second pressure, different than the first pressure, before the gaseous fuel exits the storage tank; and
delivering the gaseous fuel from the storage tank to a powerplant via a substantially uninterrupted passage.
18. The method of claim 17 , wherein regulating pressure of the gaseous fuel includes operating a pressure regulator internal the storage tank.
19. The method of claim 17 , wherein delivering the gaseous fuel includes passage through a single interface between the tank and the powerplant.
