Mobile hydrogen delivery system
A mobile hydrogen delivery system for delivering a compressed stream of hydrogen at pressures up to 15000 psig. The mobile hydrogen delivery system includes a hydrogen compression system, a gaseous hydrogen storage system, and a delivery system for supplying hydrogen to end users. A mobile platform supports the hydrogen compression system, the gaseous hydrogen storage system, and the dispensing system. The mobile platform may be any platform, such as a trailer, capable of being pulled, pushed, or supported by any type of vehicle, such a truck, train, boat, tractor, etc.
1. A mobile hydrogen delivery system comprising:
a metal hydride hydrogen compressor for storing hydrogen and providing a low pressure stream of hydrogen;
a mechanical hydrogen compressor for receiving said low pressure stream of hydrogen and providing a high pressure stream of hydrogen at a pressure higher than the pressure of said low pressure stream of hydrogen;
a gaseous hydrogen storage system including one or more pressure containment vessels for receiving and storing said high pressure stream of hydrogen;
a hydrogen dispensing system for dispensing said low pressure stream of hydrogen from said metal hydride storage system and said high pressure stream of hydrogen from said gaseous hydrogen storage system; and
a mobile platform for supporting said metal hydride storage system, said mechanical hydrogen compressor, said gaseous hydrogen storage system, and said hydrogen delivery system.
2. The mobile hydrogen delivery system according to claim 1 , wherein said one or more pressure containment vessels comprise two or more pressure containment vessels, and said hydrogen dispensing system dispenses hydrogen from said two or more pressure containment vessels in a cascading manner.
3. The mobile hydrogen delivery system according to claim 1 , wherein said metal hydride compressor is a single stage compressor.
4. The mobile hydrogen delivery system according to claim 1 , wherein said metal hydride compressor is a multi-stage compressor.
5. The mobile hydrogen delivery system according to claim 1 , wherein said low pressure stream of hydrogen has a pressure up to 2000 psig.
6. The mobile hydrogen delivery system according to claim 1 , wherein said high pressure stream of hydrogen has a pressure up to 15000 psig.
7. The mobile hydrogen delivery system according to claim 1 further comprising a hydrogen generator for generating said hydrogen supply stream and supplying said hydrogen supply stream to said metal hydride hydrogen compressor.
8. The mobile hydrogen delivery system according to claim 7 , wherein said hydrogen generator comprises one or more selected from a hydrogen reformer, a chemical hydride reactor, and an electrolyzer.
9. The mobile hydrogen delivery system according to claim 8 , wherein said chemical hydride reactor reacts a water reactive chemical hydride with water to produce gaseous hydrogen.
10. The mobile hydrogen delivery system according to claim 9 , wherein said water reactive chemical hydride is selected from alkali metal hydrides, alkali metal borohydrides, alkaline earth metal hydrides, alkaline earth metal borohydrides, and combinations thereof.
11. The mobile hydrogen delivery system according to claim 8 , wherein said electrolyzer is powered by a solar generator.
12. The mobile hydrogen delivery system according to claim 11 , wherein said solar generator comprises one or more triple junction amorphous silicon solar cells.
13. The mobile hydrogen delivery system according to claim 1 further comprising a fuel cell and/or a hydrogen powered generator in gaseous communication with said hydrogen dispensing system.
