The AVRC (Advanced Vehicle Research Center) in Raleigh, North Carolina, and North Carolina State University Solar Center have developed a design and build plan for a portable hydrogen refueling station. The project was funded with a US Department of Energy (DOE) grant.

AVRC and NCSU have drafted a complete plan to “build it yourself.” The plan has drawings, bill of materials, safety considerations, component suppliers, costs, etc. The station has not actually been built yet.
The station’s concept design calls for it to fit in a portable container which can be transported on the bed of a truck to specific utilization sites. The station can then be removed from the truck bed and set up as a temporary fueling station wherever needed.
The station is designed to produce its own electricity and carry its own water supply. Electricity for all the station’s equipment will be provided by an onboard diesel generator and water is supplied by a built-in storage tank. However, the design could easily be modified to incorporate utility supplied electricity and water or electricity produced by alternative means, such as a photovoltaic system.
A Hogen RE 40 hydrogen generator has been selected for the basic design. This generator is capable of producing approximately 40 SCFH, or 960 SCFD, of fuel grade hydrogen by electrolysis. For a vehicle such as the Honda FCX, which when full has a fuel volume of 1,592 ft3, this production rate will allow approximately 4.2 vehicles to be refueled per week.
The cost of materials according to the plan bill of materials is about $300,000 (not counting the truck or trailer platform). Construction costs should add another $100,000+.
