Hydrogen vehicles could be refueled at present gasoline stations by installing technology that can be manufactured today.
Hydrogen can be transported in natural-gas pipelines or in tankers, using existing petroleum infrastructure. Gasunie Research, of Groningen, Netherlands, is organizing NaturalHy, a program to test distribution of hydrogen, mixed with natural gas, in existing natural gas pipelines.
Since pipelines are the cheapest way to transport gaseous hydrogen, an effort is underway to promote the development of the International Renewable Hydrogen Transmission Demonstration Facility (IRHTDF).
The hydrogen infrastructure (for production, transport, storage, and dispensing) can be set up today for conventional internal combustion engine vehicles.
This infrastructure can then be available for the fuel-cell vehicles of the future.
Conversion to hydrogen will rely heavily on working with the existing petroleum infrastructure.
We will have to rely on petroleum for years to come. Converting now depends on working with petroleum companies to incorporate their existing market and infrastructure into needed means of producing, transporting, storing, and dispensing hydrogen.
Research is striving to improve renewable methods of generating hydrogen (from livestock waste, landfill biomass, wastewater sludge, chemical reactions, and electricity from solar, wind, and water power). Harvesting hydrogen from these sources can make it a completely renewable resource.
