A hydrogen infrastructure is the infrastructure of pipes and stations for distribution and sale of hydrogen fuel.
Hydrogen pipeline transport 
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, the technology is proven, however most hydrogen is produced on the place of demand with every 50 to 100 miles (80 to 161 km) an industrial production facility. As of 2004 there are 900 miles (1,448 km) of low pressure hydrogen pipelines in the USA and 930 miles (1,497 km) in Europe.
Hydrogen stations and hydrogen highways 
Hydrogen stations which are not situated near a hydrogen pipeline get supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen trailers, liquid hydrogen tank trucks or dedicated onsite production. Some firms as ITM Power are also providing solutions to make your own hydrogen (for use in the car) at home. A hydrogen highway is a chain of hydrogen-equipped filling stations and other infrastructure along a road or highway which allow hydrogen vehicles to travel.
South Carolina also has a hydrogen freeway in the works[when?]. There are currently[when?] two hydrogen fueling stations, both in Aiken and Columbia, SC. Additional stations are expected[when?] in places around South Carolina such as Charleston, Myrtle Beach, Greenville, and Florence. According to the South Carolina Hydrogen & Fuel Cell Alliance, the Columbia station has a current[when?] capacity of 120 kg a day, with future plans to develop on-site hydrogen production from electrolysis and reformation. The Aiken station has a current capacity of 80 kg. There is extensive funding for Hydrogen fuel cell research and infrastructure in South Carolina. The University of South Carolina, a founding member of the South Carolina Hydrogen & Fuel Cell Alliance, received 12.5 million dollars[when?] from the Department of Energy for its Future Fuels Program.
The California Hydrogen Highway is an initiative by the California Governor to implement a series of hydrogen refueling stations along that state. These stations are used to refuel hydrogen vehicles such as fuel cell vehicles and hydrogen combustion vehicles. As of July 2007 California had 179 fuel cell vehicles and twenty five stations were in operation, and ten more stations have been planned for assembly in California. However, there have already been[when?] three hydrogen fueling stations decommissioned.
In May 2010, UNIDO has launched, on behalf of the International Centre for Hydrogen Energy Technologies, a call for tender related to the supply and installation by the end of 2011 of a hydrogen production, storage and filling facility on the Golden Horn, in Istanbul. This station will be used for the refueling of a hydrogen fuel cell driven passenger boat as well as for that of a hydrogen internal combustion bus.
