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, with transport costs similar ti CNG, the technology is proven. Most hydrogen is produced at the place of demand with ever 50 to 100 miles (160 km) an industrial production facility. the 1938- Rhine-Ruhr 240 km hydrogen pipeline is still in operation. As of 2004 there are 900 miles (1,400 km)of low pressure hydrogen pipelines in the USA and 930 miles (1,500 km) in Europe.
