Transport Of Gaseous Hydrogen

Road transport of gaseous hydrogen is presently carried out using trucks with steel cylinders of up to 90 litres at 200 – 250 bar pressure or large seamless cylinders called “tubes” of up to 3000 litres at 200 – 250 bar. For transport in larger scale pressure of up to 500-600 bars or even higher may be employed. A 40 tons truck delivers about 26 tons gasoline to a conventional gasoline filling station. A 40 ton truck carrying compressed hydrogen can deliver only 400 kilograms [PFL] , because of the weight of the 200 bar pressure vessels.

Compression of hydrogen is carried out in the same way as for natural gas. It is sometimes even possible to use the same compressors, as long as the appropriate gaskets (e.g. Teflon) are used and provided the compressed gas can be guaranteed to be oil free. (ZittelW:1996) Depending on the desired use, hydrogen must be either compressed or liquefied. In most cases, however, high-pressure gaseous hydrogen is preferred over liquid hydrogen.
