Transport of Hydrogen
In principle hydrogen can be transported by using all the discussed storage technologies. Cylinder sizes will be rather big corresponding to the technologies used.
In the Ruhr Basin and in Leuna there has been a pipeline grid for hydrogen with a length well over 100 km for several decades. World-wide there are about 1000 km of hydrogen pipelines in operation.
- Liquid hydrogen (LH2) can be transported with trucks either in special trailers or in containers. In the USA there even exists a pipeline for liquid hydrogen which is 400 metres long.
- Today pressurized hydrogen (GH2) is delivered in mobile pressure cylinders or in bundles by truck or train from producer to consumer. In addition there is an option to build a pipeline system for the delivery of hydrogen which would principally correspond to our present natural gas grid. Since the year 2007 there has been a 1,7 km long pressure hydrogen pipeline with 100 MPa (1000 bar) working pressure to supply a filling station with a 700 bar petrol pump in Hoechst near Frankfurt in Germany. An other option is in development since July 2006 officially. Within the the so called icefuel® project all eleven partner are focusing the basis for a new and innovative system for transport, storage and supply of energy based on cryogenic media as liquid hydrogen. This project is founded by the German ministry of research and educaton. Within this opportunity hydrogen can find the way in everybody’s home. For more details see: www.icefuel.com
Ships for the transport of liquid hydrogen could be very similar to today’s tankers for liquid natural gas. New concepts for ships especially for the transport of liquid hydrogen have been designed in detail as well.
As long as there are only small amounts of hydrogen to be transported from continent to continent transportation in containers makes sense. These containers for liquid hydrogen are standardised and they can be transported all over the world on ships, trains and trucks and be unloaded in every container-terminal.
