The project Zero-Regio, co-financed by the European Commission, aims at demonstrating hydrogen infrastructure and fuel-cell passenger vehicles in European cities. Demonstration activities are undergoing in Germany and Italy. Hydrogen from two different sources – chemical by-product in Germany and natural gas reforming in Italy will be used in the demonstration. The present paper focuses on the filling station in Frankfurt/Germany. The designing and construction of the refuelling infrastructure and the first experience are presented. Significant parts of this infrastructure are

- a ionic fluid compressor

- a 1000 bar transport line of about 1.7 km from hydrogen source to the filling station - a conventional multi-fuel service station - refuelling dispensers for CGH2 at 350 bar and 700 bar The above infrastructure is in place by the end of 2006. Fleet demonstration is planned for three years.
