Co-ordinating Zero Regio, Infraserv Höchst presented the development of the hydrogen-project on this year's Hannover Fair. After the successful commissioning of the multifuel-station in November 2006 at the industrial park Höchst an understanding of first experiences of the test-phasis were given to interested persons. For the third time Infraserv Höchst demonstrated the EC-funded project in Hannover.
