A hydrogen filling station developed and built by Linde was officially put into service today at Hamburg airport.

The transportable supply unit is used to fill two fuel-cell-driven STILL tractors and a people-carrier which will, in future, be in daily use at the airport. The project, planned to last two years, was realised as a cooperation between the Hamburg Regional Initiative for Hydrogen and Fuel Cell Technology, Hamburg Airport, Wasserstoffgesellschaft Hamburg and The Linde Group.

$quot;Airport applications are particularly suitable as pilot projects for developing a local hydrogen infrastructure$quot;, explains Dr. Joachim Wolf, executive director of Hydrogen Solutions at Linde. $quot;The clear cut operating range and the central refuelling predestine this application for the use of hydrogen as emission-free fuel.$quot;

Airport manager Claus-Dieter Wehr said, $quot;The experts agree that hydrogen is an energy source with great potential for the future. This is why, together with our partners, we initiated the hydrogen research project at Hamburg airport. We are proud to be setting a good example in exploring alternative energies.$quot;

All the components of the filling station are built into a container only three metres long; the hydrogen is delivered by Linde in bundles of gas cylinders. Since the fuel-cell-driven tractors operate at an operating pressure of 350 bar and the people-carrier operates at 200 bar, two separate tapping systems are provided.

The entire installation is controlled by a programmable logic control which guarantees both automated filling and the highest possible standard of safety. Thanks to the use of a touchscreen monitor, operation is very user-friendly. The filling process takes seven minutes at most.
