As part of the VMo4Orte research project, a roadmap has been developed that uses the example of Hamburg Airport to outline what the introduction of hydrogen might look like for other medium-sized German and European airports. In the first few years up to around 2040, it can be assumed that hydrogen will be supplied in small quantities using special refuelling vehicles. As demand increases in the 2040s, an additional supply via a pipeline connection will become necessary. The delivery of hydrogen by pipeline must be in gaseous form due to the system design. As aircraft will primarily require hydrogen in liquid form for refuelling in the long term, a liquefaction plant will also be required at the airport. Storage tanks for the liquid hydrogen at the airport will also be necessary.
