Hydrogen (H2) is currently being investigated as a sustainable energy carrier for aircraft to decarbonise primarily short- and medium-haul aviation. Although hydrogen- powered aircraft can eliminate in-flight carbon dioxide and possibly reduce non-CO2 effects [1], research is required to initiate and mature the hydrogen supply infrastructure and daily airport operations for such aircraft. The GOLIAT (Ground Operations of LIquid hydrogen AircrafT) project [2] seeks to overcome the current obstacles in technologies, regulations, processes, and economics to make widespread daily use of hydrogen at airports. In the GOLIAT project, we will develop comprehensive liquid hydrogen (LH2) demand and supply-matching models for air transport ground infrastructures. Future analyses will provide techno-economic insights by comparing forward-looking scenarios. To initiate the modelling and analyses, we first need to define the scope and develop new scenarios based on currently available literature and knowledge...
