Hydrogen-powered aviation in Germany: A macroeconomic perspective and methodological approach of fuel supply chain integration into an economy-wide dataset.

The hydrogen (H2) momentum affects the aviation sector. However, a macroeconomic consideration is currently missing. To address this research gap, the paper derives a methodology for evaluating macroeconomic effects of H2 in aviation and applies this approach to Germany. Three goals are addressed: (1) Construction of a German macroeconomic database. (2) Translation of H2 supply chains to the system of national accounts. (3) Implementation of H2-powered aviation into the macroeconomic data framework. The article presents an economy-wide database for analyzing H2-powered aviation. Subsequently, the paper highlights three H2 supply pathways, provides an exemplary techno-economic cost break-down for ten H2 components and translates them into the data framework. Eight relevant macroeconomic sectors for H2-powered aviation are identified and quantified. Overall, the paper contributes on a suitable foundation to apply the macroeconomic dataset and to conduct macroeconomic analyses on H2-powered aviation. Finally, the article highlights further research potential on job effects related to future H2 demand. • The hydrogen momentum affects the aviation sector, but a macroeconomic perspective is currently lacking. • This article derives a methodology for evaluating the macroeconomic effects of hydrogen use in aviation and applies this approach to an economy-wide dataset for Germany. • The study investigates three hydrogen supply pathways, provides an exemplary cost break-down for ten hydrogen components and translates them into a national data framework. • Eight macroeconomic sectors relevant for hydrogen-powered aviation are identified and quantified by assigning the respective techno-economic cost components. • The article highlights meaningful research potential on macroeconomic analyses of hydrogen-powered aviation and employment effects related to future hydrogen demands.
