Fostering Macroeconomic Research on Hydrogen-Powered Aviation: A Systematic Literature Review on General Equilibrium Models

Hydrogen is a promising fuel to decarbonize aviation, but macroeconomic studies are currently missing. Computable general equilibrium (CGE) models suitable conduct analyses and frequently employed in hydrogen aviation research. The main objective of this paper investigate existing CGE related (a) (b) derive research agenda for hydrogen-powered aviation. Therefore, the well-established method systematic literature review conducted. First, we provide an overview 18 hydrogen-related 27 aviation-related analyze with respect appropriate categories. Second, highlight key insights identify gaps both hydrogen- literature. Our findings comprise, inter alia, hydrogen’s current lack cost competitiveness relevance air transportation. Research include, among others, stronger focus on sustainable more holistic perspective transportation system. Third, implications including (I) consideration modeling approaches, (II) utilization interdisciplinary data scenarios, (III) geographical suitability, (IV) application diverse policy tools (V) perspective. work contributes meaningful foundation Moreover, recommend policymakers address perspectives use
