Analyzing the hydrogen supply chain for airports: Evaluating environmental impact, cost, sustainability, viability, and safety in various scenarios for implementation

It is a matter of great concern that the aviation industry, which has made significant contributions to the transportation sector, relies heavily on nonrenewable fossil fuels that are causing substantial pollution, leading to the industry's unsustainability. To address this issue, the industry has shifted its focus towards sustainable aviation fuels, with hydrogen fuel showing great promise due to its clean and eco-friendly nature. However, the adoption of hydrogen as an energy carrier in aviation presents several challenges, including the lack of a supply chain comparable to that of kerosene, which is currently the primary fuel used in aviation. The supply chain for hydrogen involves various sub-sections such as production, liquefaction, transport, storage, and distribution. This study aims to analyze the hydrogen supply chains for airports and to develop scenarios for its implementation. The study evaluates the environmental impact, cost, sustainability, viability, and safety in different supply chain scenarios, as well as recommending a comprehensive approach to supply chain development that involves collaboration between industry, government, and academia.
