Zero Avia, a hydrogen-electric aircraft developer, has partnered with Hamburg Airport, Rotterdam The Hague Airport, and urban aviation clusters to promote climate-neutral airport operations. A 'Memorandum of Understanding' has been signed to conduct the first hydrogen flight between Hamburg and Rotterdam by 2026. Work is ongoing to establish a hydrogen flight route and necessary infrastructure. The collaboration involves setting up a mobile hydrogen refueling system at the airports and ensuring compliance with safety regulations. Hamburg Airport is actively engaging in sustainable aviation initiatives, including the 'Hydrogen Hub at Airports' network with Airbus. Research projects like the 'Hydrogen Aviation Lab' are exploring the use of liquid hydrogen as an environmentally friendly alternative to traditional fuels. The airport is working closely with partners like the German Aerospace Centre and Lufthansa Technik to advance hydrogen technology in aviation. Hamburg Airport's efforts aim to lead the way in sustainable aviation practices and promote the adoption of hydrogen as a cleaner fuel source in the industry.
