In Les Sables d'Olonne, France, aviation pioneer Bertrand Piccard, previously known for Solar Impulse, is now leading the Climate Impulse project to revolutionize commercial air travel by utilizing super-cooled liquid hydrogen. This green initiative aims to fly a two-seater plane around the globe nonstop fueled by green hydrogen obtained through electrolysis. Despite challenges such as untested innovations and scalability for commercial use, the project has attracted significant investments and support from key players like Airbus and Syensqo. The team plans test flights next year and a round-the-world trip in 2028. The Climate Impulse plane, made with lightweight composites, is designed to fly around Earth at a gentle speed without mid-air refueling, powered by liquid hydrogen that evaporates into a gas to fuel a fuel cell. While the environmental impact of water vapor emissions from this technology remains unclear, experts view green hydrogen as a promising alternative to traditional carbon-based aviation fuels. Liquid hydrogen, maintained at extremely low temperatures, poses challenges in efficient consumption and safety, requiring leak-proof tanks. With Airbus and other aviation experts citing hydrogen as a key pathway to reducing carbon emissions from flights, the Climate Impulse project represents a significant step towards cleaner aviation practices. The potential of liquid hydrogen to revolutionize air travel and significantly cut carbon dioxide emissions has garnered positive attention, positioning the project as a crucial development in sustainable aviation technology.
