Bertrand Piccard, known for his Solar Impulse project, is now leading the Climate Impulse initiative to revolutionize commercial flight using super-cold liquid hydrogen generated from green sources. The project, backed by Airbus and Syensqo, aims to fly a two-seater plane around the world nonstop over nine days fueled by green hydrogen. Test flights are planned for the next year, with a full round-the-world trip scheduled for 2028. While the project faces challenges in innovation and scalability, it has attracted significant investment. The plane, made with lightweight composites, will rely on untested technologies and innovations. The controlled release of liquid hydrogen under the wings will power the plane with minimal environmental impact, as it only emits water vapor. Despite the potential of green hydrogen in aviation, experts suggest that its commercial scale implementation may still be decades away. The team has made progress in building the plane's components and interiors, including a unique cockpit design to accommodate co-pilots during the long-haul flight. Challenges remain in regulating the flow of liquid hydrogen and maintaining its extremely low temperatures. Safety concerns regarding the flammability of liquid hydrogen also need to be addressed. The use of super-cold liquid hydrogen in aviation represents a significant technological advancement with the potential to reduce carbon emissions in the industry. While the road ahead is challenging, the Climate Impulse project showcases the possibilities of hydrogen in powering sustainable air travel and driving innovation in the aviation sector.
