Bertrand Piccard, renowned for his solar-powered flight around the world, is now spearheading the Climate Impulse project in France. The project aims to showcase the feasibility of green hydrogen-powered flight by flying a two-seater plane nonstop around the globe over nine days. The initiative, backed by industry giants like Airbus and Solvay, uses liquid hydrogen split from water molecules using renewable electricity. While the project faces technical challenges and requires untested innovations, it has attracted significant investment and is set for test flights next year. If successful, the project could pave the way for greener commercial aviation, but experts warn that widespread implementation is still far off due to scalability issues and the need for more clean electricity production. The project's progress includes building the plane's cockpit and wing spar, with upcoming tests on fuel cells and propulsion systems. Maintaining liquid hydrogen at minus 253 degrees Celsius poses a significant challenge, as any leaks could be extremely dangerous. Despite the hurdles, Airbus sees hydrogen as a crucial element in reducing aviation emissions, with potential to halve carbon dioxide output. While challenges remain, the Climate Impulse project represents a significant step towards cleaner air travel and could lead to a transformative 'Tesla moment' in aviation.
