Bertrand Piccard, the Swiss adventurer behind Solar Impulse, is now focusing on Climate Impulse, a project aiming to revolutionize air travel by using green hydrogen as a power source. The Climate Impulse team presented its progress in Les Sables d'Olonne, detailing plans to fly a two-seater plane around the globe nonstop over nine days fueled by green hydrogen produced through electrolysis. The project, backed by Airbus and other partners, faces challenges such as untested innovations and the need for efficient liquid hydrogen consumption. Despite these hurdles, the team aims to demonstrate the feasibility of hydrogen-powered long-haul flights. If successful, the project could significantly reduce carbon dioxide emissions in aviation. While the widespread adoption of green hydrogen in aviation may be years away, the Climate Impulse project represents a crucial step towards cleaner and more sustainable air travel.
