Bertrand Piccard, known for Solar Impulse, is now leading the Climate Impulse project in Les Sables d'Olonne, France, with the goal of revolutionizing air travel using super-cooled liquid hydrogen split from water molecules. The project aims for a nonstop global flight in 2028, presenting a mix of new technologies and untested innovations. Challenges include scalability for commercial use, potential environmental impact of water vapor emissions, and the need to scale up green hydrogen production. Progress includes constructing the cockpit shell, wing spar, and interior components, with upcoming tests on fuel cells and propulsion systems. The project faces technical hurdles, such as regulating liquid hydrogen flow and ensuring tank safety due to the extreme cold temperature and flammability of the fuel. While green hydrogen holds promise for reducing carbon emissions in aviation, challenges in production and infrastructure remain. Airbus sees hydrogen as a key element in low-carbon planes by 2035, highlighting its potential to cut carbon dioxide emissions. Despite hurdles, the project aims to pave the way for a greener and more sustainable future in aviation.
