Aviation pioneer Bertrand Piccard, known for Solar Impulse, is now leading the Climate Impulse project to transform air travel using super-cooled liquid hydrogen. The aim is to fly a two-seater plane nonstop around the world over nine days fueled by green hydrogen produced through electrolysis. The project, backed by Airbus and Solvay's Syensqo, presented its progress in Les Sables d'Olonne. While the ambitious journey is set for 2028, initial test flights are planned for 2023 to validate the innovative technology. The project faces challenges in scaling up green hydrogen for aviation, but experts see its potential in significantly reducing carbon emissions. The Climate Impulse team has made strides in building the plane, focusing on crucial components like fuel cells and propulsion systems. Liquid hydrogen's use poses challenges due to its extreme cold temperature and flammability, requiring precise engineering. Despite hurdles, the project signifies a bold step towards sustainable and eco-friendly air travel, aiming to inspire the industry to embrace cleaner energy solutions.
