Bertrand Piccard, known for Solar Impulse, is now leading the Climate Impulse project in Les Sables d'Olonne, France, aiming to revolutionize commercial flight with green hydrogen. By splitting hydrogen from water using electrolysis, the team plans to fly a two-seater plane around the globe nonstop over nine days in 2028. The project, backed by Airbus and Solvay's science incubator, is progressing with the construction of the plane's components and testing of fuel cells and propulsion systems. Liquid hydrogen, stored in ultra-insulated tanks, will power the aircraft by seeping into a fuel cell, offering a clean energy alternative with only water vapor emissions. Despite the challenges of maintaining extreme temperatures and ensuring efficient hydrogen consumption, experts believe in the potential of green hydrogen for aviation, though widespread adoption may take decades. The project faces obstacles in scaling up liquid hydrogen production and ensuring safety, as any leaks could lead to catastrophic consequences. While the prospects for green hydrogen in flight are promising, especially in reducing carbon emissions from air travel, the development and implementation of this technology will require significant advancements and investments in the aviation industry.
