Swiss explorer and aviator Bertrand Piccard is embarking on a groundbreaking mission to achieve a historic aviation feat by flying non-stop around the world using liquid hydrogen as fuel. Together with co-pilot Raphaël Dinelli, Piccard is preparing for this ambitious journey along the equator, set for 2028 with test flights scheduled for next year. The Climate Impulse project, supported by industry leaders like Airbus and Syensqo, is at the forefront of this revolutionary initiative. The project unveiled its first-year progress in Les Sables d’Olonne, France, showcasing the innovative Climate Impulse aircraft designed for clean aviation. This marvel of engineering boasts a lightweight construction and a hydrogen fuel system that converts liquid hydrogen into electricity, emitting only water vapor. However, challenges such as untested liquid hydrogen use and production scalability remain. Despite these obstacles, the project aims to harness atmospheric energy to enhance fuel efficiency and reduce emissions. The future of hydrogen-powered aviation holds significant promise, with liquid hydrogen offering increased energy density and range. Transitioning to hydrogen could potentially transform air travel sustainability, combating a notable portion of global CO2 emissions from the aviation sector.
