Aviation pioneer Bertrand Piccard, famous for Solar Impulse, has embarked on a new green mission with Climate Impulse in Les Sables d'Olonne, France. The project aims to showcase the potential of green hydrogen by flying a two-seater plane around the globe nonstop over nine days, fueled by hydrogen obtained through electrolysis. Despite the technological advancements, experts believe green hydrogen-powered commercial flights may still be decades away. The project faces challenges such as maintaining efficient hydrogen consumption and ensuring safety due to hydrogen's flammability. Airbus sees hydrogen as a key element in achieving low-carbon commercial planes by 2035, potentially cutting aviation emissions by half. Despite the hurdles, Piccard's pioneering spirit drives the team forward as they work towards a sustainable aviation future.
