When aviation pioneer Bertrand Piccard a decade ago spearheaded a much-hyped flight around the world in a plane powered by sunlight, it raised awareness about climate change but held little promise of revolutionizing air travel.
Now, the 66-year-old Swiss adventurer behind Solar Impulse is aiming higher, in hopes of heading toward greener commercial flight, this time using super-cooled liquid hydrogen.
From a workshop on France’s Atlantic coast, Piccard and his partners are ramping up Climate Impulse, a project started last February to fly a two-seater plane around the globe nonstop over nine days fueled by what’s known as green hydrogen. That’s hydrogen split out of water molecules using renewable electricity through a process called electrolysis.
