Swiss aviation pioneer Bertrand Piccard is developing a plane powered by liquid hydrogen after a much-hyped flight in 2015 that used sunlight to travel around the world. The new project called Climate Impulse aims to circle the globe in 2028 in a lightweight two-seater that runs on what is known as “green” hydrogen, split from water molecules through electrolysis. It’s ultimately a testbed of technology that big plane makers might use one day. Work is now in a second year but outside experts say scientific challenges await and it won’t be scalable for decades, if at all.
