Swiss startup unveils the world’s first hydrogen VTOL jet
Swiss startup Sirius Aviation has unveiled what it says is the world’s first hydrogen VTOL (vertical take off and landing) aircraft — and an ambitious plan to have it in the air by 2025.
The challenge: Electric VTOLs (eVTOLs) are widely promoted as the next big thing in aviation, and dozens of companies developing their own versions of the vehicles — fleets of flying electric taxis planned to zip around cities and over traffic jams.
Like helicopters, eVTOLs can lift off and land without a runway, which means they can operate without airports or runways.
Unlike helicopters, eVTOLs are powered by electricity — this makes them quieter and more climate friendly, but the weight and limited energy density of their batteries means they also can’t fly as far.
