Startup behind world’s first hydrogen eVTOL eyes 2025 takeoff

Swiss startup Sirius Aviation has unveiled designs for the world’s first hydrogen-electric vertical takeoff and landing (eVTOL) aircraft. 

The jet, which kind of looks like Night Fury from How to Train Your Dragon, is billed to travel 1,851 km at speeds up to 520 km/h. That is four times as far as competitors like  German eVTOL startup Lilium are targeting using batteries.

It will achieve these feats thanks to liquid hydrogen propulsion, which some consider the holy grail of fuels. The energy density of liquid hydrogen means vehicles can travel much further than when powered by gaseous hydrogen or batteries — without an increase in weight.
