The Swiss company proposes this hydrogen-fueled, zero-emission light passenger aircraft, designed to take off and land vertically, in order to reshape business aviation.
Technology Designer has been reporting on VTOL (vertical take off and landing) vehicles for over six years and as we approach full commercialisation of this innovative transportation, another of our long-term passions – hydrogen-based alternative energy sources – come together in the new Sirius Business Jet.
The proposed Sirius Jet marks a major aviation world first. A vertical take-off and landing (VTOL) aircraft pitched at the business community, the Sirius Business Jet features a pioneering hydrogen-fuelled powerplant. In theory, this makes it a zero-emission solution for regional business trips, with a projected range of 1,850km at speeds of up to 600km/h. It’s pitched alongside the larger Sirius Millennium Jet, and the two craft are still a long way from production.
That’s because hydrogen-powered flight is still very much in its infancy. Sirius’ own Hydrogen-Electric Ducted Fan Propulsion System is due for commercialisation late in 2025. The system uses hydrogen in a fuel cell to produce electricity, rather than as a combustible fuel. There are plenty of prototypes in development around the world, including concepts from Boeing and Airbus, but mass take-up of the technology isn’t expected until the 2030s. Stay tuned.
