The promise of a sustainable aviation future is coming to fruition with Sirius Aviation AG's new liquid hydrogen eVTOL. Offering impressive autonomy, this Swiss project could redefine air travel.
The future of aviation is moving towards hydrogen as an ecological alternative to fossil fuels. Airbus, a pioneer in this field, announced the development of commercial hydrogen aircraft planned for 2035. At the same time, Rolls-Royce and EasyJet took a new step with the first hydrogen aircraft engine, paving the way for more ecological and efficient flights.
Aviation innovation doesn't stop there, with manufacturers replacing conventional jet engines by electric motors. This is the case of a plane equipped with 3600 kg of batteries, proving the effectiveness of electricity. In this context where the entire aeronautical sector is looking for solutions to reduce its carbon footprint, Sirius Aviation AG launches the Sirius Jet, based on an astonishing system, offering better efficiency and increased autonomy.
This hydrogen plane has a range of 1,850 km
The aerodynamic configuration of the Sirius Jet is definitely modern. The double wings, equipped with multiple electric fans mounted inside ducts, optimize the transition between vertical takeoff and horizontal flight. The extended fuselage and wide canopy are designed to maximize fuel efficiency and reduce wind resistance, while increasing internal space for passengers.
According to the manufacturer, each element of the device has been developed with a “concern for efficiency and performance“. Advanced composite materials reduce overall weight, while liquid hydrogen propulsion offers higher energy density than battery-based solutions. This allows the Sirius Jet to reach a cruising speed of 520 km/h with a record range of 1,850 km. And, beyond its futuristic silhouette, the design of this aircraft is focused on sustainable innovation. Liquid hydrogen, which powers the device's electric motors, is stored at extremely low temperatures to maintain its liquid state where it fuels most efficiently.
With its eVTOL, Sirius Aviation AG is not just creating a clean aircraft. The latter is accompanied of a complete ecosystem. This includes hydrogen refueling infrastructure and new generation navigation systems. The first demonstration of this aircraft is planned for 2025 with, in sight, a commercial entry into service in 2028.
