Next-generation aircraft company Sirius Aviation has unveiled two new models of its hydrogen-powered Sirius Jet, the CEO Jet and the ADVENTURE Jet. 

The Swiss company revealed the designs during an event at MOVE Expo in London and published further details about the small aircraft, after debuting its hydrogen-electric powertrain technology in January. 

The new models have been designed by Sirius and BMW owned Designworks and are described by the company as “not only technologically advanced but also aesthetically stunning.” 

Designed for the business aviation market, Sirius has marketed its aircraft as “bridging the gap” for customers wanting to own a business jet while still making sustainable choices, with its engines emitting only water vapour and no pollutants. 

The proprietary engines weigh 9.6kg each and are designed to deliver a thrust of 100 kilogram-force per engine, working with a hydrogen-electric ducted fan propulsion system. 

The CEO and ADVENTURE aircraft are based on very similar designs but the latter model is designed for more off-grid travel and can be fitted with extra features such as floats to allow for a transition from air to water travel. 

Other amenities announced by Sirius include private pod seating, a panoramic cockpit, touchscreen systems, a Hawkeye camera, searchlights, and dust protected fans to ensure reliability in challenging environments. 

Sirius will be hoping that the launch of the new models will bring further attention to its hydrogen jets, building on its early success with the aircraft including deals in India, where Sirius is working with Mehair to establish final assembly lanes for the Sirius Millenium Jet. 

While the aviation industry is currently focused on more immediate but non-zero environmental solutions, such as sustainable aviation fuel, hydrogen has become one of the most likely solutions for emission-free air travel in the future. 

Alongside start-ups such as Sirius, major companies have also been exploring the tech, with Airbus creating its own hydrogen aircraft and a network of airport hubs around, recently adding George Bush Intercontinental Airport in Texas, US.
