By the end of the decade, Europe may witness the launch of the world’s first certified commercial business jet powered by hydrogen. French startup Beyond Aero is spearheading this innovation, as its BYA-1 aircraft is set to revolutionize the aviation industry. Since its inception in 2020, Beyond Aero has made remarkable progress, refining its hydrogen-electric jet concept and securing strong industry support. Now, it is moving toward certification from the European Union Aviation Safety Agency (EASA).
A Vision for Hydrogen-Powered Business Aviation
Beyond Aero, which operates out of Toulouse, Paris, and Los Angeles, first introduced its hydrogen-electric jet concept in France just two years ago. Since then, the design has been optimized to improve efficiency and performance.
The BYA-1 is a six-passenger aircraft with a projected range of 800 nautical miles (1,500 km). This makes it well-suited for most business and leisure travel routes across Europe. Most traditional electric jets are limited by battery technology but, the BYA-1 can overcome this problem offers up to five times the range. Additionally, hydrogen propulsion makes this jet more cost-effective compared to sustainable aviation fuel (SAF) and conventional Jet A-1 fuel.
This innovative hydrogen-powered aircraft could enable non-stop flights between key destinations such as London and Nice, all while producing zero direct CO₂ emissions. Thanks to fuel cell technology, it promises both environmental benefits and operational efficiency.
Overcoming the Challenges of Hydrogen Propulsion
Developing a hydrogen-powered jet presents unique challenges, particularly in terms of aircraft architecture. Beyond Aero recently unveiled an optimized version of the BYA-1, incorporating key improvements for better safety and performance.
The aircraft is installed a modular twin-electric-engine system, with independent power channels ensuring redundancy and Its hydrogen tanks, pressurized to 700 bar, are positioned above the wing box structure to minimize risks and enhance safety.
Additionally, the fuel cell stack’s capacity has been increased to 2.4 MW, further boosting efficiency.
Apart from its environmental benefits, the BYA-1 is also designed to reduce operating costs. With an all-electric powertrain that has 90% fewer moving parts than traditional jets, maintenance expenses are expected to be significantly lower. Meanwhile, hydrogen fuel costs are projected to decrease over time, making this jet even more financially viable for operators.
A Premium Passenger Experience
Beyond its technical advancements, the BYA-1 also prioritizes passenger comfort. It features larger elliptical windows—almost 30% bigger than those on conventional business jets—providing an enhanced in-flight experience. Advanced noise insulation technology allows both the passengers and crew to communicate without the use of headsets, plus the onboard Starlink high-speed Wi-Fi ensures seamless connectivity.
Paving the Way for Hydrogen Aviation Regulations
Beyond Aero’s groundbreaking work is also influencing regulatory frameworks. The startup is collaborating with EASA to establish certification standards for hydrogen-powered aircraft. While the BYA-1 follows the general light jet architecture under EASA CS-23 regulations, its hydrogen propulsion system introduces new considerations that require updated guidelines.
With both the expertise and financial backing to push forward, Beyond Aero aims to have the BYA-1 ready for takeoff by 2030. If successful, this hydrogen-electric business jet could mark a major milestone in sustainable aviation, which could set a new standard for eco-friendly air travel.
