Hydrogen aircraft company Beyond Aero has reached an important design milestone for its hydrogen-electric business jet.
Beyond Aero has completed its Preliminary Design Review (PDR), a key step that confirms the aircraft’s concept is ready to move forward. It is also progressing with certification under CS-25 and Part 25 rules from European and U.S. regulators. This marks real progress as hydrogen aviation moves closer to becoming a practical industry.
Finishing this phase means the aircraft’s main systems, hydrogen storage, electric propulsion, cooling, fuel cells, and safety, have all been successfully integrated into a design that could be certified. The project will now move into detailed design, engineering work, and testing plans.

Hydrogen propulsion setup:
The jet will use two propfans powered by fuel-cell electric systems. It will run on compressed hydrogen stored at very high pressure (700 bar) in tanks mounted above the wings.
This design helps with ventilation and makes it easier to use current and future airport refueling systems. It also avoids the added complexity of using super-cold liquid hydrogen, helping the aircraft enter service sooner.
Wind tunnel tests have already confirmed that the aircraft’s aerodynamic performance matches computer simulations, supporting the design’s accuracy.

Why it matters:
This milestone shows that hydrogen-powered aviation is moving beyond concepts and into real, buildable aircraft. Completing the design review means the technology is no longer just theoretical, it’s being shaped to meet strict safety and certification standards.
It also highlights a practical path to cutting aviation emissions. By using hydrogen fuel cells instead of traditional jet fuel, the aircraft could significantly reduce or even eliminate carbon emissions during flight.

Luiz Oliveira, Chief Engineer at Beyond Aero, said:
“The Preliminary Design Review confirms that the aircraft configuration and its major systems, propulsion, hydrogen storage, aerodynamics and avionics, have reached the level of maturity required to support a certifiable architecture. With this milestone completed, the program moves on schedule into detailed design and verification of the aircraft’s integrated systems.”
