Beyond Aero, a French aerospace startup, has completed the Preliminary Design Review for its BYA-I One, a hydrogen private jet aiming for zero-emission regional flights by 2030.
Hydrogen private jet: zero emissions from French startup Beyond Aero
A zero-emission hydrogen private jet, aimed at helping air mobility reduce its polluting impact. This prototype is being developed by the French aerospace startup Beyond Aero, which announced the completion of the Preliminary Design Review for its BYA-I One aircraft. The goal is to replace gas turbines with hydrogen-powered fuel cells, thereby reducing environmental and noise pollution.
What changes with pressurized hydrogen
One of the main challenges for hydrogen aviation is the fuel’s energy density. This means a large amount of hydrogen is needed to achieve the same results as traditional fuel; while many aerospace competitors focus on liquid hydrogen – which requires cryogenic temperatures and complex infrastructure – Beyond Aero will use gaseous hydrogen pressurized to 700 atmospheres.
Less pollution and less noise, but another issue remains: weight. Approximately 20 kg of carbon fiber tanks are needed to store 1 kg of hydrogen; the external tanks are designed to be integrated above the wing structure and have natural ventilation. Furthermore, gaseous hydrogen can be stored without thermal losses, and 700 bar refueling stations are already a commercial reality (used, for example, by the Toyota Mirai).
Performance of the hydrogen private jet
The BYA-I One is designed to serve regional routes and short distances, with a flight range of approximately 1,482 km and a cruise speed of 300 knots. It can accommodate up to eight passengers and two crew members. Its technological core consists of six 400 kW fuel cells, which power electric turbofan engines.
Towards 2030 for certification
According to Chief Engineer Luiz Oliveira, the current configuration has reached the necessary maturity to support a certifiable architecture at the European level by the responsible authority, EASA. If the roadmap is followed, entry into service in 2030 will allow future owners to operate carbon-free flights.
