Where innovation
takes flight.
(Ascendance)
We’re taking aviation to new heights.
Join us on our journey to more sustainable aviation !
As the world grapples with the effects of climate change, we must all, collectively, act now. The good news is, we have the solution to make a difference and have a positive impact : hybrid electric technology.
It’s not just a trend. It is, and will be, the most sustainable way to decarbonize air transport. Welcome on board the long haul flight to cleaner connections.
(Our technology)
Decarbonizing air transport with hybrid electric propulsion technology and sustainable aircraft.
High performance solutions to drive progress forward
Our technology has the potential to enable and boost the energy transition in aviation to reach carbon neutrality by 2050
Lead the environmental charge with reduced noise, reduced CO2 emissions and reduced costs.
