Where innovation
takes flight.
(Ascendance)
We’re taking aviation to new heights.
Join us on our journey to cleaner aviation — and become a pioneer of tomorrow’s flight!
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.
At Ascendance, we believe this transformation needs pioneers: bold actors ready to embrace innovation and shape the future of aviation. That’s why we offer three innovative solutions to hybridize all types of aerial vehicles and to unlock the energy transition for you.
