Our tech will change aviation as we know it.
We are on a mission to become a Tier 1 engine OEM, designing, building, and certifying hydrogen fuel cell powertrains -- pioneering aviation once again. Our cutting-edge propulsion technology is engineered to enable zero-emission regional passenger and cargo flights at the turn of the decade.
Engineering Hydrogen- Powered Aviation
Our 2.1 MW powertrains will first power a series of retrofit Dash 8-300 aircraft, demonstrating the real-world advantages of hydrogen-electric propulsion. With liquid hydrogen storage, our system fully leverages hydrogen’s high energy density to maximize efficiency and range.
Powered and supported by our robust government backed eco-system.
With an investment of €80MM from the Dutch Government, we’ve assembled a dream team of experts, companies, and institutes with proven track records - bringing the capability, credibility, and scale needed to firmly position ourselves in the aerospace market.
A retrofit solution.
Integrating our powertrains into existing aircraft accelerates the transition to sustainable aviation without having to wait for clean-sheet designs. This first deployment lays the groundwork for scaling our technology to other platforms and future forward-fit programs.

How do we change aviation?
The team building the dream.
