Creating world-class aircraft manufacturing and passenger experience with decarbonised travel.

Stralis was founded on a singular idea—to be the world's leading emission-free aircraft company producing high-performance, low-operating cost, hydrogen-electric aircraft at scale. We see green hydrogen as a fundamentally clean, carbon-free, lightweight, and economical solution.

Our team has worked on leading electric aircraft programs worldwide. Based on our practical experience with the alternatives, Stralis concludes that hydrogen-electric propulsion is the most commercially viable, and truly sustainable technology. We have come together to deliver what we believe will be the solution.

“Bonnie”, our Bonanza A36-HE technology demonstrator, will take flight in 2025.

Our first solution to the urgent need to decarbonise will be to retrofit existing aircraft with our novel hydrogen-electric propulsion system, allowing us to accelerate the transition to sustainable flight.

Our Bonanza A36-HE technology demonstrator, will take flight in 2025. The program learnings will inform our 15-seat B1900D-HE retrofit, which has an 800km range and enters service late 2026 with our launch customer, Skytrans Airlines.
