Does the idea of swapping the Continental in your Bonanza for a hydrogen-electric propulsion set-up interest you?
If so, you might want to take a look at Stralis.
Founded in Australia in 2021, Stralis seeks to decarbonize aviation. To achieve this goal, Stralis is developing hydrogen-electric propulsion (HEP) systems it claims can fly 10 times farther than battery-electric alternatives and operate at 50% lower costs compared to fossil fuel-powered aircraft.
The company is working on a trio of initiatives: Retrofitting a Beech A36 Bonanza and a Beech 1900D while also developing the clean sheet SA-1, a 50-seat twin-motor aircraft.
Stralis currently has two A36 Bonanza airframes. The pair of A36-HEs are affectionally named Bonnie and Clyde. Clyde, the ground-based test bed, ran the HEP system in December 2024 at Brisbane International Airport. The goal for Bonnie is to fly her, HEP-powered, in the third quarter of 2025.
The company is seeking expressions of interest from the Bonanza community.
