Stralis Aircraft conversion of Bonanza A36 aircraft to hydrogen propulsion
By the end of 2025, Stralis Aircraft aims to start flight testing a Bonanza A36 aircraft converted to run on green hydrogen fuel.

Stralis Aircraft is advancing its plans for hydrogen-powered aircraft, starting with a technology demonstrator based on a Bonanza A36 model with which it is aiming to start flight tests by the end of 2025. The Australian start-up intends to apply for a supplemental type certificate (STC) covering the conversion of the single-engined aircraft. It also has longer-term plans to convert the larger Beech 1900D utility aircraft and to develop a clean-sheet regional airliner called the SA-1-HE.

In late March, Brisbane-based Stralis announced a partnership with New Zealand company Fabrum, which will develop and test liquid hydrogen storage tanks and a fuel system for its hydrogen-electric propulsion system. The companies have received support from Ara Ake, which is New Zealand’s future energy center.
