Electrive reports that Dovetail will use two hydrogen fuel cell propulsion systems from Hyundai's HTWO subsidiary, which if proven worthy, will be installed in its Iron Bird aircraft for potential flight testing. Dovetail engineers already tested an electric motor with a power of 250 kW for the said aircraft, including all the electronic components and the control systems. With the electric motor now chosen, the company needs to secure the right fuel cell system, which will provide the required power.

Should the electric motor system work well with the fuel cell solution, further testing will be advanced and the maiden flight could take place sometime in 2024.

Being one of Australia's largest regional and domestic airline company, Rex Group acquired 20% of Dovetail Electric Aviation, thus looking to move from kerosene-powered aircraft to fully electric models in the future.

David Doral, CEO of Dovetail Electric Aviation, said that "Dovetail Electric Aviation looks forward to working with HTWO, a global leader in hydrogen fuel cell technology. This opportunity will enable us to combine our expertise in aviation with HTWO’s expertise in fuel cell technology to develop innovative solutions for a sustainable future in aviation."

Despite being made initially for future Hyundai EVs, the company's fuel cell propulsion systems can be adapted for other use cases, as well, such as Iveco's electric buses and even clean-powered aircraft. Dovetail Electric Aviation is a clean flying startup with a presence not only in Australia, but also in Spain.
