Dovetail Electric Aviation has received a financial boost from the Spanish state to advance its efforts in developing an electric powertrain with a focus on hydrogen-electric propulsion technologies for next-generation aircraft. Partnering with Aciturri and ITP Aero on a €5.6 million initiative, the project aims to integrate a hydrogen-electric powertrain conversion for a CS-23-category aircraft, utilizing Dovetail's battery pack and electric propulsion system. Ground tests using a Cessna Caravan airframe are set to commence in the summer, with the goal of having a flight-ready aircraft by late 2025 and conducting its maiden flight in early 2026. Dovetail plans to implement upgraded versions of its electric propulsion system in both ground-test and flight-test aircraft, potentially focusing on the De Havilland Canada DHC-6 Twin Otter for its second conversion project. Despite the shift in focus, the company remains engaged with operators and is actively pursuing external funding to support its development milestones, including certification flights and a Series A funding round by the end of 2026. Testing of the powertrain will occur in Seville, Spain, with potential plans to move operations to Toulouse, France in the future. The company's CEO, David Doral, expresses optimism about the project's progress and emphasizes the importance of sustainable aviation and decarbonization efforts in the industry.
