British aviation takes off into the zero-emission era with its first hydrogen-powered regional flights.

Aviation is entering a new era. After decades of emissions that have contributed to climate change, the aerospace sector is seeking clean alternatives that allow for zero-carbon flight. Among the most promising solutions is hydrogen, capable of powering electric motors that turn aircraft into virtually emission-free vehicles.

Among the companies leading this revolution is ZeroAvia, founded in 2017 and based in both the United Kingdom and the United States. Specializing in the development of hydrogen-powered electric engines, the company has focused its efforts on regional aircraft with up to 19 seats. Its goal is to offer a clean, efficient propulsion system capable of operating real, zero-emission commercial flights.

ZeroAvia recently took a historic step by partnering with Scottish regional airline Loganair to launch the world's first zero-emission commercial flights. This collaboration is initially based on the use of its ZA600 system, successfully tested on the Dornier 228 , but for planned commercial flights, the 2,500 kW ZA2000 engine will be deployed, combining sufficient power and range for regional routes for 40- to 80-seat aircraft. The company has already conducted multiple flight tests after obtaining experimental certification for three prototypes.

The heart of this innovation is the 2,500 kW ZA2000 electric engine, specifically designed for regional aircraft. This power output allows aircraft with up to 80 seats to be powered with hydrogen, achieving zero-CO2 emissions and significantly reducing noise compared to traditional engines. Its modular design facilitates adaptation to different aircraft models and extends the lifespan of the propulsion systems, which will undoubtedly become a viable alternative for regional aviation in the near future.

At the same time, it offers a solution capable of offering a range of up to 1,100 kilometers, sufficient to cover most regional routes reliably. From an operational and economic perspective, they also represent an attractive opportunity for Loganair, as electric engines require less maintenance than combustion engines, resulting in greater availability and lower costs.

Aside from these advantages, another notable aspect is the impact on noise and the passenger experience. Electric motors powered by hydrogen fuel cells generate less vibration and less noise than conventional engines, resulting in a quieter flight, especially during takeoff and landing. This not only benefits passengers but also the communities surrounding airports by reducing noise pollution.

The collaboration with Loganair will allow ZeroAvia to test its ZA2000 engine on commercial regional flights, connecting small towns in Scotland with sustainable, zero-emission routes. These flights will serve as a real-world demonstration that hydrogen propulsion, beyond laboratory testing, is also viable in commercial operations.

Project leaders are confident that the flexibility of the ZA2000 system will make it easier for other regional operators to join this transition to greener aviation.
