Loganair, the UK's largest regional airline, is making significant strides in sustainability by aiming to introduce the world's first commercial hydrogen-fuel aircraft route. Through a partnership involving various organizations, Loganair is exploring the implementation of hydrogen infrastructure across Scotland, with a specific focus on Orkney. The UK Civil Aviation Authority has launched the second phase of the 'Hydrogen Challenge,' with Loganair leading the way in progressing hydrogen fuel operations from its Orkney base. The airline is actively involved in Sustainable Aviation Test Environment (SATE) projects, partnering with key organizations to test the necessary infrastructure for hydrogen-fueled services. Loganair's commitment to sustainable aviation extends beyond hydrogen, including initiatives like hybrid-electric aircraft and meeting SAF mandates. The airline aims to achieve the milestone of the first hydrogen-powered commercial flight before 2030. This initiative has received positive support from industry leaders and officials, recognizing the potential of hydrogen propulsion for a more sustainable aerospace system and economic growth in the UK.
