Loganair, the UK's largest regional airline, is making significant strides towards sustainable regional flights by delving into hydrogen infrastructure in Scotland. In partnership with various organizations, Loganair is using Orkney's Kirkwall Airport as a testing ground to explore the rollout of hydrogen fuel infrastructure across the region. The airline has identified suitable short-haul routes for hydrogen-fueled services and is progressing to test the necessary infrastructure for long-term operations. Additionally, Loganair is actively engaged in other sustainable flight initiatives, such as partnering with Heart Aerospace on hybrid-electric aircraft and meeting the Sustainable Aviation Fuel (SAF) mandate. The company believes in keeping multiple sustainability options open, with the hydrogen challenge being a crucial part of their portfolio. Rebecca Borresen, Director of Safety and Sustainability at Loganair, emphasizes the company's leadership in sustainable aviation and their ambition to achieve the world's first hydrogen-powered commercial flight by 2030. The UK Civil Aviation Authority and stakeholders like HITRANS are optimistic about the potential of hydrogen propulsion in the aerospace sector, foreseeing a more sustainable aviation system and economic growth. Jayne Golding from HITRANS highlights the significant opportunity that hydrogen fuel presents for the aviation industry, particularly in reducing air transport emissions. Overall, the collaborative efforts in Scotland aim to pave the way for a more sustainable and innovative future in regional aviation.
