Loganair, the UK's largest regional airline, is pushing forward in sustainable aviation with hydrogen-fuelled flights. Partnering with Heart Aerospace, Loganair is exploring hydrogen infrastructure deployment in Scotland, focusing on short-haul routes from Orkney. The collaboration involves key organizations to test and establish the required infrastructure for long-term operation of hydrogen-fuelled services. Loganair's commitment to innovation is evident through its efforts in sustainable flight initiatives. The aim is to launch the world's first hydrogen-powered commercial flight by 2030, setting a milestone for the industry. The UK Civil Aviation Authority's role in these trials emphasizes the country's ambition to lead in hydrogen propulsion technology. Together with industry partners, Loganair and other stakeholders are driving towards a more sustainable aerospace system, contributing to economic growth and environmental preservation.
