A memorandum of understanding (MoU) has been established between Loganair and ZeroAvia to develop zero-emission flights in the UK using hydrogen-electric engines, specifically focusing on integrating ZeroAvia's ZA600 engine into Loganair's regional flights in Scotland. These engines utilize hydrogen fuel cells to produce electricity for electric motors, resulting in only pure water emissions. The partnership will start with certifying the ZA600 in smaller aircraft like the Cessna Caravan and later expand to include larger planes like the Twin Otter and ATR family of aircraft. This collaboration is significant as Loganair is Scotland's largest regional airline, potentially impacting flights in Scotland and Northeast England. ZeroAvia's LH-SIFT project, funded by the UK government, aims to develop a liquid hydrogen management system for aircraft, with a focus on creating a lightweight tank for hydrogen storage. This project will culminate in the testing of a modified Dornier 228 aircraft powered by liquid hydrogen, a pioneering achievement in the aviation industry. The joint efforts of Loganair and ZeroAvia are expected to bring about cleaner and more sustainable air travel options for passengers in the region.
