ZeroAvia and Loganair have entered into a promising partnership at the Paris Air Show to work on the adoption of hydrogen-electric engines for zero-emission flights. The agreement aims to pave the way for sustainable aviation practices in the UK, with Loganair expressing enthusiasm for the technology. ZeroAvia was granted funds by the UK government to develop a liquid hydrogen management system for aircraft, with plans to integrate it into a testbed for flight trials. The project, named LH-SIFT, will focus on creating a lightweight fuel system for aircraft engines. ZeroAvia's ZA2000 engine, utilizing liquid hydrogen, is targeted for aircraft like the Cessna Caravan and ATR family, offering greater energy density than gaseous hydrogen. Additionally, ZeroAvia is working on a 600kW hydrogen-electric powertrain for smaller aircraft, aiming for certification with the UK regulator CAA. The partnership also involves establishing a hydrogen fuel cell manufacturing center close to Glasgow Airport, Loganair's base, showcasing a commitment to greener aviation. Both companies are optimistic about the future impact of their collaboration on sustainable air travel and cleaner transport for passengers in Scotland and the UK.
