Hydrogen fuel is poised to transform not only flights but also airport operations, particularly Ground Support Equipment (GSE). Bristol Airport's public affairs manager, James Cox, foresees two phases in hydrogen aviation: smaller regional aircraft using gaseous hydrogen in this decade, with larger airliners shifting to liquid hydrogen by the mid-2030s. Infrastructure challenges include storage, with gaseous hydrogen initially, and later transitioning to liquid hydrogen. Project Acorn showcased safe hydrogen refueling at Bristol Airport, emphasizing the need for industry-wide standards. Bristol Airport's involvement in Hydrogen in Aviation and Hydrogen South West highlights collaborative efforts to advance hydrogen-powered flight. Other players like Jacobs and Glasgow Airport are also actively driving the adoption of hydrogen aviation. However, challenges persist, including the 'chicken and egg' issue of supply and demand. Overall, the article reflects a positive sentiment towards hydrogen's pivotal role in decarbonizing aviation and the concerted efforts to overcome associated challenges.
