NASA's Glenn Research Center has issued a Request for Information (RFI) on hydrogen aviation programs, hinting at the development of a cryogenic hydrogen test facility. This facility aims to advance research in aeronautics, specifically focusing on the use of hydrogen as a fuel source for aviation. Concurrently, French partners are making strides in testing a liquid hydrogen turbine engine for general aviation, furthering the progress of hydrogen propulsion in the industry. The sentiment towards hydrogen in the article is positive, with a focus on sustainable aviation fuel (SAF) and the need for urgent investment in eSAF. Industry campaigns like 'Climbing Fast' are driving sustainability initiatives and forming transatlantic partnerships to promote the adoption of biofuels in aviation. Additionally, World Fuel and DHL have collaborated to bring regular deliveries of SAF to Miami, marking a significant step towards reducing the carbon footprint of the aviation industry.
