Ryze, a clean fuel supplier, has joined forces with ZeroAvia, a zero-emission aviation company, to supply hydrogen for use at Cotswold Airport in Cirencester, UK. Over the past 18 months, ZeroAvia has been conducting flight testing of prototypes, including a 19-seat testbed aircraft, and has developed a Hydrogen Airport Refuelling Ecosystem at the site. The partnership includes a hydrogen supply contract with Ryze to ensure regular deliveries to support ZeroAvia's testing and certification efforts. Ryze's tube trailer fleet, the largest in the UK, will provide flexibility for ZeroAvia's research needs. Sergey Kiselev, chief business officer at ZeroAvia, highlighted the importance of cost-effective, clean hydrogen in achieving zero-emission flight goals. ZeroAvia's team, with over 300 employees, is dedicated to hydrogen-electric propulsion solutions for various markets, aiming to achieve a 300-mile range in smaller aircraft within the next couple of years and up to a 700-mile range in larger aircraft by 2027. The article also mentions the environmental impact of aviation emissions, with over 6.7 million flights from European airports in 2023 emitting a significant amount of CO2. This partnership underscores the commitment to decarbonize aviation and advance sustainable energy solutions in the industry.
