H2FLY hydrogen aircraft project successfully passes liquid hydrogen refueling test

The German H2FLY project, which is developing hydrogen fuel cells for aircraft, has successfully completed a ground test filling a newly developed hydrogen tank. The project is part of the European HEAVEN consortium, which aims to demonstrate the potential of using hydrogen in aviation.

The successful completion of the filling procedures took place as part of preparations for the future development and connection of the liquid hydrogen tank to the fuel cell system. Together, they form a complete hydrogen-electric propulsion system for the aircraft.

With this milestone, the consortium demonstrated its leading expertise in refueling and handling liquid hydrogen stored on board an aircraft.

According to Prof. Dr. Josef Kallo, co-founder and CEO of H2FLY, this achievement represents: “ …another milestone in our efforts to double the range of our HY4 aircraft. This is a turning point ahead of the summer test campaigns, which will demonstrate the feasibility of using liquid hydrogen as a fuel for medium- and long-haul flights.”
