H2FLY has successfully passed the filling tests of the new liquid hydrogen storage system that is designed and supplied by its project partner Air Liquide based on H2FLY’s requirements. The filling procedure took place in preparation for the forthcoming coupling tests in which the liquid hydrogen storage system will be coupled with the fuel cell system to form a complete hydrogen-electric powertrain. H2FLY led the test campaign on Air Liquide’s Campus Technologies Grenoble, in Sassenage, France, together with Air Liquide.
By reaching this milestone, the consortium demonstrates world-leading experience in liquid hydrogen refuelling operations and liquid hydrogen handling on board of an aircraft. Prof. Dr. Josef Kallo, co-founder and CEO of H2FLY, says: “The successful on-ground filling tests today, mark the next milestone in our pursuit to doubling the range of our HY4 aircraft. It is a critical step for our upcoming flight test campaign this summer, which will demonstrate the feasibility of liquid hydrogen as a fuel for medium and long-haul flight.”
This filling milestone follows the company’s announcement in November 2022 that it had started the mechanical integration of Air Liquide’s liquid hydrogen tank into H2FLY’s fuel cell powered aircraft HY4 after the tank passed the vibration and LH2 leakage tests in September 2022.
