H2Fly has successfully filled and tested on the ground a liquid hydrogen tank for use in its HY4 aircraft. The Stuttgart, Germany-based company is developing hydrogen fuel cell-based powertrains for use in aircraft and has been flying HY4 with pressurized gaseous hydrogen since 2016. HY4 is a four-seat aircraft based on the Pipistrel Taurus G4. H2Fly expects the use of liquid hydrogen, which is more challenging to handle and store than gaseous hydrogen, to at least double the HY4's range from 450 to 900 miles (725 to 1,450km). The integration of a liquid hydrogen tank into an aircraft and the successful filling tests is a significant milestone for the program and a world first according to HY4. The liquid hydrogen storage system was designed and supplied by Air Liquide.
