H2FLY enables liquid hydrogen storage coupled to fuel cell systems

Germany-based H2FLY announced on April 28 that it has successfully combined its liquid hydrogen storage system with the fuel cell system on its HY4 aircraft.

As part of the HEAVEN project, which focuses on the design, development and integration of fuel cells and cryogenic power systems for commercial aircraft, the test was conducted in collaboration with project partner Air Liquefaction at its Campus Technologies Grenoble facility in Sassenage, France.

Combining the liquid hydrogen storage system with the fuel cell system is the "final" technical building block in the development of the HY4 aircraft's hydrogen electric power system, which will allow the company to extend its technology to 40-seater aircraft.

H2FLY said the test made it the first company to successfully conduct ground coupled testing of an aircraft's integrated liquid hydrogen tank and fuel cell system, demonstrating that its design complies with the requirements of the European Aviation Safety Agency (EASA) for CS-23 and CS-25 aircraft.

"With the success of the ground coupling test, we have learned that it is possible to extend our technology to 40-seat aircraft," said H2FLY co-founder and CEO Professor Dr. Josef Kallo. "We are pleased to have made this important advance as we continue our efforts to achieve sustainable medium - and long-haul flights."

Just a few weeks ago, the company announced that it had passed the first filling test of its liquid hydrogen tank.

H2FLY hopes liquid hydrogen tanks will double the range of an aircraft.
