H2Fly is stepping up its bid to win the race to power larger regional airliners with hydrogen after announcing plans for a new family of fuel cell systems that can operate at altitudes of up to 27,000 feet. The German company said the H175 technology will be scalable for a variety of hydrogen-electric aircraft in the 1-MW class and seating between 20 and 80 passengers.

According to H2Fly, the new propulsion systems will represent a significant step up in performance compared with hydrogen fuel cell demonstrator aircraft flown to date. The company aims to conduct its first flight demonstrations later this year with its own testbed as it works toward readying the new propulsion system for commercial service in 2027.
