As soon as thought-about prohibitively costly and inefficient, hydrogen fuel-powered planes are lastly starting to actually and figuratively take off around the globe. Final week, the Germany-based startup H2FLY achieved a serious trade milestone—finishing the world’s first piloted electrical plane flights fueled fully by liquid hydrogen.
“This achievement marks a watershed second in using hydrogen to energy plane. Along with our companions, now we have demonstrated the viability of liquid hydrogen to assist medium and long-range emissions-free flight,” H2FLY co-founder Josef Kallo said in a statement on September 7.
In accordance with the corporate’s official announcement, H2FLY accomplished a complete of 4 flights utilizing liquid hydrogen, considered one of which boasted over three hours of airtime. Not like previous checks, nonetheless, the corporate’s HY4 prototype plane this time round utilized liquified, cryogenically saved hydrogen (LH2) as a substitute of pressurized gaseous hydrogen (GH2). The gas supply alteration reportedly permits for considerably decrease gas tank volumes and weights, thus boosting the plane’s vary, in addition to the quantity of house that may be devoted for payloads.

Even with solely 4 take a look at flights accomplished, LH2 gas reveals unbelievable promise in powering more-sustainable planes. Because of the strategic gas shift, the corporate’s HY4 plane can hypothetically double its most vary from 750 km to 1,500 km (466 to 932 miles), making it far more viable for medium- and long-haul industrial, carbon-emissions free flights. For comparability, a flight from New York Metropolis to Columbus, Ohio, is round 765 km; a flight from NYC to Tallahassee, Florida, is about 1,470 km.
As Electrek notes, H2FLY engineers boast a string of achievements over time when in comparison with comparable zero-emission aviation corporations. The HY4 plane accomplished its maiden flight in 2016, and set new information when it achieved an altitude of over 7,000 throughout a 77-mile take a look at run in 2022.
Atop the spectacular take a look at outcomes, H2FLY explains its newest HY4 flights “marks the end result” of Undertaking HEAVEN, “a European-government-supported consortium assembled to reveal the feasibility of utilizing liquid, cryogenic hydrogen in plane.” Other than varied enterprise consortium companions, the challenge included funding from the German Federal Ministry for Financial Affairs and Local weather Motion, the German Federal Ministry for Digital and Transport, and the College of Ulm.
Shifting ahead, H2FLY goals to start work on commercialization of its plane and gas applied sciences. This can embody the event of latest gas cell programs able to offering full energy ranges for emissionless flights reaching altitudes as excessive as 27,000 toes. Subsequent 12 months, the corporate additionally plans to open a Hydrogen Aviation Heart at Germany’s Stuttgart Airport.
