California-based firm HyPoint is developing an innovative cryogenic tank design that could massively boost the range of hydrogen-powered aircraft, a press statement reveals. HyPoint's technology is extremely lightweight compared with traditional fuel cells and it could allow airliners to fly up to four times farther than traditional passenger aircraft. A 50-56 passenger De Havilland Canada Dash-8 Q300, for example, can fly approximately 1,558 km (968 miles) on jet fuel, according to HyPoint. If it were retrofitted with a fuel cell powertrain and a GTL composite tank, it would be able to fly as far as 4,488 km (2,789 miles).
