ZeroAvia has bought two twin-engine, 19-seat Dornier 228 aircraft to retrofit with its biggest hydrogen powertrain to date (Digitally altered image)ZeroAviaVIEW 1 IMAGESDespite an abrupt and unscheduled ending to its six-seater test program, hydrogen aviation pioneer ZeroAvia is ramping up development of the largest fuel-cell-powered aircraft to date – a pair of 19-seaters – and is preparing for something much bigger.Moving toward zero carbon emissions will prove particularly difficult for some industries. Long-haul aviation has given us global mobility on the back of the enormous energy density offered by fossil fuels. Batteries won't be much use; at around 260 Wh/kg, they trail a long way behind jet fuel at around 12,000 Wh/kg, even when the inefficiencies of combustion engines are taken into account.MORE STORIESAUTOMOTIVEVanderhall's big-tired 404-hp electric buggy explodes through the sandBICYCLESMV Agusta motors into electric mobility space with Amo ebikesHydrogen, on the other hand, stores around a whopping 33,600 Wh/kg of usable energy, making it one of the most energy-dense fuels by weight and offering genuine potential as an aviation power source, even when the inefficiencies of fuel cell powertrains and the high weight and space penalties for hydrogen storage tanks are taken into account.
