The fuel-cell-powered Antares DLR-H2 during its maiden flight on July 7 over Hamburg

On July 7, the Antares DLR-H2 motor glider took off for the first time from Hamburg Airport in Germany. The piloted aircraft is powered by a fuel cell that produces up to 25-kW electric power at a tank-to-propeller efficiency that can reach 44%. The 20-m-wingspan motor glider has a reach of up to 750 km and achieves five hours of flying time. The top speed is around 170 km/h. Antares DLR-H2 was developed by the German Aerospace Center in cooperation with Lange Aviation, BASF Fuel Cells, and Danish Serenergy. The aircraft will be based at Lufthansa Technik for the next three years.
