Earlier this week, the world’s first piloted aircraft powered solely by hydrogen fuel cells, took to the skies above Hamburg Airport, Germany, producing zero carbon dioxide emissions.

The Antares DLR-H2, jointly developed by the German aerospace centre DLR, Lange Aviation, BASF Fuel Cells and Denmark’s Serenergy, has a range of 750km (390nm) and can stay airborne for 5 hours at top flying speeds of about 90kt (170km/h).

According to DLR, a main hurdle was improving fuel cell performance capabilities and efficiency to such an extent that the motor glider could take off using fuel cell power alone. DLR’s Johann-Dietrich told reporters, “This enables us to demonstrate the true potential of this technology.” (see more pictures after the jump).

Earlier this month, pilots Carol Sugars and Douglas Rodante made history by becoming the first flight-crew to successfully fly across the US in a plane predominantly powered by biodiesel.

Of the total 2,486 miles flown from Reno, Nevada to Leesburg, Florida, 1,776 miles were 100% biodiesel-powered. The remaining 710 miles were powered by a 50/50 mix of biodiesel and standard jet fuel.
