Air China, Boeing and other Chinese and US aviation energy companies have conducted a trial of a passenger plane powered by a 50:50 mix of biofuel and traditional aviation fuel.

The biofuel used during the trial of a Boeing 747-400 flight was produced by PetroChina and UOP, a Honeywell company.

The two-hour flight from Beijing Capital International Airport burned more than 10t of biofuel, demonstrating that the fuel is now ready to be used for commercial flights.

China’s National Energy Administration (NEA) and Boeing have announced an agreement for further study of regional biofuel development, which will help establish a sustainable aviation biofuel industry in China.
