At the Eco-Aviation Conference in Washington, Air New Zealand’s Chief Pilot Captain David Morgan announced the company’s findings on a test flight from last December. Powered by a combination of biofuel and jet fuel, the test resulted in a fuel savings of 1.2%. It also cut CO2 emissions by over 60%!
While a 1.2% fuel savings doesn’t seem like much, that is over 1 ton of fuel!
The test was conducted using a commercial 747-400 fitted with Rolls Royce engines. Rolls Royce had certified the fuel — a 50:50 blend of standard Jet A1 fuel and synthetic paraffinic kerosene derived from jatropha oil.

After postponing the flight for about a month, Air New Zealand has become the first airline to test a 50/50 blend of second generation jatropha biodiesel and standard A1 jet fuel in a Boeing 747-400 passenger jet. The company has hailed the test as a milestone for commercial aviation.

The flight lasted two hours and ran one of the plane’s Rolls-Royce engines on the jatropha biodiesel blend. Air New Zealand has previously stated that they want to become the world’s most sustainable airline and hopes that by 2013, 10% of its flights will be powered by biofuel blends such as the jatropha biodiesel blend used in this test flight.

Virgin Atlantic Airlines has used a sustainable fuel from biomass mixed with traditional jet fuel to power one engine on a 747 flight from London Heathrow to Amsterdam. The fuel was supplied by Imperium Renewables of Seattle, Washington, a commercial biodiesel refiner.
As promised in their earlier news releases, Virgin Atlantic said they would use a sustainable fuel made from feedstock not normally used for food products. Both coconut oil and [...]

A Boeing 747 jet, using 20 percent biofuel in one engine, is expected to take off from London’s Heathrow Airport and fly to Amsterdam in late February. The test flight will be without passengers and is part of a research project being conducted by the airline, Boeing and the maker of the engine, GE Aviation.
Interestingly, sources were specific that the biofuel used will be from a very sustainable source, but not one that would [...]
