Air New Zealand’s Biofuel Flight Cuts Emissions By 65%

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.

First Commercial Jet Flight Using Jatropha Biodiesel a Success

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.

Air New Zealand Schedules First Commercial Biofuel Flight

On December 3rd, Air New Zealand will be the first commercial airline to power one of its jets with a second generation non-food biofuel made from the Jatropha plant. Jatropha is viewed as having a huge potential as a major source of oil for sustainable biofuel production.

Coconut and Babassu Oil Blend Used in First Virgin Atlantic Biofuel 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 babassu oil are used in cosmetic products, lip balm and other such applications. The raw materials were harvested from existing, mature plantations in Brazil.

Sir Richard Branson, president of Virgin Atlantic is quoted as saying,

“Today marks a biofuel breakthrough for the whole airline industry, Virgin Atlantic nd its partners have proved that you can find an alternative to
traditional jet fuel and fly a plane on biofuel. This pioneering flight
will enable those of us who are serious about reducing our carbon emissions
to go on developing the fuels of the future, fuels which will power our
aircraft in the years ahead.”

There was wide speculation that an algae-based biofuel would be used in the test, but that, of course, proved false even though Virgin Atlantic hinted strongly at the possibility.

According to Radio Netherlands the Boeing 747 landed at Amsterdam’s Schipol airport after a successful flight.

Engineers will now study results of tests taken during the trip to determine if sustainable biofuels will fit into commercial aviation and lessen CO2 emissions.

Not everyone agrees, however, that biofuels will “fly”, as noted here by Pem Charnley, contributor to Green Options’ EcoWorldly blog. His feelings are outlined here, Pies in the Sky.

Algae-Based Biofuel to Power Virgin Atlantic 747 Jet?

Max Lindberg — Tue, 15 Jan 2008 07:47:58 +0000

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 compete with food or fresh water sources. Algae is mentioned several times in the story.

Certain varieties of algae have been identified as a possible feedstock, which contains a much higher energy content than oilseeds and can be far less demanding on the environment.

The engine to be used in the test, GE’s CF6, will not require any modification for the flight, and the use of biofuel is not expected to have a negative effect on the engine’s performance or range.
