Jatropha fuel: A flight test conducted by Air New Zealand has shown that 1.4 tons of fuel can be saved in 12 hours


A flight test conducted by Air New Zealand has shown that 1.4 tons of fuel can be saved in 12 hours, using a fuel composed of 50% of jatropha.

The study was conducted on a Boeing 747-400 built by Rolls-Royce. The test flight in December 2008 was powered by a fuel composed of 50% of fuel from jatropha, in addition to traditional JETA1.

The tests were conducted on the ground and in flight at different altitudes and in different flight conditions. The engine and components were studied.

The use of this mixture on a flight of 12 hours of 1.2% would reduce consumption of the aircraft, or 1.43 tonnes of fuel. Over shorter distance, the consumer economy is 1%. From the point of view of CO2 emissions, the reduction would be 4.5 tons, or 60 to 65% less than conventional fuel.

"It is certain that the data from our test flight on biofuel is a critical component to help biofuels to become a certified aviation fuel" welcomed Commander David Morgan.

"Currently, our research team options biofuels. We stand by our ambition to meet up to 10% of fuel needs in 2013 through use of alternative fuels, but recognize that there are several steps by experts in other fields. " he added.

The initiative was undertaken jointly by Air New Zealand, Boeing, Rolls-Royce, Honeywell and UOP.
