Air New Zealand’s website reports that the airline “expects to use one million barrels of environmentally sustainable fuel annually by 2013”, and is “committed to being at the forefront of testing environmentally sustainable fuels for use in aviation”. In cooperation with American aircraft-manufacturer Boeing, Air New Zealand is planning a three-hour test flight on a Boeing 747 aircraft, with one of its four engines powered by jet fuel produced from Jatropha oil. The jatropha-based jet fuel is reportedly developed at a research facility in Hawaii. The test flight, which is scheduled in the next few months, “will be the world's first flight test on a large passenger aircraft using fuel sourced from the plant, Jatropha”. If the test flight is successful, the fuel will be gradually used on all four engines in future test flights. Chief Executive Officer Rob Fyfe says that Jatropha meets all the three criteria set by the company for an environmentally sustainable fuel to be considered for flight testing: (1) the biofuel feedstock must not have food uses, (2) the biofuel product must be as good as existing fuels that the airline uses, and (3) the biofuel must be “significantly cheaper than existing fuel supplies and readily available”. The Next Energy News website reports that the Jatropha will be sourced from southeastern Africa and India, and that the oil will be refined into jet fuel at an unspecified "hydro plant" in the United States..
