Air New Zealand and Boeing announce sustainable jatropha biofuel test flight

Air New Zealand and Boeing today announced Dec. 3 as the date for the airline's sustainable biofuels flight from Auckland using a 747-400 jetliner. Conducted in partnership with Rolls-Royce and UOP, a Honeywell company, one of the airplane's four Rolls-Royce RB211 engines will be powered in part using advanced generation biofuels derived from jatropha. Air New Zealand now becomes the first airline to use a commercially viable biofuel sourced using sustainability best practices.

Boeing, Air New Zealand and UOP have worked diligently with growers and project developer Terasol Energy to identify sustainable jatropha in adequate quantities to conduct thorough preflight testing. Using proprietary UOP fuel processing technology, the jatropha crude oil was successfully converted to biojet fuel, marking the world's first large-scale production run of a commercially viable and sustainable biofuel for aviation use.

"This flight strongly supports our efforts to be the world's most environmentally responsible airline," said Air New Zealand Chief Executive Officer Rob Fyfe. "We recently demonstrated the fuel and environmental gains that can be achieved through advanced operational procedures using Boeing 777s. We're also modernizing our fleet as we await our Trent 1000-powered 787-9 Dreamliners, which will burn 20 percent less fuel than the planes they replace. Introducing a new generation of sustainable fuels is the next logical step in our efforts to further save fuel and reduce aircraft emissions."

As part of the fuel verification process, UK-based engine maker Rolls-Royce's technical team conducted extensive laboratory testing to ensure compatibility with today's jet engine components and to validate the fuel meets stringent performance criteria for aviation fuel.
"In preparation for Air New Zealand's test flight we achieved our near-term goal - identifying and sourcing the first large-scale run of sustainable biofuel for commercial aviation," said Boeing Commercial Airplane's Managing Director of Environmental Strategy Billy Glover. "The processing technology exists today, and based on results we've seen, it's highly encouraging that this fuel not only met but exceeded three key criteria for the next generation of jet fuel: higher than expected jet fuel yields, very low freeze point and good energy density," Glover explained. "That tells us we're on the right path to certification and commercial availability."

Because of the unique environment in which aviation operates, stringent criteria are in place to ensure that any alternative fuel meets or exceeds current jet fuel requirements. Advance testing for the Air New Zealand flight showed that the jatropha-based biofuel met all critical specifications, including a freeze point at -53 degrees Fahrenheit (-47 degrees Celsius) and a flash point at 100 degrees Fahrenheit (38 degrees Celsius).

"Laboratory testing showed the final blend had excellent properties, meeting and in many cases exceeding the stringent technical requirements for fuels used in civil and defense aircraft," said Chris Lewis, Rolls-Royce company specialist for fuels. "The blended fuel therefore meets the essential requirement of being a 'drop-in' fuel, meaning its properties will be virtually indistinguishable from conventional fuel, Jet A1, which is used in commercial aviation today."
To process the jatropha crude, the team relied on UOP's green jet fuel processing technology based on hydroprocessing methodologies that are commonly used to produce transportation fuels. During processing, hydrogen is added to remove oxygen from the biomass, resulting in a bio-derived jet fuel that can be used as a petroleum replacement for commercial aviation. Boeing is working with airlines and engine manufacturers to gather biofuel performance data as part of the industry's efforts to revise the current American Society for Testing and Materials (ASTM) standards to include fuels from sustainable plant sources. Jatropha, which can be grown in a broad range of conditions, produces seeds that contain inedible lipid oil that is extracted and used to produce fuel. Each seed produces 30 to 40 percent of its mass in oil. Plant oil used to create the fuel for the Air New Zealand flight was sourced from nonarable lands in India and Southeastern Africa (Malawi, Mozambique and Tanzania).

Air New Zealand is one of several air carriers working to diversify and secure its energy future through participation in the Sustainable Aviation Fuel Users Group. That effort includes a commitment to sustainability criteria for fuel sourcing and commercializing plant-based fuels that perform as well as, or better than, kerosene-based fuel but with a smaller carbon lifecycle. The goal is to create a portfolio of next-generation biofuels that can be blended with traditional kerosene fuel (Jet A) to improve environmental performance.

Additional flight specifics will be announced closer to the actual flight date.

West Bengal turns to Jatropha farming to promote bio-diesel

The West Bengal government has taken up a programme to develop cultivation of Jatropha plant to popularise it as a major source of bio-diesel. A survey is also proposed to identify the various species of Jatropha available in the state with special emphasis on districts where the growth of the plant is rampant, Saumendra Nath Bera, chairman of the Standing Committee on Science and Technology and Bio-Technology in the state assembly, said.

The project will be taken under a Micro-Mission Project of Jatropha under the Union Bio-Technology department. Describing Jatropha oil as a "potential source of fuel," Bera said the survey would enable identification of the varieties and its required soil and climatic conditions for obtaining appropriate quality planting materials with maximum oil content.

Bera, who recently undertook a study visit along with other members of the Standing Committee to Garmandaran in Hooghly district, said field trials for large-scale cultivation of Jatropha had been undertaken at Hooghly and Bankura.

"Its cultivation is proposed to be extended to other districts depending on the total area of cultivation and total seed production," he said.

Quality planting materials to be produced by macro propagation would provide quality seeds for oil extraction, Bera said adding that in order to provide good planting material, saplings were being produced from seeds and cuttings.

The Centre's Micro-Mission Project of Jatropha was aimed at large-scale propagation of the plant for identifying species with maximum oil content and large-scale propagation of quality planting materials, Bera said. Describing both the seeds and cuttings as the source of planting materials for this demonstration project at Garmandaran, he said 15 hectares of land were covered there for three years, of which five hectares were completed in 2005-06 and the rest to be covered within the current year.

Thenergo to invest in a jatropha nuts power plant

Thenergo, a developer of combined heat and power (CHP) energy systems, said it will invest 11 million € to develop a CHP plant at Merksplas, Belgium, to be fuelled by jatropha nuts.

Thenergo claims the 'Greenpower' project will be operational for up to 8,000 hours per year, or approximately 11 months of the year, generating 6MWth of heat for two industrial partners, and 9MWe of electricity for the equivalent of 20,000 households.

The unit is expected to be operational in February 2009.

Greenpower is a joint venture between Thenergo, the majority shareholder and operator, and the Quirynen and the Dielis families.

Greenpower will run on bio-oil extracted from the nuts of the jatropha plant. The jatropha nut is a non-edible fruit grown on semi-arid or waste land in South East Asia.
