Japan Airlines biofuels flight test a success; camelina, algae, jatropha used in B50 biofuel mix; fuel economy higher than Jet-A In Japan, Japan Airlines became the fourth airline to successfully flight test biofuels in the past year, and the first to successfully demonstrate camelina as a biofuel feedstock. The airline conducted a one-hour 747-300 flight test using a B50 blend of camelina, jatropha and algae based biofuel in the number 3 engine. The jatropha was supplied by Terrasol, algae oil by Sapphire Energy, and the camelina oil by Sustainable Oils. The biofuel was 84 percent camelina, 16 percent jatropha, and less than one percent algae.The fuel was processed by Honeywell’s UOP subsidiary, and supplied by a joint venture of UOP and JGC, Nikki Universal. In ground tests conducted yesterday, the pilots reported that the biofuel was more fuel efficient than 100 percent traditional jet-A fuel (kerosene), a finding consistent with the Continental test last month, and indicates that biofuels may not only be a carbon-neutral option, but a more fuel efficient one. Pratt & Whitney, which manufactures the engines used in the test, confirmed that the biofuel met of exceeded performance criteria established for commercial aviation jet fuel. Boeing Japan president Nicole Piasecki said that the company is hopeful of flying revenue passenger flights within 3-5 years using biofuels．
