Jet fuels obtained from algae, camelina, and jatropha could replace petroleum fuels in commercial flights in 2010, if approved.

Japan Airlines (JAL), the national airline and flag carrier of Japan, has conducted the world's first successful test-flight using biofuel made primarily of a non-food crop called camelina on one of the engines of a Boeing 747-300 aircraft.

  As a part of the efforts taking place around the world to cut greenhouse-gas emissions from aircraft that contributes to global warming, Continental Airlines, based in Houston, Texas, the United States, has conducted a demonstration flight using biofuel. 

Continental Airlines, based in Houston, Texas, the United States, is planning to become the first United States-based airline to fly a jet plane experimentally using biofuel made from a special blend of algae, the jatropha weed and jet fuel.

Air New Zealand, the national flag carrier of New Zealand, has successfully conducted the world’s first commercial aviation test flight using fuel from the seeds of the African jatropha plant.

Japan Airlines Corporation (JAL), United States-based aircraft maker Boeing Company and aircraft-engine manufacturer Pratt & Whitney are collaborating to develop a bio-fuel that can be used as jet fuel. The bio-fuel to be used is a mix of Camelina (84 %), Jatropha (15 %) and algae (approx. 1 %).

Air New Zealand, the national flag carrier of New Zealand, has shown the way in saving fuel, cutting flying time as well as curbing harmful carbon emissions.
