Jatropha curcas Use as fuel

Particular interest is being converted to biodiesel, and especially cold-pressed vegetable oils, particularly the financially weak tropical countries spared the costly oil imports, because it can be directly used in specially adapted engines. In cooperation with the Society for Technical Cooperation (GTZ) and the University of Stuttgart-Hohenheim is therefore forced into a research and production project in the Indian Gujarat the cultivation of the plant. By then produced fuel diesel engines can be operated that meet the emission standard Euro 3.

The seeds have an oil content of more than 30%, which on top with a cetane number of about 60 (biodiesel made from rapeseed oil, only about 54) is a very effective, is technically usable vegetable oils. The cultivation is therefore especially rewarding, not only for the subsistence economy (oil production for own use), but also for resale on the international market. Currently (as of July 2008) is the worldwide crop, with nearly 1 million hectares, about 80% of this area accounts for attention to the Asian countries, especially India, China and Indonesia. But experiences in South America and Africa, the commercial jatropha mounting a boom. New studies indicate that worldwide, there is a growing potential of about 300 million hectares.

Boeing and Air New Zealand have developed a research project in a biological airplane fuel, which consists of equal numbers of Purgiernussöl and kerosene. The first flight with this fuel has on 30 December 2008 took place. To a jumbo jet was used, in which a Rolls-Royce RB211 engine was operated with the new fuel. The fuel has a freezing point at -47 ° C and a flash point at 38 ° C and thus has similar properties to the most commonly used grade kerosene Jet A-1. Also, Continental Airlines and Japan Airlines are planning to conduct test flights in January 2009. The TAM is planning this for the second half of 2010.

On 9 January 2008 shared the Bayer AG, the U.S. agricultural company Archer Daniels Midland Co. and automaker Daimler AG to want to research and develop in cooperation Jatropha curcas as a supplier of raw materials for industrial production of biodiesel. In this context, the companies intend to define binding production and quality standards for biodiesel produced from jatropha.
