It has not lived up to the hype and it will be years before it can compete agronomically with soya and it is not scalable to the refining industry’s needs under small scale farming. Small scale rural farmers are more easily integrated into Jatropha based electrification in underdeveloped rural areas.

The Jatropha Spin

Jatropha curcas, also known as the Physic nut, is a perennial poisonous shrub. It is an uncultivated non-food wild-species that grows easily in hedges and scattered around homesteads.  It was spread from Central America to Africa by Portuguese traders who introduced it as a hedge material and a source of oil for light.

Most importantly, it did not rely on corn or other food stocks in order to produce fuel. At the time, Coskata was predicting an aggressive timeline, with a pilot demonstration plant to begin operation in 2009, and a first full-scale plant to be underway by 2011.

Last week Coskata announced the location for their pilot demonstration plant, a facility that will begin producing 40,000 gallons of ethanol per year, starting in 2009. While that is only a tiny drop in the proverbial bucket, it’s another step along the path to having a full-scale plant in operation and producing 50 to 100 million gallons of ethanol per year.
