Easy-to-grow plant could be next hot fuel

Countries from Swaziland to China are devoting thousands of acres to an easy-to-raise plant that may be biodiesel's best bet.

The Christian Science Monitor

JAGDALPUR, India — In an overgrown corner of Moolchand Sethia's plantation, runty and unloved, stands what could be the next revolution in the world's search for renewable fuel.

From China to Brazil, countries have begun setting aside tens of thousands of acres for the cultivation of jatropha — a plant many experts say is the most promising source for biodiesel. At the same time, companies from Europe and India have begun buying up land throughout Africa to establish jatropha plantations.

As American farmers plan to plant the most corn since World War II to cash in on ethanol, which is added to gasoline, much of the rest of the world is turning to jatropha, which is used as a substitute for diesel fuel.

The two are not competitors, since neither can be used in the other type of fuel. But jatropha is fast emerging as a candidate for the ideal biofuel. It is grown in wastelands, needs relatively little care or refinement, and is inedible — meaning it will not take food from the poor for the gas tanks of the rich.

But Sethia's modest plantation is a reminder that jatropha has a long way to go. Although Sethia's home state of Chhattisgarh has been one of India's leading jatropha promoters, industries say it could be years before production starts here.

There is no estimate as to how much jatropha is being cultivated globally, but anecdotal evidence suggests that the trend is accelerating:

• The government-owned China National Offshore Oil Corp. (CNOOC) is planning to have 80,000 acres of jatropha in Sichuan Province alone by 2010.

• Renova Biodiesel of Brazil is expected to plant 60,000 acres of jatropha, and reports suggest that other oil companies are considering planting nearly 500,000 acres in the next four years.

• D1 Oils, a British company that is considered by many to be the leader in jatropha cultivation, has plantations from Swaziland to Indonesia, and hopes to nearly double its 385,000 acres of jatropha worldwide by the end of 2008.

• The Philippine National Oil Co. recently earmarked $14 million for jatropha planting and production, while Indonesia plans to set up 52 biodiesel plants across the country at a cost of $7.3 million.

The cause of the excitement is both environmental and economic. The European Union has mandated that by 2020 all cars must run on 20 percent biodiesel, which burns cleaner than fossil fuels. A 1998 study, jointly sponsored by the U.S. Department of Energy and the Department of Agriculture, concluded that biodiesel reduces net carbon-dioxide emissions by 78 percent compared with petroleum diesel.

Meanwhile, Asian economies are desperately seeking natural resources to support their growth. India, for example, imports 70 percent of its fuel.

Jatropha is a natural answer. The leafy bush thrives in arid regions around the equator, has no use as food, and takes little refinement: a hydraulic press to squeeze the oil from the seeds, and a chemical solution to create and filter the fuel. When the necessary infrastructure is in place — sufficient farms, transport routes, and processing plants — jatropha oil could be no more expensive than regular diesel.

Along with several other states, Chhattisgarh has responded with massive planting campaigns and incentives for farmers, including 500 free saplings. Sethia received a $250 loan for planting jatropha. The problem is, there's no market here in the Indian outback.

The state says it will buy the seeds, which then must be crushed to create the oil. But Sethia says he would need to take his harvest to the capital, which is a half-day drive, at least. The cost of getting it there would outstrip any possible profit.

There is also a danger in industries pushing too fast, experts say. Jatropha cultivation is so new that scientists know little about it, such as ideal conditions for growth, susceptibility to disease, or expected yields.

The Energy and Resources Institute in Delhi has set up plantations across India to study these issues for British Petroleum. In four years, all these knowledge gaps will be filled in, argues Alok Adholeya, who manages the program.

He advises farmers like Sethia to remain patient: "If they are patient enough, they will find some buyers very soon, because the message is getting out."
