thejakartapostU.S. energy giant Chevron is ready to launch a 110-megawatt (MW) geothermal power plant project in Garut, West Java, after a team was set up to hopefully resolve a variety of problems with the local administration.
Located in the "ring of fire" volcano belt, Indonesia is thought to have about 40 percent of the world's geothermal reserves, equivalent to a total of 27,140 MW of power. While the country has several operational geothermal power plants, their combined capacity currently is only 807 MW or about 3 percent of the country's total geothermal potential.
I guess geothermal makes economic sense despite the high price, since Indonesian power plants otherwise are oil-fired. But why does Chevron build the plant? Aren't they an oil company? I thought GE or ABB would do these kind of projects."The price will be above 4 U.S. cents (per kilowatthour)," said Yudiana.
Maybe they want to keep the oil which would have fired the power plant and sell it for motor fuel on the world market?Starvid wrote:I guess geothermal makes economic sense despite the high price, since Indonesian power plants otherwise are oil-fired.

An interesting article, obviously not going to help with liquid fuels, but the ability to tap geothermal anywhere has potential. Hack away. linkyAn MIT chemical engineer explains why new technologies could finally make "heat mining" practical nearly anywhere on earth.

Energy, it is the first study in some 30 years to take a new look at geothermal, an energy resource that has been largely ignored.
This new study takes a more ambitious look at this resource and evaluates its potential for much larger-scale deployment.
"We've determined that heat mining can be economical in the short term"
The expert panel offers a number of recommendations to develop geothermal as a major electricity supplier for the nation.
Unlike conventional fossil-fuel power plants that burn coal, natural gas or oil, no fuel would be required. And unlike wind and solar systems, a geothermal plant works night and day, offering a non-interruptible source of electric power.
Government-funded research into geothermal was very active in the 1970s and early 1980s. As oil prices declined in the mid-1980s, enthusiasm for alternative energy sources waned, and funding for research on renewable energy and energy efficiency (including geothermal) was greatly reduced, making it difficult for geothermal technology to advance. "Now that energy concerns have resurfaced, an opportunity exists for the U.S. to pursue the EGS option aggressively to meet long-term national needs," Tester observed.
But geothermal is not entirely risk-free. A recent effort to build such a geothermal power plant in Basel, Switzerland, came to an abrupt halt when it triggered an earthquake measuring 3.4 on the Richter scale, too small to cause damage but large enough to be felt by humans. "We generate between 3,000 and 5,000 earthquakes a year," Calpine's Gilles says.
