More Taxpayer's Money Wasted By Government: Geothermal Energy Failure

I could say I "told-ya so". Economic, large-scale geothermal energy production is an illusion, promoted by many of the same environmental "do-gooders" who have brought us the man-caused global warming fiasco. If this was being done only with private funding there would be little cause for concern. If it was free enterprise at work to harness heat energy from within the Earth, it could be applauded. However, this is largely taxpayer's money being wasted and we should be aware of it.

In light of the ClimateGate scandal and the tremendous amount of money being wasted on the myth of man-caused global warming, we must second-guess and carefully scrutinize everything the Government does. They seem almost completely out-of-touch with reality and are locked into an ever-increasing mode of tax-spend, tax-spend. Will this go on until America is economically bled-dry, like the former Soviet Union?

Geothermal Project in California Is Shut Down

The company in charge of a California project to extract vast amounts of renewable energy from deep, hot bedrock has removed its drill rig and informed federal officials that the government project will be abandoned.

The project by the company, AltaRock Energy, was the Obama administration’s first major test of geothermal energy as a significant alternative to fossil fuels and the project was being financed with federal Department of Energy money at a site about 100 miles north of San Francisco called the Geysers.

But on Friday, the Energy Department said that AltaRock had given notice this week that “it will not be continuing work at the Geysers” as part of the agency’s geothermal development program.

The project’s apparent collapse comes a day after Swiss government officials permanently shut down a similar project in Basel, because of the damaging earthquakes it produced in 2006 and 2007. Taken together, the two setbacks could change the direction of the Obama administration’s geothermal program, which had raised hopes that the earth’s bedrock could be quickly tapped as a clean and almost limitless energy source.

The Energy Department referred other questions about the project’s shutdown to AltaRock, a startup company based in Seattle. Reached by telephone, the company’s chief operations officer, James T. Turner, confirmed that the rig had been removed but said he had not been informed of the notice that the company had given the government. Two other senior company officials did not respond to requests for comment, and it was unclear whether AltaRock might try to restart the project with private money.

In addition to a $6 million grant from the Energy Department, AltaRock had attracted some $30 million in venture capital from high-profile investors like Google, Khosla Ventures and Kleiner Perkins Caufield & Byers.

“Some of these startup companies got out in front and convinced some venture capitalists that they were very close to commercial deployment,” said Daniel P. Schrag, a professor of geology and director of the Center for the Environment at Harvard University.

Geothermal enthusiasts asserted that drilling miles into hard rock, as required by the technique, could be done quickly and economically with small improvements in existing methods, Professor Schrag said. “What we’ve discovered is that it’s harder to make those improvements than some people believed,” he added.

In fact, AltaRock immediately ran into snags with its drilling, repeatedly snapping off bits in shallow formations called caprock. The project’s safety was also under review at the Energy Department after federal officials said the company had not been entirely forthcoming about the earthquakes produced in Basel in making the case for the Geysers project.

The results of that review have not yet been announced, but the type of geothermal energy explored in Basel and at the Geysers requires fracturing the bedrock then circulating water through the cracks to produce steam. By its nature, fracturing creates earthquakes, though most of them are small.

On Friday, the Energy Department, which has put some $440 million into its geothermal program this year alone, said that despite the latest developments, it remained confident of the technology’s long-term prospects. Many geothermal methods do not require drilling so deep or fracturing bedrock.

“The Department of Energy believes that geothermal energy holds enormous potential to heat our homes and power our economy while decreasing our carbon pollution,” said Stephanie Mueller, a spokeswoman.

AltaRock has also received some $25 million in federal money for a project in Oregon, and some scientists speculated on Friday that after the spate of problems at the Geysers, the company wanted to focus on a new site.

But the company, whose project at the Geysers was located on land leased from the federal government by the Northern California Power Agency, has held information about its project tightly. Not even the power agency has been informed of AltaRock’s ultimate intentions at the site, said Murray Grande, who is in charge of geothermal facilities for the agency.

“They just probably gave up, but we don’t know,” Mr. Grande said. “We have nothing official from them at all.”

But a resident of the nearby town of Anderson Springs, which is already shaken by quakes generated by less ambitious geothermal projects, reacted with jubilation when told it appeared the new project was ending.

“How I feel is beyond anything that words can express,” said the resident, Jacque Felber, who added that an unnerving quake had rattled her property the night before. “I’m just so relieved, because with this going on, I’m afraid one of these days it’s going to knock my house off the hill.”

The project mentioned in this article was most liekly shut down due to the very negative attacks from the local media and reference to a project in Bern Switzerland that triggered a a small earthquake in a highly populated area. The process of fracturing deep rock is extremely common in the oil and gas industry. It is safe and a proven method of increasing production. Geothermal is a very viable energy source but unfortunately misunderstood by the layman. There are also many other forms of geothermal energy production that does not involve fracturing subsurface formation. It is probably the MOST safe and certain of the alternative energy sources being experimented with.

Allan,
My graduate work at the Colorado School of Mines over 30 years ago involved a National Science Foundation Grant to evaluate the geothermal energy potential of a portion of northwestern Nevada.

Geothermal energy has been known about for a long time, but is only economic in rare instances. Like so many things, it sounds good in theory and is extremely difficult in reality. I do not see geothermal energy as a panacea for our energy needs.

Peter,
It looks like you are a fellow Badger! I do agree that Geothermal is not a Panacea for our energy needs, however there are some relatively new developments in Binary and Kalina cycle systems that can generate electricity at relatively low temperatures (180-200 F.)
You may want to look at some companies like Ormat, and Razer technologies (I don't own any stock in these companies). They are doing some remarkable things at low temperatures. The worldwide potential for geothermal is enormous. Indonesia and the Phillipines already use a great deal of geothermal energy and Australia is spending vast sums of money developing geothermal potential
The US needs to tap this clean and inexpensive energy source.

When Exxon/Mobil spends 31++$Billion on XTO Gas....I pay attention.......so should you.......geothermal is dead................Natural gas and shale gas is the future.........

Allan said...

Natural Gas is indeed a great relatively clean fuel. I think that infrastructure in the U.S. needs to adequately enable the use of natural gas in virtually all automobiles.
The Exxon acquisition that you mention is primarily for shale gas exploitation. Guess how that process works?.......massive fracturing of the shale formation causing the "mini earth quakes" mentioned in the article above that shut down the AltaRock project. Too bad people don't understand that.

I'm going to look into the information you posted on geothermal, thanks. I'm pretty busy at the moment.
