An MIT-led study of the potential for geothermal energy within the United States published in 2007 found that Enhanced Geothermal System (EGS) technology could supply a substantial portion of US electricity well into the future, probably at competitive prices and with minimal environmental impact. Overall, the panel concluded that EGS can likely deliver cumulative capacity of more than 100,000 MWe within 50 years with a modest, multiyear federal investment for RD&D. The panel estimated the total EGS resource base to be more than 13 million exajoules (EJ), with an estimated extractable portion to exceed 200,000 EJ—about 2,000 times the annual consumption of primary energy in the United States in 2005.

One geothermal company was extracting Zinc from their wells in California, but the gave up the effort due to low zinc prices before the speculative oil and commodity price run up. It is too bad that this effort was not re-instituted. What other metals or minerals can be extracted.

It is not widely known that some natural geothemal areas produce a lot of CO2. Are these enhanced geothermal processes also going to produce more CO2?

In addition geothermal sytems can release lot of radio-activity in the form of radon and dissolved daughter products, but the total amounts will be far below that produced with natural gas. It must be realized that geothermal energy is nuclear energy from the partial fission of thorium and uranium and drilling will be done through more or less radio-active rock.

There is not a word about directional drilling for tapping larger areas.

The efforts to exploit Geothermal energy may pay off in an entirely different area. Small units can be used to extract electricity from burning natural gas in home and business heating systems. Whilst the electricity is not FREE, it is produced in a far more efficient way than is done by burning the natural gas at central power stations. The burning of natural gas at central power stations should be forbidden by law in favor of small and large cogeneration units. There is an energy saving that can approach %60 and the CO2 saving is %40. The LION steam free piston unit, Wispergen, Honda et cetera are examples of this type of small cogeneration units. Larger units are the Capstone 30 to 200 kilowatt air bearing microturbines. No large home owned by a Hollywood superstar should be without a Capstone unit. Lesser stars should be required to have the Honda units; Perhaps multiple units. It is widely known technology of how they can use them. ..HG..


Doesn't geothermal have earthquake problems?


In granite belt areas the steam/froth will have to be looped to contain the radon gas. All this research money for drilling may be misdirected unless they get the surface technology right, for example the Kalina heat exchanger system with mixed water and ammonia. Note the huge energy needed to drill deep into granite (repeated as a rock volume is cooled) cuts into the EROEI which I suspect is very low. Even district heating as opposed to pure electrical generation may be inefficient compared to solar and gas CHP.


There have been problems with a project in Switzerland that was located in a geologically unstable area. I think the project was discontinued This may be more of an issue for projects tapping existing underground geothermal water resources.

Hot Dry Rock projects are not usually located in unstable areas and therefore not subject to these problems.

Please share the source of your information with us, and if you can, how much CO2/kWhr, how many plants, etc.

Of the things that the greenwackos never consider is to wonder why "Official renewables" have not been more utilized, to date. The reason that the so-called "renewables" are not utilized more today, is that they are largely uneconomic; and or limited in some fundamental way.

Excluding Hydro which is a reasonable and exploited power source, Geothermal is probably the most feasible of the wet dreams of the Greenies. It holds the prospect of substantial temperature differentials and therefor a reasonable efficiency, unlike wind, or solar, since thermal efficiency is proportional to temperature differences.

Geothermal suffers from at least five fundamental problems.

First, despite the propaganda, the exploitable geothermal places with combinations of usable, regenerating heat, reasonable ranges of working temperatures, and no consequences, is largely limited geographically, to seismic active areas.

Second, the life expectancy of a heat reservoir is somewhat indeterminate. There have been geothermal projects undertaken with a heat reservoir regeneration lifetime estimated at plus 30 years or more, that start exhibiting limits, i.e. plunging temperatures, and short lives after only several months of operation. This has bankrupted the investments, in the oast, and limited financing options to many others. The problem is not just the overall heat availability, but the heat transfer regeneracy rates within the reservoir too. But greenidiots never learn any engineering or economics, so they always think it must be a conspiracy of sort.

Third, corrosion problems are an ever present problem. Unlike a carefully controlled environment where clean steam is used in a power plant, the geothermal wet steam, is full of various dissolved materials. Many times the steam is really not steam at all, but rather a sulfuric or nitric gaseous acid, or perhasp a basic hydroxide. Needless to say that is not conducive to the life expectancy of turbines, turbine blades, or piping, in either case.

Fourth, toxic emissions have been a problem in many geothermal locations. I am not only speaking of CO2 emissions as discussed but dangerous gases such as H2S, SOx, and others as well.

Fifth, there is some trepidation in exploiting a magma pool for its heat. Especially, when your multimillion dollar investment may be sitting on a nascent volcano. As you would expect its hard to arrange long-term financing, as well.

Finally, since geothermal sources are where you find them, they are most often far from consumers of the power produced. Just like the "stranded" solar and windfarms in California, and also in T Boone Pickens Texas facilities, it is difficult to over come the NIMBY resistance to power lines and to secure rights of way.

For all these reasons, the most feasible of the so-called "official renewables" has had but a very limited success to date. And that probably won't change.

There are benefits for geothermal. But at least unlike the solar and wind illusions, geothermal provides a reasonably consistent and non-intermittent source of power. There is not the kind of wild oscillations induced into the power grids that are a disastrous feature of the other varying and intermittent "renewables", that so haunts the Netherlands, the UK, and T Boone's wind power empire.


The number - estimated extractable portion to exceed 200,000 EJ is impressive. It also sounds from comments and research areas as though there are major problems getting equipment to operate consistently at 300+C. Clearly however, given the potential for this source of clean, renewable energy - it should remain on the fastrack for inclusion in the new, overall energy portfolio.

Ideally we will build fully functional generating plants in all the major categories: solar, wind, geothermal, nuke, and even "clean" coal with CCS. Let them compete in near and long term on efficiency and economics. These will be the technologies that vie for dominance in the new HVDC-fed grid developed to power large consumers, industry and government. Meanwhile, small, micro/co-generation, hybrid solar/electrolysis, LENR, and r-t plasma, RPUs will gradually offload residential demand from the grid.

We lower projected demand on the HVDC grid prior to its build out. This is accomplished by consumer conservation, education and development of Residential Power Units that contribute to neighborhood local area grids (same wire, different business model.)

Distributed generation guarantees security, leveling and backup power via multipoint energy sources. Old power companies gradually divest the residential portion of their local demand and build a new industry by manufacture and service of RPUs. This provides far more good, long term jobs and security than a continuation of the old (in-secure) utility model of single point distribution.

@ HG: "Lesser stars should be required to have the Honda units; Perhaps multiple units." While excellent for Honda, even lesser stars and regular folks should be offered choice. But co-generation is a good step.

You'll find that you are far out of date (or completely off track) with your points, so it would be wise to learn the current technologies before ranting about those in the receding past.



Gee Stan you must love this site, where else can you go and abuse everyone you see?

Well go for it mate you obviously have some personal problems - we are here to help for sure, but maybe there are more appropriate anger management or counseling sites that would better suit your needs.

Might even be some you dont have to pay for.

Maybe some regulars could help out with a subscription?

There is a far greater amount of abuse heaped on any at GCC who deign question the science of AGW. And those who discuss the Medieval Warm Period, nuclear energy, ethanol or any American [fill in the blank] - are equally hounded. We might suggest that these "green extremes" be admitted for a checkup from the neckup. Their hostility permeates this and other "green" sites, further tarnishing the green cause.

It's an informative site - too bad prejudice is so abundant.
