Geothermal: Clean, Green, Reliable Power

Reddit

I’ve said it over and over: Geothermal is a clean and green way of generating electrical power. It has worked for over 100 years. OK, there’s still more new technology to invent. You can always tweak and improve everything. But the basics are there with geothermal. It’s not rocket science. The world could do just fine by adopting the existing geothermal technology base on a large scale. Really, there are few secrets left to break in the realm of drilling geothermal wells. (Just remember, the rocks tend to be harder and hotter than in oil wells.) And there is not that much new inventing that has to occur in the realm of spinning turbines to generate power.

You surely know that windmills don’t turn when the wind doesn’t blow. And solar does not generate electrons in bad weather or at night. But geothermal runs 24 hours per day, in essence “mining” heat from the bowels of the earth. (That is, the fuel is “free.”) Thus, geothermal offers reliable baseload power. And geothermal emits near-ZERO carbon dioxide (trace amounts at worst), so it completely trumps any and all fossil fuels for a clean power source. There are no long-term waste or storage issues, like with nuclear. There are many locations within the U.S. – and around the world – that are completely suitable for geothermal. Geothermal is a technology whose time ought to be here.

Yes, the time for geothermal ought to be here. So why isn’t the geothermal business exploding? First, geothermal power is competing against a worldwide installed base of existing power systems and economics. When most people think of electricity, they don’t naturally conjure up images of steam wells turning turbines. Few schools anywhere teach future geologists how to “do geothermal.”

Second, the pure-play geothermal companies are small firms subject to the same credit crunch as everything else that has gotten hosed in the past year. (Note, however, that the largest geothermal power player in the world is Chevron.) At the same time, all five of the ESI geothermal companies are following their business plans. There is no bad news from any of them. Each of the geothermal companies is on target and budget. They are generally doing well, with sufficient cash to fund their current business plans. Yet the stock prices of the ESI players are trading flat or down. All I can say is that we should consider it our opportunity to buy a few more shares at low prices and to wait to profit in the future.

Rick Rule has a great way of putting it all in perspective. And I had a long talk with Rick about the geothermal players. Here is some of what he told me.

“Geothermal is easy to understand,” said Rick. “You drill a hole. You lower pipe. You get steam up the pipe from the heat of the earth. You use the steam to spin a turbine. You make electricity. You sell the electricity down the wires. But for as easy as it is to understand, it takes special expertise to put it all together. And the world does not have a vast army of people with that geothermal expertise, as you have with the oil industry. So geothermal is still in a developmental stage. That’s what we have to realize. It takes patience.”

Rick continued: “The good news is that the political and economic climate for geothermal is improving almost every month. Every time the U.S. government, the European Union or the United Nations passes some new regulation about saving the environment, we are one step closer to the geothermal power revolution. Everything that the regulators are doing seems to be making the world tougher for burning carbon and easier for industries that don’t emit CO2. That means that they’re paving the way to a geothermal power build out.”

Rick and I discussed how already, Nicaragua-based Polaris Geothermal is selling CO2 credits to German buyers. “Hey,” said Rick, “if the Germans want to give me euros for my CO2 credits at Polaris, I’ll take their money. Meanwhile, Polaris is operating and selling power to people who want electrical power down in Nicaragua. Eventually, the stock market will figure this out. I’m patient.”

Until next we meet,

P.S. So the future for geothermal is bright. The worst I can say is that the geothermal future is coming slower than I anticipated a year or two back. But it’s coming, of that I’m certain.

In fact, there are three government mandates that could just about guarantee geothermal’s future…and one of these mandates could happen soon…very soon.

I will quote from the movie “The Castle”. You’re dreaming son – lots of luck with them mirrors.

Is geothermal sustainable? You bleed enough energy from the earth’s molten core over a long enough period of time, and w’out the molten core there goes the earth’s protective magnetic field, and we’re stuffed – like Mars.

Is geothermal sustainable? The earth is full of energy You make alcohol out of rotten apples (cider), grapes (wine), vegetable oil and animal fat (for diesel engines for fuel) I saw on top gear UK show how Honda built a car that fills on hydrogen instead of LPG gas and it powers an electric engine Any way Geo will last it is political reason e.g. coal for power stations for electrical supply for general populous (house, apartments, factories) In one of the countries(maybe swiss) I saw a documentary on it and it will supply electricity for mining purposes (if it… Read more »

GaryB’s comment is correct, but only in a basic sense. Like any system – technological, physical, economic, political, financial – it needs to be well managed. Technologically speaking and depending on site conditions, thermal power technology (turbines, condensers, piping, etc) would effectively wear out before a geothermal resource becomes exhausted. Even then, you may reach capacity limits for heat extraction (based on sustainability/extraction criteria – Hotelling’s Rule is a good one), but this is akin to the transmission system’s capacity for carrying electricity anyway. You back it off, and/or supplement, and/or complement, or use efficiency on the demand side. While… Read more »

“It’s not rocket science.” I love it with lawyers dabble in technology…like they would know anything about rocket science anyway :) Yes Byron, the development of technology is easy, you just give things a tweak…oh my…you scare me.

Bond Thanks that was good! There are also problems with radioactive elements encountered but most are not water soluble and pale beside coal which releases colossal radioactivity when burned. The possibility of earth movements exists but in the long term, releasing them is better for stability, even in Australia. We need more, smaller earthquakes. The chemical contamination is a worry as there will be arsenides and such and pumping them back into the ground seems irresponsible, so extraction may have to pay for itself. The real problem is that a small explosion risk exists and siting is easiest far from… Read more »

The big question is why aren’t governments throwing money at sustainable renewable energy like this? The amount of money that has been thrown in as bail-outs and wars would make the sum quite insignificant.
I’d really like to know.

Some governments are throwing money at alternative/renewable energy. Here in Japan one of the key areas the government wants to direct economic stimulus money at is towards the development of alternative energy technology including the next generation of nuclear reactors.

Generating baseload from Solar power is easy. To manage demand for Natural Gas there are great expanding steel reservoirs all around the World. It is easily conceivable that these could be replicated for the purposes of holding hydrogen. As was seen when the Hindeburg went down, Hydrogen burns. When it is burnt it combines with Oxygen in the air to produce water vapour. It is not beyond the realms of either possibility or imagination to use Solar power to divide water into Hydrogen and Oxygen to then produce power when demand outstrips Solar base load supply. What is lacking is… Read more »

Geothermal I thought used recycled super heated water to steam power turbines. Given the closed system the pollution risk is minimal and the source of heat virtually unlimited since no fuel other than magma radiated heat is consumed. Can someone verify this for me please?

Joe: “It is not beyond the realms of either possibility or imagination to use Solar power to divide water into Hydrogen and Oxygen to then produce power when demand outstrips Solar base load supply.” I too thought this. Then I did some research on the ‘hydrogen’ topic. Hydrogen is excellent. You are right, it burns and produces water. In fact, it is excellent in nearly every aspect…except for availability in its pure form (obviously there is an almost unlimited amount in the world where hydrogen is attached to other elements, eg water). Getting hydrogen from water, etc, takes a LOT… Read more »

Bill Foord: Whilst Ausra seems great (I really think it does), it seems to me that it would be majorly flawed aswell. It could only be constructed in areas with high solar temperatures (the desert would be good), but not in areas where there is often cloud cover (eg, northern europe and many coastal areas). Imagine if you had two very overcast and cold days? I bet they can’t keep the heat stored for very long. I think one of the best applications for this technology would be for air-conditioning. You only need aircon when it’s hot, and your solar… Read more »

Pete, you are forgetting Arnie was also a secret agent on Mars, I am guessing they were using plenty of alternative sources of energy up there :)

Haha Greg – some weird alien civilisation’s power source would be pretty handy right now.
