Dozens before the snow fliesHundreds by 2010.
Two good possibilities exist. (1) Nuclear retrofit, to stop adding to the problem. Coal combustors are hard to feed, hard to babysit, and yet all they do is supply hot gas, I'm not a coal-fired plant expert but I think 600 Celsius is hot enough, to steam generators. CANDU reactors have cool heavy water for bulk moderation, hot heavy water in the fuel channels for cooling. Because in the latter circuit it is kept liquid, it is ...read more
Political Snake OilGov. Schweitzer is just chumming the waters for coal investors, and starting to smell like a fish left too long in the sun.
Energy investors still remember the 1986 oil price collapse. If US political leadership pulled for efficiency, like car pools, then the savings would be millions of barrels of oil per day and the world oil price would collapse.
Political leadership that push favorite local energy industries do not appear honest nor low risk. ...read more
If it's so easy and cheap to sequester carbon...why aren't the nations in a race to do it now?

Everything in the desert?Doesn't it seem a little impracticle to have all of our power generation located in the desert?
What about the workers at the plant? What about the fact that there is no energy demand out there?
Or did I misunderstand the quote. It was a little jargony.

Gasification and SequesteringThere are oppurtunities to build some, cleary not hundreds, gasification plants and sequester for enhanced oil recovery. Granted these oppurtunties are limited to oil fields but generally the coal has to be shipped and it make more sense then to ship the coal and use the CO2 locally.
Consider TU recent annoucement to build 8 coal plants in Texas. Sound like a great place for enhanced oil recovery.
I am sure Texas rate payers would be happy, in ...read more
Capture onlyThe CO2 capture plants would do only capture, compensating for CO2-emitting power generation elsewhere on the planet -- anywhere else at all, since the whole atmosphere mixes in a few years. (One way it is known for sure that increased atmospheric CO2 is from fossil fuel combustors, and not a cosmic coincidence, is that the increase lags by a few years in the southern hemisphere. There are also isotopic clues.)

Boron: internal combustion without exhaust gas
Coal articleon the front page of the Business pages of The New York Times last week, 7/5. It included a map of the coal reserves in the US and it was frightening how vast they are. I have read that sequestration is not very secure; gas can escape and kill people, in fact has done so.
Lake NyosAE is perhaps thinking of Lake Nyos, which was a natural occurrence. Artificial sequestration has not been known to fail in the very limited instances so far tried. Deep ocean injection has been tried at beaker scale. Pressure was such that the CO2 had no choice but to be a liquid denser than water, i.e. to sink to depths where the pressure was even greater, while also slowly dissolving in the surrounding water.
The reaction with serpentinite, q.v., is also ...read more
In the Ocean?Couldn't sequestration in ocean depths mess with life down in the deep by changing the CO2 levels?

coal gasificationUse of carbon dioxide to enhance oil recovery is not sequestration! The idea with sequestration is to find a place to put the stuff where it will stay. In enhanced recovery much of the CO2 dissolves in and comes up with the recovered oil. It can be recaptured and used again, but the need for continuous supply suggests that it is not.
