Using the energy in oil shale without releasing carbon dioxide in a greenhouse world
WASHINGTON, Sept. 28, 2011 — New technology that combines production of electricity with capture of carbon dioxide could make billions of barrels of oil shale — now regarded as off-limits because of the huge amounts of carbon dioxide released in its production — available as an energy source. That’s the topic of the latest episode in the American Chemical Society’s (ACS) award-winning “Global Challenges/Chemistry Solutions” podcast series.
Adam Brandt, Ph.D., notes in the podcast that almost 3 trillion barrels of oil are trapped in the world’s deposits of oil-shale, a dark-colored rock laden with petroleum-like material. Brandt and colleague Hiren Mulchandani are at Stanford University.
The United States has by far the world’s largest deposits in the Green River Formation, which covers parts of Colorado, Utah and Wyoming. The domestic oil shale resource could provide 1.2 trillion to 1.8 trillion barrels. But concerns over the large amounts of greenhouse gases — mainly carbon dioxide — released by current methods prevent many companies from trying to extract oil from shale.
Brandt’s answer is EPICC — a self-fueled method that generates electricity, as well as the heat needed to produce that electricity from shale. The report, which appears in ACS’ journal Energy & Fuels, describes how EPICC could generate large amounts of electricity without releasing into the atmosphere carbon dioxide from burning the shale. That carbon would be captured and stored underground as part of the production process.

Hmmmn.
Must put politically corrupt (er, correct) thinking hat on.
Coal in ground (cheap and easy to get at) is “bad” because when burned to make (cheap and convenient) electricity above ground, the coal will release CO2 into air to allow all plants and plankton on earth to grow faster and stronger in less time.
Oil shale in ground (difficult to get at and very expensive to process from low density rock sources) is “good” because it can be converted (with very expensive and untested technology with unproven methods) very far underground to create a little bit of (very expensive) electricity above ground while forcing the released CO2 back into the rocks (by re-pressurizing with very expensive process energy and massive pumping energy?) …..
Exactly backasswards – as is almost all associated with today’s EPA and Washington bureacrazies: We can and should produce inexpensive electricity the most efficient way possible (by burning coal now, nuclear fission and fusion later) while reserving the underground oils and oil-derivatives for their unique chemicals progression towards plastic and transportation energy sources. Both of with oils are good for! But NOT for making electricity.
Methinks the American Chemical Society (chartered by Congress and with (very expensive) headquarters in Washington DC!) is looking to butter up Obama’s EPA for more funding while the funding is still good.
But skeptics are evil deniers because they are claimed to be funded by the evil oil companies.
Using real science to combat a non-existant problem is not scientific but sheer stupidity and proof that science is furthest from assessment process.

There may be some confusion here. At least there was confusion in my mind until I looked it up just now!
“Shale oil”, oil found in shale deposits, is not off limits. It’s being produced enthusiastically, and so far the EPA hasn’t done anything serious to stop it.
The article is talking about “oil shale”, which is not crude oil at all but a petroleum precursor called kerogen. This requires many extra stages of heating and chemical processing before it can enter the usual refinery.”
=====
Pretty much correct I believe. There are a wide variety of “oil shales”. Some are commercially exploitable using current technology — either by extracting the oil or by burning the oil while it is still in the source rock. There was some commercial oil production in Ontario in the 19th Century from a hydrocarbon rich bed in the Utica Shale.
The Green River oil shale gets a lot of attention because there is so much of it — hydrocarbons thought to be greater than the entire oil reserves of the planet … But the energy is incredibly difficult to extract. Imagine bricks that have somehow had candle wax injected into the pores. No one really knows how to get the energy out economically. Much less what to do with the waste rock. Barring some wondrous new technology, coal is much easier to extract and — difficult as it may be to believe — probably LESS of an environmental disaster than exploiting the Green River shale oil with current technologies would be. That’s saying a lot.
I know little about the extraction process for getting kerogen out of shale, but assume it takes lots of heat. Nuclear power plants produce lots of heat….
That’s the beautiful thing about the precautionary principle — ‘Maybe the doomsday scenarios about XXXX are true, so we should just go ahead and do everything we can to make sure XXXX doesn’t happen’ — it shortcuts all discussion of the facts, dismisses a careful consideration of the risks and the trade-offs and takes you straight into environmental activism. Nobody has to think too much and they get to feel better about themselves.
If AGW is a hoax (as I believe it is) then this research is pointless; on a par with discovering how many angels can dance on the head of a pin.
I would guess that their process is similar to an Integrated Combined Cycle with coal gasification and CO2 sequestration. (A coal system is shown as an example of what I suspect the oil system will be like.)
http://en.wikipedia.org/wiki/Integrated_gasification_combined_cycle
The example in the above shows a 310 mWe plant, but glosses over the fact that it will consume 50 mWe just to run the air liquefaction compressors. (How did you think they are going to separate the O2 from the N2?) Good luck handling those 2,100 Tons per Day of liquid O2. But the Ar byproduct will have some value to welding supply companies.
(Argon constitutes 9,340 ppmv and is the third most common gas in the atmosphere. CO2, on the other hand is only 390 ppmv. However, the unintended consequence is that the sudden abundance of Ar would probably ruin the market. For example, “way back when” sulfur mines used to be profitible. Now, elemental sulfur is “free” as a waste product from oil refining, etc.
http://folc.ca/sulphur_storage/waste_sulphur.htm)
Having had real world experience with fossil fuel power sources, I would guess that the black box efficiency (BTU/ coal in: mWe available to the grid) of the above example is going to be on the order of 30% to 50% less than a modern coal fired plant. Plus higher capital costs and higher maintenance costs will make the $/kWhr perhaps 50% more expensive. For a hoax.
I haven’t found the actual figures. If one of you Gentle Readers has data from the operating demonstrations, I would welcome the knowledge.

The energy companies and their shareholders will decide if this is worthwhile economically. When the politicians and bureaucrats get involved, who knows?
Here we go:
IOW, another pipe dream that won’t work without a thumb on the scale.
I work at a facility (in the Air Program, of all places!) with numerous point sources of emissions (boilers, water heaters, landfills, etc.) that cause this facility to be a major emitter of GHG’s under the new EPA GHG Tailoring Rule. And – we must report our CO2 emission in “Carbon Equivalents” by close of busines TOMORROW September 30, 2011!!!! See the EPA website:
http://www.epa.gov/climatechange/emissions/ghgrulemaking.html
We are not being charged emission fees (or fines) for this reporting year of 2011 – but I just thought you all would like to see, that there are reporting requirements in place – right now – in real time – for those above the emission thresholds.
If you open the EPA website, and root around you will see the convoluted and confusing “GHG Reporting Tool” that we must use to report emissions – a Beta test that lends itself to engineers and savvy consultants but is very confusing to even us veteran “Air Heads” (read: Air Program veterans). I guess what I am trying to impart to everyone, is that this is not some future issue – IT IS HAPPENING RIGHT NOW.

Totally ignores the herd of elephants in the room!! 1KG of shale has less energy in it than 1KG of camel dung. Shale is simply not viable as an energy source as it takes nearly as much energy to extract as you get from it.
The same was true of oilsands 30 years ago but technology has changed that. Technology will change the dynamics of oilshales too.
I knew there was a reason for Canada.
I just had an idea. Why don’t we let the free market decide? Nah, that’ll never work in a society run by “busy bodies and do-gooders.” Sorry……
Why not a technology like the one being developed by Joule? http://www.jouleunlimited.com/news/2011/joule-named-2012-technology-pioneer-world-economic-forum

Hey, RoHa, have you seen Mt. Rushmore from Canada?

Article title is misleading – there’s a big difference between a process that doesn’t create carbon dioxide and one that doesn’t release it.
