COLUMBUS, OhioA new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale.
For 203 continuous hours, the Ohio State combustion unit produced heat from coal while capturing 99 percent of the carbon dioxide produced in the reaction.
Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio States Clean Coal Research Laboratory, pioneered the technology called Coal-Direct Chemical Looping (CDCL), which chemically harnesses coals energy and efficiently contains the carbon dioxide produced before it can be released into the atmosphere.
In the simplest sense, combustion is a chemical reaction that consumes oxygen and produces heat, Fan said. Unfortunately, it also produces carbon dioxide, which is difficult to capture and bad for the environment. So we found a way to release the heat without burning. We carefully control the chemical reaction so that the coal never burnsit is consumed chemically, and the carbon dioxide is entirely contained inside the reactor.
Dawei Wang, a research associate and one of the group's team leaders, described the technologys potential benefits. "The commercial-scale CDCL plant could really promote our energy independence. Not only can we use America's natural resources such as Ohio coal, but we can keep our air clean and spur the economy with jobs," he said.
Though other laboratories around the world are trying to develop similar technology to directly convert coal to electricity, Fans lab is unique in the way it processes fossil fuels. The Ohio State group typically studies coal in the two forms that are already commonly available to the power industry: crushed coal feedstock, and coal-derived syngas.
The latter fuel has been successfully studied in a second sub-pilot research-scale unit, through a...

Reducing pollution is fine, but carbon dioxide isn't pollution. It's plant food. Expensive carbon capture and sequestration technology is needed only if you believe the anthropogenic global warming, AGW, hypothesis. There's no proof of AGW. We're supposed to accept this ideology on the basis of the precautionary principle! Where else does the left apply the precautionary principle?
it’s a “faith based” initiative.
The left doesn’t observe the precautionary principle with respect to quaranteening AIDS patients, in foreign policy and national security affairs, or in fiscal and monetary policy. But we’re supposed to observe the precautionary principle for minor increases in a trace gas, carbon dioxide!
While the near infinite energy potential of thorium is largely ignored, we fret about the amount of CO2 that burning of coal releases. I am far more concerned about the health effects of fly ash and the trace radioactivity that we are spreading along with it than I am about CO2, and that is for one simple question:
What is the optimum temperature? Taken over the last several glacial cycles, on average most of Northern Europe and North America would be under hundreds if not thousands of feet of ice. For short periods it has thawed enough to grow food crops.
We also now find, thanks to a very recent project to research Antarctic ice cores that it was warmer 800,000 years ago. Yet, nobody seems very interested in why it was warmer then than now.
Are we warmer than the optimum or cooler? Who gets to decide? I am not interested in much of the frantic climate news until those simple questions are addressed.
Cut down on CO2, and you cut down on the planet's oxygen production.
These lying sphincters should be whipped within an inch of their lives, and then hung. Publicly.
Such a craven breach of the public trust is criminal on its face. But to do so in order to perpetrate a FRAUD, thus creating a cradle-to-grave control mechanism over virtually every facet of the lives of every living human being is abhorrent and vile. It is evil beyond words.
Spend 50 years "dumbing them down" with a State controlled crap education system, and then prey upon their enforced ignorance by feeding them bullsnot and soaking them for every dime you can't otherwise steal. I say they've way more than outlived their usefulness. Time to take out the garbage.
“The coal and iron oxide are heated to high temperatures...”
The article doesn’t state how the coal is heated in the first place.
Out of curiosity—how is carbon dioxide recycled? Fed to plants?
Must of been telepathy the minute I read your synopsis I was thinking the same thing. What a waste of money on a pseudo scientific premise. The only reason it may get pushed (patent patent patent) will be because we have a fascist goverment and there’s money in it for them. Let’s see what happens if this makes a mention during the inaugural. Outside of that what other application does this have ?
Won’t be good enough for the enviro-wackos including Obastard.
Not a bad idea- vent it into greenhouses.
It's engineering based on an ideology.
From the article: In the simplest sense, combustion is a chemical reaction that consumes oxygen and produces heat, Fan said. Unfortunately, it also produces carbon dioxide, which is difficult to capture and bad for the environment. So we found a way to release the heat without burning."
Their twist on the Broken Window fallacy.
You would think that a scientist would be smarter than that but then I am sure that he is being funded by a government grant to produce this technology.
How is making electricity more expensive by making the generation of the electricity less efficient going to spur the economy with jobs?
Yes you may produce a few construction jobs while you are building your white elephant of a coal plant but you are going to destroy jobs by making energy more expensive.
The best way to grow the economy is to make energy less expensive. You do that by reducing regulatory burdens that are counter productive. You do that by making it easier to build new modern generation plants and oil refineries. You do that by making it easier to license new coal mines nuclear power plants and oil fields.
This nonsense about carbon dioxide and anthropomorphic global warming is junk science and needs to be put in the dustbin of history.
Clear link between solar activity and winter weather revealed
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
They found that low solar activity can contribute to cold winters in the UK, northern Europe and parts of America. But high activity from the sun has the opposite effect.
The study helps explain why the UK has been gripped by such cold winters over the last few years: the sun is just emerging from a so-called solar minimum, when solar activity is at its lowest.
But the Global Warming Hoax prognosticators are now saying that Sun activity has nothing to do with our weather here and cutting CO2 needs to continue.
I read the press release and what I linked in comment# 1. I wrote in comment# 1: "Expensive carbon capture and sequestration technology is needed only if you believe the anthropogenic global warming, AGW, hypothesis."
Coal-Direct Chemical Looping (CDCL), might be good for reducing real pollution. I don't see a need for carbon capture and sequestration (CCS) unless manmade climate change is proven. I'm still waiting for some evidence.
Dolphins, spotted owls, baby seals, and the Dali Lama still exhale this pollutant with every breath they take. Until we find a way to exterminate these polluters, we’ll never be free of the carbon dioxide scourge.
Ideology or engineering it doesnt make a difference once you look at the bottom line.
Our economy can not afford a 35% increase in the price of electricity and still compete on the world market.
The Chinese are working very hard to reduce the cost of the energy in their economy. They have built the largest Hydro-electric dam in the world, they building a fleet of modern nuclear power plants and buy up oil leases world wide. They are aggressively expanding their access to cheap energy. We simply can not afford this kind of navel gazing idealistic non-sense that does nothing useful and raises the cost of everything.
It’s a good thing plants don’t think or liberal plants might be trying to eliminate O2!
We need to use all of our resources including coal of course, omitting wind and solar. Use our resources while developing new technologies. Cut back drastically the power of the EPA
Forget coal! It’s cold fusion that will give us all cheap energy......if only those machines can be tweaked just a tiny bit more. Some day.
Bump for later.
OTOH, the article also neglects that pulverizing coal is not energy-neutral, either...
And it says nothing about the thermal energy conversion efficiency of the process...
We're at 390ppm of CO2 and rising, starting out from about 280. Plant life drops off rapidly below 200. We are in no danger of that.
Great points. From a health perspective homosexuality is deadlier than smoking, yet it’s seen as an alternative and even positive lifestyle choice.
Does Fan have any contact info? Ignorance can be cured.
Great insights. Thackney posted a chart on electrical energy generation and its related costs. IIRC we lose in conversion about triple what we produce.
Your points are valid: there is a group called 350.org that thinks along those lines (reducing CO2 is good). There is also plant death and ice age spiral below a certain amount. But getting to that point now with our added CO2 is basically impossible.
“Out of curiosityhow is carbon dioxide recycled? Fed to plants?”
My thoughts too...if they capture the CO2, what then are they doing with it, or proposing to do with it? Maybe a huge greenhouse, creating a rainforest etc? Oh, wait...we already have that...it is our Earth’s ecosystem!
Just do what we have always done...release the CO2 to the Earth’s atmosphere...
Or another thought...a facility, a ‘living’ quarters, for these AGW leftist, zombiefied goonies to capture the CO2 they are breating out, enhancing their CO2 environment until they are overcome by the sheer joy of being deprived of O2 and saving all the rest of us from Global Warming doom!
Excellent graphs. Thanks for the link. Here is another of interest, from Vostok Station via wiki:
I am just stunned that conversion losses are 170% of gross generation. Conversion seems like a gold mine of opportunity if just 10% of those losses can be captured back you’ve just increaesd gross generation by over 15%.
Thanks for your great insights. It’s hard to sort through all the muck and get to the truth.
Billions have been spent getting it this low.
Coal, Gas, Nuclear, etc are all thermal engines and subject to the Rankine Cycle of Thermodynamics.
Our (the relatively few who are informed and aware) ability to shout over these Media-aided-and-abetted Josef Goebbels acolytes, or to re-educate the already dismally, abysmally uninformed and misinformed public, simply doesn't exist.
What is left are the two options of:
1) Lie down and take it up the Brown Snake hole...
2) Just start tracking these vicious predators wherever they live and eat, and start filling our meat lockers with their nutirent-dense organs. Hearts and livers are a must-have, and the hypothalamus, pituitary glands and adrenal glands would make a lip-smacking fun desert on some rainy afternoon!
Perhaps I'll write a cookbook to be used "After The Big One" (you knew it was coming once O'Bunghole stole the last election!) which shows people how to make tasty, filling dishes using parts harvested from wayward liberals and "Climate Change" liars.
To me that smacks of furthering ideology, not engineering prowess.
Of course it won’t be “good enough”,
because their goals aren’t even what they are stating (reducing CO2 output).
Their goals are zero energy use [by the peasants] and people shivering in the dark.
While I understand your point, CO2 is a valuable gas that has many possible uses. So there are other reasons for seperating and capturing the gas. One possible use would be to bubble through Algae tanks to produce bio-diesel or feedstocks for butanol production.
Or we could just let it go and let it feed the vegitation like it was designed to do. Just sayin’... ;)
[Out of curiosityhow is carbon dioxide recycled? Fed to plants?]
It’s shipped to a Red state and released in the dead of night.
“These lying sphincters should be whipped within an inch of their lives, and then hung. Publicly.”
No, no, you are doing it all wrong big guy. First you hang them...by their toes of course. THEN you whip them within an inch of their lives. Then you whip them some more. Then you drop them in shark infested waters...or in a hog pen if your name is Henry.
I must concur... and only wish my name were "Henry," because that sounds like alot of fun!!!
