Coal Tech Harnesses Energy Without Burning -- Captures 99% of Carbon Dioxide Produced.
34 replies, posted
[QUOTE]A 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 State’s Clean Coal Research Laboratory, pioneered the technology called Coal-Direct Chemical Looping (CDCL), which chemically harnesses coal’s 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 burns—it is consumed chemically, and the carbon dioxide is entirely contained inside the reactor.”

Game changer?
BUT THERES NO SUCH THING AS CLEAN COAL
So, where they going to put the ridiculous amount of CO2 produced?

More like never heard of again.
I may have missed it, but I don't see any mention of the temperatures achieved here. A big part is how hot it gets, because if it isn't hot enough, you can't really drive any turbines with it efficiently.
This is actually awesome if it means what I think it does.
Chances are though we'll never hear about it again.

Put it in barrels and sell it to the Italian mafia for disposal.
A bit too late, don't you think? We've already burned enough coal to shit up our planet. Now we're already moving away from fossil fuels - any innovation there is just...

Recycle it to use for one of the many industrial processes that require it or compress it like a motherfucker and store it.

Yeah if it's still being produced what are we doing with it? Guess you could feed it to plants or something. They should make a huge algae farm and just pump it through that.
Well, its not just the CO2 produced, but also the way the coal is produced. It's not a very clean way of producing energy when you literally have blow up a mountain and then fill up a lake with black sludge byproducts.

In the ground I assume.

And this maybe, although that seems weird since we'll be releasing the CO2 through those machineries instead which wouldn't make sense.

The product of many of these processes is not a gas but rather minerals containing Carbonate.

I tried to think of some witty analogy to prove just how foolish this statement was.
All I could do was stare at my screen in abject disbelief.

You realise world production of CO2 pretty much outstrips industrial needs by thousands of times over, don't you?
They were doing this at OSU?
Surprised I never heard of it.

Read the article ya poop.
[QUOTE=download;39505769]So, where they going to put the ridiculous amount of CO2 produced?[/QUOTE]Some plans call for it being pumped down empty oil wells.
Buggered if I know how they plan to make it stay there.
Compress it; bury it; dig it up in 1000 years; blast it into space.

This is good, coal is cheap and in huge supply, the better we can utilize it in an environmentally friendly way, the cheaper things like energy are since we don't artificially bottleneck our production methods.

I'm glad I'm not the only one that had that spring to mind :v:
I've always wondered why they don't put a bunch of really high tech filters on the exhaust pipes/tubes/etc on factories/cars/trucks/trains and then just bury them or something.

You seem like the sort of person who in the 1850s would have just been like, "Cotton Gin? Electric Motor? Marconi Radio? Man, that shit is never gonna be anything"
[QUOTE=NoDachi;39505773]More like never heard of again.[/QUOTE]
Oh come on it literally doesn't even make sense to say that in this case.
[QUOTE=Scrappa;39505802]Recycle it to use for one of the many industrial processes that require it or compress it like a motherfucker and store it.[/QUOTE]
In either case it'll find its way back into the atmosphere eventually.
Well good, that's one problem down.
Now about those coal mines...
