So-called "clean" coal plants: are they really? Here's one example of why they aren't...the left-over ash. Even if the stack discharge of CO and other greenhouse gases is minimal, there is still the huge problem of disposing with the leftover ash...

What are they going to do to clean this up? Vacuum this gunk up for the next 1000 years? My guess is they will do nothing about it...

You have a single accident at one facility of hundreds so you're going to condemn a whole industry for it? If you wanted to set that type of criteria down we could condemn every industry that has ever existed. This is the result of either a) poor engineering, b) poor maintenance or C) a combination of both.

Not sure about bituminous ash but locally anthracite ash is considered clean fill and they actually are doing quite a few good things with it. We have culm banks that have been sitting here for most of century, this is the waste leftover after coal has been processed and contains mostly rock. What they have been doing is reprocessing the bank to extract what fuel is left, what they exctract is suitable for burning in co-gen plants. The site where the bank is at is contoured and topped with soil, the ash is used to fill in old stripping holes also contoured after it is filled.

Same thing for Bituminous. We actually sell the majority of our ash to a cement company and road construction company with the rest being used as base structure in landfills..........Try again Bud......

....also mentioned in that article is the old "coal ash contains heavy metals and other toxins".... What they fail to mention is that it's slightly elevated above the concentrations in your average pile of dirt.

'clean coal'
isn't that the greatest oxymoron of our time?
Just hearing the term bandied about makes my skin crawl.

Oxymoron it is not, clean coal technology is here and has been. The coal plants of today is far less a polluter than those built 30 years ago. Clean coal technology is not something that has just burst onto the scene but instead has been a evolving process over the last 30 years with newer and better technologies every day. Today's coal plant produces far less pollution. From 1997:

DOE - Fossil Energy Techline: Florida Clean Coal Plant Showcases Clean, Efficient Power for 21st Century



That's "The Reality", and that technology was employed in 1997. Those commercials you see on TV are about as bogus as it gets, nothing but propaganda.

What those commercial refer to is the inability of plants to capture CO, this not necessarily a "polluter" but instead is what is blamed for global warming. Plants capable of this are about to be tested, I know there is at least one large scale test that will be performed in Wyoming shortly. Capturing the CO is possible, it's the storage of it that is the major hurdle. I beleive it's the plant in Florida mentioned in the above article that is also capable of carbon capture but they have not tested it yet becuse of legal issues with the state of florida that have no been worked out yet... It's here, don't be fooled by lies.

One of the paradoxs of clean coal is that those groups who cry for emission reductions also prevent the building of new plants that, when built, will in fact reduce emissions from an old plant. Often to the point that the old plant that is licensed and permitted too operate long into the future has more emissions then the new and upgraded plants would have combined. And in this case they prevent the building of transmission lines that will allow the movement of wind generated energy from a constrained area.

Remember the Exxon Valdez? Coal ash is not the pollutant that oil is when it's spilled into waterways. It's nothing compared to a dam bursting, and it's a minor blip compared to a nuclear accident. Coal is the world's most abundant source of fossil fuel. It's not the perfect solution, but without it we'd be in the dark.

Im am grateful for being alive thanks to coal mining. Coal Mining provided my grandfather a job that fed his wife and two kids. One of his two kids his daughter she met my late father who practice medicine for the coal miners. Coal mining has been going on since it founding days.
My grandmother who is still living in here 70's lives off my late grandfather Coal Miner Pension and she has never drove a car in her life and lives in a very remote area but survives oday's world expenses due to my grandfather contribution to the coal mining.
God gave man the ability to use his brain to use the earth resources.
More restrictions we put on American companies gives them more reason to do business over seas meaning loss of jobs
