Everything I have read suggests that clean coal is not a reality. These comments from a wiki entry appear to concur:

"Coal, which is primarily used for the generation of electricity[7], is the second largest domestic contributor to carbon dioxide emissions in the USA[8]. The public has become more concerned about global warming which has led to new legislation. The coal industry has responded by running advertising touting clean coal in an effort to counter negative perceptions, as well as by putting more than $50 billion towards the development and deployment of clean coal technologies, including carbon capture and storage. [9]. The expenditure has been unsuccessful to date in that there is not a single commercial scale coal fired power station in the US that captures and stores more than token amounts of CO2.[10]

Changing meanings of the term ‘clean coal’ and questions about motives have provoked skepticism from environmentalists. The term ‘clean coal' is often stated in quotation marks by its critics due to claims that it is a misnomer[11] and a public relations term[12]. In November 2008, NBC anchor Brian Williams described clean coal as an oxymoron as part of the network’s report on the issue[13]. However, the U.S. government employs the term in its research, as demonstrated by the U.S. Department of Energy's Clean Coal Technology Program. The DOE defines clean coal as "a new generation of energy processes that sharply reduce air emissions and other pollutants from coal-burning power plants." [14] A next evolution of the phraseology could be the redefinition of "clean coal" into "cleaner coal". This more accurately portrays the contextual benefits of the technology and applications which currently fall under the banner of "clean coal technologies"."

Maybe the better term might be cleaner coal.......and from everything I've read, its not clean enough.
