Burning of coal, a fossil fuel is one of the principal causes of climate change and global warming.
"Clean coal" or "Green coal" is a theory that we can capture all the pollutants including sulphur dioxide and carbon dioxide from coal as it is burnt and store them, instead of releasing them as greenhouse gases.
The carbon dioxide will then be pumped underground into vacant spaces where oil and natural gas used to be. This will be known as "carbon sequestration".
Countries that rely on coal for their economies and electricity generation (Australia, for one) are hoping that clean coal will let them continue using and exporting "clean" coal without the carbon pollution attached.
Unfortunately there are no examples of successful coal "cleaning" so far.
Many environmentalists believe that the term clean coal is misleading: "There is no such thing as 'clean coal' and there never will be. It's an oxymoron" (Sierra Club director, Dan Becker).
Complaints are:
As an example of the difficulties involved, Australia's coal-fired power stations produce 260 trillion liters of carbon dioxide every day (260,000,000,000 liters). The energy required to compress and sequester this would use massive amounts of the power generated by the "cleaned" coal.
Clean coal is a term for technology (Clean coal technology) that mitigates emissions of carbon dioxide (CO2) and other greenhouse gasses that arise from the burning of coal for electrical power. It reduces the harmful emissions caused by the burning of fossil fuels.
coal that is burned with technology that cuts the amount of soot and sulfur dioxide emitted
Some disadvantages of clean coal is that it pollutes the air.
It is very important to use clean coal technology. The pollutants from burning coal causes health problems as well as environmental problems. The clean coal technology cuts back on these pollutants and provides a cheap form of energy.
Water vapor
There is not any such thing !
THERE IS NO SUCH THING AS CLEAN COAL, and people who say that there is are just trying to fool you. Burning coal always releases carbon dioxide, nitrogen oxides, sulfur oxides, and other dangerous and noxious pollutatnts.
There is no such thing as green coal.

Some clean coal technology that reduces the emissions of green house gas, includes the 'Oxy Fuel CCS Power Plant'. This technology filters the and clean the carbon dioxide before storing in in the underground layer. This technology was invested by the government officials to tackle the global warming issues.
