There is not any such thing !
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.
coal was discovered by two people digging and then they found coal so then they invented coal and discovered it
Coal reserves are discovered through exploration activities such as creating a geological map, then carrying out geochemical and geophysical surveys, followed by exploration drilling. Once coal is found it is mined and excavated for use.
Some disadvantages of clean coal is that it pollutes the air.

Coal has been used by humans for thousands of years, with evidence of its use dating back to ancient civilizations. The exact date of when coal was first discovered is not known, but the earliest recorded use of coal as a fuel source was in China around 4,000 years ago.

Because coal absorbs the coal molecules and that makes the water clean.

The Chinese Discovered Coal In 1423 :))))

Anthracite coal was discovered through surface outcroppings and natural erosion exposing the coal seams. Native Americans used anthracite for fuel before European settlers arrived in North America. In the early 19th century, it became an important source of fuel for heating and industry.
coal was created in 19693-06
Coal that has become diamond.
"Clean coal" primarily from the Powder River Basin, is low in sulfur content compared to other coal sources, and therefor produces less SO2 when combusted. " Clean Coal Technologies" use chemical methods of "scrubbing" SO2 from exiting flue gasses before they can be released to the environment. One byproduct of this technology is gypsum which can be used in wall board for construction.
