Coal

2021-2-23Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal Mine Methane Emissions Higher

Methane emissions are a constant concern at coal mines, which vent the gas as it's emitted when coal seams are disturbed. While methane produced in some industries is captured and used to create additional energy, it's more difficult to capture from coal mines, where the gas typically makes up a tiny fraction of the overall air stream.

What is clean coal technology?

Carbon capture and storage-- perhaps the most promising clean coal technology -- catches and sequesters carbon dioxide (CO2) emissions from stationary sources like power plants. Since CO2 contributes to global warming, reducing its release into the atmosphere has become a major international concern.In order to discover the most efficient and economical means of carbon
