Clean Coal Technology Market: Information by Type

Mar 17, 2021Since coal is rich in carbon, its combustion leads to the production of energy. Coal is primarily used for electricity and power generation and is categorized into four different types depending on the carbon, oxygen, and hydrogen content present in it. The higher the carbon content, the greater the energy contained by the coal.
