What is the major component in Coal bed Methane (CBM)?

The correct answer is Methane.

Key Points

• Methane is the primary component of Coal Bed Methane (CBM), making up about 90% to 95% of its composition.
• CBM is a form of natural gas extracted from coal beds, primarily used as an energy source.
• The extraction of CBM involves the removal of water from coal seams to reduce pressure and allow the methane to be released.
• Methane from CBM is used for residential heating, electricity generation, and as a feedstock for the chemical industry.

Additional Information

• Coal Seam Gas (CSG):
  • Also known as Coal Bed Methane, it is found in coal deposits or coal seams.
  • It is distinct from conventional natural gas found in sandstone or other rock formations.
• Formation of CBM:
  • CBM is formed during the process of coalification, where plant material is transformed into coal over millions of years.
  • Methane is generated and stored within the coal matrix and fractures.
• Environmental Concerns:
  • CBM extraction can lead to water management issues due to the large volumes of water produced.
  • Potential for methane leakage, which is a potent greenhouse gas.
• Usage:
  • CBM is used similarly to conventional natural gas for heating, power generation, and as an industrial feedstock.
  • Its utilization helps to reduce dependence on more polluting energy sources like coal and oil.
