Which of the following Indian state has largest resouces of Coal bed Methane (CBM)?

The correct answer is Jharkhand.

Key Points

• Jharkhand has the largest resources of Coal Bed Methane (CBM) in India.
• The state holds significant coal reserves, which are a primary source for CBM extraction.
• Major CBM fields in Jharkhand include the Jharia and Bokaro coalfields.
• The state’s CBM resources are estimated to be around 274.5 billion cubic meters.
• Efforts are underway to commercialize CBM extraction in Jharkhand to enhance energy production and reduce dependence on conventional fossil fuels.

Additional Information

• Coal Bed Methane (CBM)
  • CBM is a form of natural gas extracted from coal beds, commonly referred to as "sweet gas" due to its lack of hydrogen sulfide.
  • It is considered an unconventional source of natural gas because it is stored in the coal seams and extracted through drilling.
  • CBM is a clean energy source with lower carbon emissions compared to conventional coal usage.
  • The gas primarily consists of methane, which is a potent greenhouse gas if released into the atmosphere but burns cleaner than coal.
• Extraction and Utilization of CBM
  • CBM extraction involves drilling wells into coal seams and reducing pressure to release the gas.
  • It can be used for power generation, as a domestic fuel, and as a feedstock for the chemical industry.
  • India’s Ministry of Petroleum and Natural Gas oversees CBM exploration and production activities.
  • The government has been encouraging private sector participation to boost CBM production.
• Environmental and Economic Impact
  • CBM production can help reduce methane emissions from coal mining activities, thus mitigating its environmental impact.
  • It provides an alternative energy source that can help diversify the energy mix and reduce reliance on imported natural gas.
  • CBM projects can generate employment and contribute to the local economy through infrastructure development.
  • However, the extraction process must be managed carefully to avoid groundwater contamination and land subsidence.
