CBM
Methane is a powerful green house gas, as its adverse impacts are felt more intensely due to its shorter residence and higher potency in the atmosphere than carbon dioxide.
Methane is associated with coal as a by product of the coal formation process. It is trapped in coal beds and released during and after mining. This methane does cause disasters in underground coal mines.
If effectively recovered, coal bed methane associated with coal reserves and emitted during coal mining could be a significant potential source of energy.
Methane capture and its utilization from coal mines is not being undertaken in India due to:
- Lack of latest technology
- Lack of expertise and experience
- Pervasive perception that commercial viability of exploitation and utilization of Methane is doubtful.
This project is a mine-related CMM demonstration project, which is under implementation at Sudamdih and Moonidih mines of BCCL, in the Jharia Coalfield, Jharkhand State of India. The project having a duration of 5 years, was approved by the Govt. of India at an estimated cost Rs. 76.85 crores.
The different collaborators and their contributions for funding the project is given below:
