With reference to two non-conventional energy sources called ‘coal bed methane’ and ‘shale gas’, consider the following statements:
1. Coal bed methane is the pure methane gas extracted from coal seams, while shale gas is a mixture of propane and butane only that can be extracted from fine-grained sedimentary rocks.
2. In India abundant coal bed methane sources exist, but so far no shale gas sources have been found.
Which of the statements given above is/are correct?
Pick an option to check yourself. The answer stays hidden until you attempt.
• Correct Answer: D
• Neither statement is correct: shale gas is mainly methane (not just propane/butane), and India has identified shale gas in Cambay, KG, Cauvery basins.
• CBM is primarily methane from coal seams; India has both CBM and shale gas potential.
