| In the context of mitigating the impending global warming due to anthropogenic emissions of carbon dioxide, which of the following can be the potential sites for carbon sequestration? |
| 1. Abandoned and uneconomic coal seams |
| 2. Depleted oil and gas reservoirs |
| 3. Subterranean deep saline formations |
| Select the correct answer using the code given below: |
A) 1 and 2
B) Only 3
C) 1 and 3
D) 1, 2 and 3
Correct Answer: D
Solution :
Exp. [d] Capturing \[C{{O}_{2}}\]from the major stationary sources and its storage into deep geological formations is considered as a potential mitigation option. Geological storage of \[C{{O}_{2}}\] can be undertaken in a variety of geological settings in sedimentary basins. The options for \[C{{O}_{2}}\]are as follows ? Depleted oil and gas reservoirs ? Use of \[C{{O}_{2}}\]in FOR ? Deep unmineable coal seams/enhanced coalbed methane E25M) recovery ? Oceans ? Deep unused saline water-saturated formations ? Other geological media are basalts, shales, and cavities ? Subterranean deep saline formations
