Question

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 only

(b) 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Answer 1

Correct option is (d) 1, 2 and 3

Carbon sequestration may be carried out by pumping carbon into carbon sinks of two types:

A. Natural sinks- ocean, forest, soil etc.

B. Artificial sink-depleted oil reserve, unminable mines.

So statement 1 and 2 are correct. 

And deep Saline Formations infact have highest capacity for this. So accordingly, answer is "D"
