Q100.
In the context of mitigating the impending global warming due to anthropogenic emissions of carbon dioxide, which of the following can be 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:
Answer
D
Explanation
Carbon sequestration is the process involved in carbon capture and the long-term storage of atmospheric carbon dioxide. Geological sequestration involves the storage of CO2 underground in depleted oil and gas reservoirs, saline formations or deep, un-minable coal beds. All three — abandoned coal seams, depleted oil and gas reservoirs, and subterranean deep saline formations — are potential sites for geological carbon sequestration.
