Explanation: Carbon sequestration or carbon dioxide removal is the long-term removal, capture or sequestration of carbon dioxide from the atmosphere to slow or reverse atmospheric CO2 pollution and to mitigate or reverse global warming. The carbon that is captured can be stored in geological formations such as deep saline aquifers, basalt formations, unmineable coal seams and depleted oil or gas reservoirs. Hence all the given options are correct.
Educational Objective: To learn various methods that can be employed to reduce the release of various Greenhouse Gases.

Potential Sites for Carbon Sequestration
1) Abandoned and uneconomic coal seams
2) Depleted oil and gas reservoirs
3) Subterranean deep saline formations
All three options mentioned in the question can be potential sites for carbon sequestration. Let's discuss each option in detail:
1) Abandoned and uneconomic coal seams:
- Abandoned and uneconomic coal seams refer to coal mining sites that are no longer in use or economically viable. These sites can be repurposed for carbon sequestration.
- The process of carbon sequestration involves capturing carbon dioxide (CO2) emissions from industrial sources and storing them underground.
- Abandoned coal seams provide suitable geological formations for the storage of CO2 due to their depth, porosity, and permeability.
- CO2 can be injected into the coal seams, where it is adsorbed onto the coal matrix and stored securely over long periods of time.
- This method not only helps in reducing CO2 emissions but also enhances the recovery of methane, a potent greenhouse gas, from the coal seams.
2) Depleted oil and gas reservoirs:
- Depleted oil and gas reservoirs are underground formations that have been depleted of their hydrocarbon resources.
- These reservoirs can be repurposed for carbon sequestration as they offer suitable geological formations for CO2 storage.
- The CO2 can be injected into the reservoirs, where it is trapped by a combination of structural trapping, residual trapping, and solubility trapping mechanisms.
- The reservoirs provide a secure and permanent storage option for large quantities of CO2.
3) Subterranean deep saline formations:
- Subterranean deep saline formations refer to underground formations that contain saline water.
- These formations can also serve as potential sites for carbon sequestration.
- CO2 can be injected into the saline formations, where it is stored in the form of dissolved CO2 and mineral carbonates.
- Saline formations have immense storage capacity and can potentially store large amounts of CO2 over geological timescales.
Conclusion:
In the context of mitigating global warming, all three options mentioned in the question - abandoned and uneconomic coal seams, depleted oil and gas reservoirs, and subterranean deep saline formations - can be potential sites for carbon sequestration. These sites provide suitable geological formations for the secure and permanent storage of CO2 emissions, helping to reduce the impact of anthropogenic emissions on climate change.
