Geologic Sequestration is thought to have the largest potential for near-term application in carbon sequestration.

Geologic Sequestration: The Most Promising Method
Geologic sequestration, often considered the most effective method for carbon capture and storage in the near term, involves the long-term storage of carbon dioxide (CO2) in underground geological formations. Here's why it stands out:
1. Established Techniques
- The technology for geologic sequestration is well-developed and has been utilized successfully in various industrial applications.
- Techniques like Enhanced Oil Recovery (EOR) already incorporate CO2 injection, demonstrating operational viability.
2. Large Storage Capacity
- Geologic formations, such as depleted oil and gas reservoirs, saline aquifers, and unmineable coal seams, have the potential to store vast amounts of CO2.
- Estimates suggest that the global capacity for geological storage could exceed several thousand gigatons, making it a feasible long-term solution.
3. Immediate Impact on Emissions
- Geologic sequestration provides a way to capture emissions from existing fossil fuel power plants and industrial processes.
- By retrofitting these facilities with carbon capture technologies, significant reductions in atmospheric CO2 can be achieved almost immediately.
4. Safety Considerations
- Natural geological formations have safely contained hydrocarbons for millions of years, supporting the notion that CO2 can be stored securely.
- Regulatory frameworks and monitoring systems can be established to ensure the integrity of storage sites.
5. Economic Viability
- The development of carbon markets and incentives for carbon capture technologies can enhance the economic attractiveness of geologic sequestration.
- Investments in this area can lead to job creation and technological advancements that support a transition to a lower-carbon economy.
In conclusion, geologic sequestration presents a practical and scalable approach to mitigating climate change effects, making it a leading candidate for immediate implementation in carbon management strategies.
