Feb 1, 2024 · CO 2 geological storage (geo-storage) is a promising approach that can help to reduce greenhouse gas emissions. However, effective storage in geological underground formations requires understanding the main storage techniques and trapping mechanisms.

Feb 1, 2022 · Millions of tons of CO 2 are stored underground into geological formations annually, including deep saline aquifers. However, these geological formations have minute concentrations of organic material, significantly influencing the CO 2 containment security, fluid dynamics, and storage potential.

Mar 15, 2021 · Geological CO 2 storage can be employed to reduce greenhouse gas emissions to the atmosphere. Depleted oil and gas reservoirs, deep saline aquifers, and coal beds are considered to be viable...

Apr 13, 2023 · Underground storage of carbon dioxide (CO2) in geological formations plays a vital role in carbon capture and storage (CCS) technology. It involves capturing CO2 emissions from industrial processes and power generation and storing them underground, thereby reducing greenhouse gas emissions and curbing the impact of climate change.

Oct 23, 2024 · Calculating CO 2 storage potential is an important step in selecting target areas for CO 2 storage, which is a crucial aspect of carbon capture, utilization, and storage (CCUS) source–sink matching. At present, a variety of evaluation models are utilized to assess the potential for geo-storage media, such as coal beds, saline aquifers, oil ...

Jul 30, 2024 · Geological storage of CO2 can be achieved through a variety of technologies and can be divided into onshore, offshore, and marine storage strategies, which include storage in saline aquifers, depleted oil and gas fields, unrecoverable coal seams, hydrates, basalt, and oceans [23, 25, 26].

Storage of the carbon dioxide that is produced by burning fossil fuels is one way to avoid the damaging consequences of climate change. A range of observations suggests that geological carbon...

Jan 2, 2020 · In this chapter we will review the main processes involved in the geological storage of CO 2 and then consider the overall feasibility of storing large volumes of the CO 2 in the deep subsurface. This leads us into an evaluation of the CO 2 storage capacity and the various theoretical and practical constraints for CO 2 storage projects, globally.

5 days ago · Carbon dioxide (CO2) interacts with rock minerals due to a series of geochemical reactions affecting rock geomechanical properties. These changes in mineralogy, mechanical, and elastic properties weaken the reservoir rock and caprocks. These effects, as consequences, affect the deep saline formation’s mechanical integrity, storage capacity, storage efficiency, and permanence or safety of ...

Jan 5, 2024 · CO2 geological storage (geo-storage) is a promising approach that can help to reduce greenhouse gas emissions. However, effective storage in geological underground formations requires...
