Cảbon Capture and Sequestration Methods

A technique employed to address climate change is carbon capture and sequestration (CCS). This process entails capturing carbon dioxide (CO2) emissions at their origin and securely storing them to prevent their release into the atmosphere. Various methods exist for capturing and sequestering CO2:

Geological Sequestration

The prevailing approach involves injecting carbon dioxide (CO2) into deep geological formations, such as depleted oil and gas reservoirs or saline aquifers. This process involves compressing CO2 into a liquid, transporting it to the injection site, and then pumping it into porous rock formations located hundreds of meters below the surface. Subsequently, the CO2 disperses within the formation, with some dissolving in fluids. Over time, mineral reactions occur, converting the CO2 into solid carbonate minerals, thereby permanently sequestering the carbon dioxide. Vigilant monitoring is essential to ensure the CO2 remains securely trapped underground.

Ocean Sequestration

Injecting CO2 into deep ocean waters is another approach, wherein the gas dissolves and integrates with seawater. Nevertheless, this technique is currently in the experimental stage, and there are environmental apprehensions regarding its potential impact on marine ecosystems.
