The CCS process consists of three main steps: capture, transportation, and storage. The capture phase involves trapping CO2 emissions at their source, such as a power plant or industrial facility, before they are released into the air. There are various methods of capturing CO2, including pre-combustion capture, post-combustion capture, and oxy-fuel combustion. Once the CO2 is captured, it needs to be transported to a suitable storage site. Finally, the CO2 is stored underground in geological formations, such as depleted oil and gas reservoirs or deep saline aquifers, where it is securely contained.
There are several methods of capturing carbon dioxide from industrial and power plant emissions. Pre-combustion capture involves converting fossil fuels into a mixture of hydrogen and CO2 before combustion, allowing for the separation of CO2. Post-combustion capture, on the other hand, captures CO2 from the flue gas after the fuel has been burned. Oxy-fuel combustion involves burning fuel in an atmosphere of pure oxygen, resulting in a flue gas stream consisting mainly of CO2 and water vapor. These methods play a crucial role in reducing CO2 emissions and preventing them from entering the atmosphere.
The storage phase of the CCS process involves injecting the captured CO2 deep underground into geological formations. This prevents the CO2 from being released into the atmosphere and contributes to the long-term reduction of greenhouse gas emissions. The CO2 is stored in a secure and stable manner, ensuring that it remains contained and does not pose a risk to the environment or human health. Monitoring and verification processes are in place to ensure the integrity of the storage site and the effectiveness of the CO2 containment.
