Overview Of The Three Types Of Carbon Capture Technology

Post-combustion Carbon Capture

Post-combustion carbon capture is the most widely used method in existing power plants and industrial facilities. This technology involves capturing carbon dioxide from the flue gases emitted after the combustion of fossil fuels. The captured carbon dioxide is then separated, treated, and compressed for transportation and storage in suitable geological formations underground. Post-combustion carbon capture allows for retrofitting existing power plants and is a significant step towards reducing greenhouse gas emissions.

Pre-combustion Carbon Capture

Pre-combustion carbon capture involves capturing carbon dioxide before the combustion process takes place. In this method, fossil fuels, such as coal or natural gas, are converted into synthesis gas (syngas) through high-temperature gasification. The syngas is then processed to remove impurities like sulfur and mercury, and the carbon dioxide is separated from the hydrogen. The resulting hydrogen can be used as a clean fuel, while the carbon dioxide is captured and stored underground. Pre-combustion carbon capture is commonly used in industrial processes and has the potential to minimize carbon emissions from various sectors.

Oxy-fuel Combustion Systems

Oxy-fuel combustion systems involve burning fossil fuels in an atmosphere of pure oxygen rather than air. By eliminating the nitrogen present in air, oxy-fuel combustion produces a carbon dioxide-rich flue gas, facilitating easier capture and storage of carbon dioxide. The flue gas is cooled, and the captured carbon dioxide is separated and compressed for storage. Oxy-fuel combustion systems have the advantage of being retrofittable to existing power plants, making them a promising option for reducing emissions from the energy sector.

These three types of carbon capture technology offer different approaches to capturing and storing carbon dioxide emissions. Each method has its advantages and application areas, making them essential tools in the fight against climate change.
