Types of Carbon Capture Technologies

Carbon capture technologies play a crucial role in mitigating climate change by removing carbon dioxide (CO2) from the atmosphere or preventing its release into the atmosphere. These technologies capture CO2 from various sources, including power plants, industrial facilities, and even directly from the air.

There are different types of carbon capture technologies, each with its own advantages and disadvantages.

Pre-Combustion Capture

Pre-combustion capture involves capturing CO2 before it is released into the atmosphere during the combustion process. This technology is typically used in power plants that utilize fossil fuels like coal or natural gas. In pre-combustion capture, the fuel is first converted into a mixture of hydrogen and carbon monoxide.

The carbon monoxide is then oxidized to CO2, which is then captured and stored or utilized.

Pre-combustion capture can achieve high CO2 capture rates, often exceeding 90%.
The captured CO2 is relatively pure, making it suitable for storage or utilization.
The technology can be integrated into existing power plants with minimal modifications.

Disadvantages of Pre-Combustion Capture

Pre-combustion capture requires significant energy input, which can reduce the overall efficiency of the power plant.
The technology can be complex and expensive to implement.
There are concerns about the safety and environmental impact of storing large quantities of CO2.
