Precombustion capture is a process in which carbon dioxide (CO2) is separated from a fuel source before it is burned. This is a key technology in the development of post-combustion capture and oxy-fuel combustion capture, which are methods for capturing CO2 from flue gases after combustion. The primary goal of precombustion capture is to remove CO2 from the fuel gas at a high pressure and before it enters the combustion chamber. This often involves converting the fuel into a mixture of hydrogen and CO2, typically through a process called gasification or steam reforming. The CO2 can then be separated from the hydrogen, which can be used as a clean fuel source for power generation. The separation of CO2 from the fuel gas is usually achieved using various technologies such as physical or chemical absorption, membranes, or cryogenic separation. The captured CO2 can then be transported for geological sequestration or utilized in other industrial processes. Precombustion capture is considered an efficient method for CO2 reduction as it targets the removal of CO2 at an earlier stage of the energy production cycle, potentially leading to lower energy penalties compared to post-combustion capture. Research and development continue to focus on improving the efficiency and cost-effectiveness of precombustion capture technologies.
