Carbon capture and storage (CCS) technologies are crucial for mitigating climate change by capturing carbon dioxide (CO2) emissions from industrial sources and storing them underground. These technologies can significantly reduce the amount of CO2 released into the atmosphere, helping to limit global warming and its associated impacts. CCS involves capturing CO2 from power plants, industrial facilities, and other sources, transporting it to a storage site, and injecting it deep underground into geological formations. The CO2 is then permanently stored, preventing it from contributing to climate change. There are several different CCS technologies, including pre-combustion capture, post-combustion capture, and oxy-fuel combustion. Pre-combustion capture involves converting fuel into a mixture of hydrogen and CO2 before combustion, making it easier to separate the CO2. Post-combustion capture involves capturing CO2 from the flue gas after combustion, using chemical solvents or other methods. Oxy-fuel combustion involves burning fuel in pure oxygen instead of air, producing a concentrated stream of CO2 that can be easily captured.
