This lecture covers various technologies for CO2 capture and sequestration, including post-combustion, pre-combustion, and oxyfuel combustion methods. It discusses the challenges, costs, and efficiency of capturing CO2 from industrial sources and power plants, emphasizing the importance of large-scale storage to make a significant impact on reducing emissions. Geological storage options and mineral carbon sequestration techniques are also explored, highlighting potential storage sites and the process of long-term carbon storage in different geological formations.
