This report provides a comprehensive overview of carbon capture and storage (CCS) technology. It begins with an executive summary highlighting the importance of CCS in mitigating greenhouse gas emissions, particularly carbon dioxide, and addresses the barriers to its implementation, such as regulatory issues and public acceptance. The report then delves into the current state of CCS, discussing various CO2 capture methods, including pre-combustion, oxyfuel combustion, and post-combustion techniques. It examines CO2 transport and storage options, and assesses the impact of CCS on the energy system and other fuels. The report further explores the technical development of CCS, highlighting advancements in CO2 scrubbers and oxy-combustion technologies. It identifies both barriers, such as cost competitiveness and storage options, and opportunities, including enhanced oil recovery and CCS in the power sector. The report concludes with a personal view on the technology and references relevant literature.
