The paper provides a comprehensive overview of carbon dioxide capture and storage (CCS) technologies, focusing on the state of the art, various aspects, and their applications. It discusses the selection of CO₂ capture technology based on the type of generating plant and fuel used, with absorption being the most mature and cost-effective method. The paper also covers CO₂ separation processes, transport methods, storage options, and life cycle analysis. Key challenges include the high costs and energy penalties associated with capture, the need for robust economic incentives, and the environmental impacts of storage. The paper highlights the potential of enhanced oil recovery (EOR) and saline aquifers for CO₂ storage, while also addressing the concerns and limitations of deep ocean storage. Additionally, it explores the utilization of CO₂ in industries, agriculture, and energy production, emphasizing the importance of a portfolio of CO₂ emission reduction strategies.The paper provides a comprehensive overview of carbon dioxide capture and storage (CCS) technologies, focusing on the state of the art, various aspects, and their applications.
