As the world grapples with the escalating challenges of climate change, Carbon Capture and Storage (CCS) emerges as a crucial solution, especially for decarbonizing dominant industries such as steel, cement, and petrochemicals. The Intergovernmental Panel of Climate Change (IPCC) and the International Energy Agency (IEA) have highlighted the potential of CCS in addressing the pressing need for large-scale decarbonization. However, the widespread adoption of CCS is hindered by various challenges, including financial, organizational, technical, and governance aspects. Within this context, the research delves into the central question: "How can an evaluation framework combining both project- and policy-related factors provide a better understanding of the deployment of full-chain CCS projects, and how is it developed and implemented?"

To address this pivotal question, the study employs a multifaceted methodology. Literature research, semi-structured expert interviews, the Best-Worst Method, and a project maturity table are utilized to derive comprehensive insights. Factors influencing CCS projects are systematically categorized into six groups: political-legal, economic, social, technical, ecological, and organizational. Additionally, the research presents two in-depth case studies, ROAD and Longship, offering a practical lens into the challenges and triumphs of real-world CCS projects. The culmination of the research is a robust evaluation framework that provides a systematic approach to assess various facets of CCS projects. This framework emphasizes critical areas for resource allocation, stakeholder communication, legal clarity, and financial stability. In essence, this research not only addresses its foundational question but also crafts a multifaceted tool that stands to benefit stakeholders, guiding informed decision-making and enhancing the prospects of CCS projects' success and longevity.
