A qualitative analysis of key stakeholders' perception of CCS and its value chain in a Danish North Sea storage context – through a socio-economic lens

• Key carbon capture and storage stakeholder perceptions are obtained from 18 stakeholders. • Six main stakeholder topics are identified: Economics, Environment, Health and Safety, Regulation, Technology, and Social Acceptance of CCS. • General agreement about the need for carbon capture and storage, but also differences in topics perceptions. This socio-economic study explores the key considerations and challenges related to implementing Carbon Capture and Storage (CCS) in Denmark. The research leans on a content analysis based on qualitative data and utilises a methodology that includes in-depth semi-structured interviews with 18 key stakeholders, including Green NGOs, industry/emitters, trade and interest organisations, authorities, and climate experts. The interviews were conducted between 2022 and early 2023 to capture diverse perspectives and interests within the CCS domain. The research findings are grouped thematically into six main areas of interest: Economics, Environment, Health and Safety, Regulation, Technology, and Social Acceptance of CCS. The study highlights the significance of factors such as general trust in the technology, economic viability, regulatory frameworks, environmental impact assessments, safety and health concerns, technology integration, and social acceptance of CCS. The diverse perspectives and interests of the interviewed stakeholders emphasise the socio-economic complexity involved in implementing CCS in Denmark. The qualitative approach adopted in this research allowed for a narrative-based comprehensive exploration of the socio-economic dimensions of CCS. The study fills existing literature gaps within the Danish context, providing a nuanced understanding of the considerations and challenges associated with CCS. The results offer valuable guidance for policymakers, industry professionals, and researchers seeking to develop a sustainable CCS value chain in Denmark from a socio-economic perspective.
