The report highlights the importance of Carbon Capture and Storage (CCS) hubs and clusters in reducing carbon emissions in Europe. CCS is a technology that captures carbon dioxide emissions from industrial processes and stores them underground, reducing the amount of CO2 released into the atmosphere. The report addresses common questions about CCS, including what CCS hubs and clusters are, why they are important, and how they can support the development of European EOR operations and enable cost-effective decarbonization. The report also discusses the availability of storage resources in Europe and the potential for CCS hubs and clusters to reduce CO2 supply risk. Overall, the report emphasizes the importance of CCS in the fight against climate change and the role that CCS hubs and clusters can play in enabling its widespread adoption.
