The capture and geological storage of CO2 (CCS) is widely recognized as a key technology to reduce Greenhouse Gases (GHG) emissions. Developing a successful decarbonization plan via CCS involves identifying the source of emission, creating a commercial Carbon Capture and Storage network to transport captured CO2, and injecting it into a suitable geological formation. This work presents a multistage data evaluation process carried out to provide a plan for the development of a full-chain industrial CCS cluster. For this purpose, we identified an industrial emission hub in Asturias region (Spain) as a large CO2 emission source and priority decarbonization target. Using publicity available information on storage structures, we applied a multi-staged source-to-sink assessment methodology to select the most suitable site for the storage of the captured CO2. This methodology involves testing multiple scenarios to provide a sensitivity analysis of the selection of the best candidate, the Iglesias-UT structure. Finally, the selected storage site was re-evaluated in more detail by interpreting the petrophysical properties for analyzing the uncertainties of the structure.
