ASSESSING THE CARBON SEQUESTRATION POTENTIAL IN SOUTHWESTERN SWEDEN A comparative study of igneous rock from Greenland, Iceland, and Sweden to evaluate the carbonatization potential of the Billdal area, SW Sweden
The main purpose of this study is to investigate the potential of geological Carbon Capture and Storage (CCS) in SW Sweden using an innovative technique which mimics Earth's natural way of regulating the global carbon cycle by turning CO2 gas into carbonate minerals. To achieve this, comparativ...
