of CCS because only dehydration and compression would be required at the capture stage (see Section 3). An analysis of these high-purity sources that are within 50 km of storage formations and that have the potential to generate revenues (via the use of CO2 for enhanced hydrocarbon production through ECBM or EOR) indicates that such sources currently emit approximately 360 MtCO2 per year. Some biomass sources like bioethanol production also generate high-concentration CO2 sources which could also be used in similar applications.
The distance between an emission location and a storage site can have a significant bearing on whether or not CCS can play a significant role in reducing CO2 emissions. Figure
TS.2a depicts the major CO2 emission sources (indicated by dots), and Figure TS.2b shows the sedimentary basins with geological storage prospectivity (shown in different shades of grey). In broad terms, these figures indicate that there is potentially good correlation between major sources and prospective sedimentary basins, with many sources lying either directly above, or within reasonable distances (less than 300 km) from areas with potential for geological storage. The basins shown in Figure TS.2b have not been identified or evaluated as suitable storage reservoirs; more detailed geological analysis on a regional level is required to confirm the suitability of these potential storage sites.
