What benefits might be offered by developing well planned CCS networks? A review of the drivers for and barriers to the coherent development of CCS networks in the UK is used to synthesise a limited set of possible network topologies. The benefits offered by each topology for UK carbon dioxide and other atmospheric emissions are estimated. Other potential benefits are considered qualitatively, and a range of uncertainties identified. The complexity of CCS networks means that addressing these uncertainties is a challenging task, and the need for a whole systems approach is evaluated. Finally, implications for CCS regulation and policy are highlighted
