demand arising from CCS. Therefore, we aim to identify any bottlenecks in the deployment of different CCS technologies. We evaluate a comprehensive list of technologies in terms of the three metrics, the two mentioned above, and the supply chain readiness index (SCRI). This will then enable us to highlight key areas, which require specific attention and further development. There are a range of technological alternatives which have their own relative merits and demerits. It is not our intention to promote or discount any one of them, but rather to identify issues which may limit the large-scale deployment of these technologies in the recommended time frame.
