This paper presents results from the first round of an extensive on-line Delphi survey of experts in the field of carbon dioxide capture and storage (CCS). Questions related to key drivers of energy technology in the UK, capture and engineering, CO 2 transport, storage, risks and leakage, monitoring and remediation, costs and economics, incentives, regulation, international context. The survey has constructed a comprehensive picture of expert opinion on the current status of CCS in the UK from across the CCS and related energy supply community. The results contribute to understanding how large-scale deployment of CCS might be realised in the UK and the challenges associated therein. The survey revealed that key barriers to implementation of CCS are currently a lack of long-term policy framework in the UK and costs. There remain aspects of the process that require further investigation but until the technology is adopted on a commercial scale, in the context of a commitment to significant reductions in CO 2 emissions across all demand sectors, it is neither possible nor appropriate to predict the details of how the process will evolve.
