AbstractAs a developing industry, CCS in the UK can be modeled as a technical innovation system (TIS) which will likely develop in a highly non-linear fashion, relying on feedbacks from a range of system functions including R&D, market creation and learning-by-doing.Following similar work in other nations the TIS is analysed by an expert questionnaire and in-depth systems analysis. The results include input from 34 CCS experts from all areas of the TIS and allow potential weaknesses that may hamper development to be identified. An update on system functions since the survey is also then included to gauge recent developments.
