||This report provides an overview of the Thermal Power with CCS – Generic Business Case Project, summarising the three major reports (Site Selection Report, Plant Performance and Capital Cost Estimating, and Plant Operating Cost Modelling). The purpose of this project was to compare the feasibility and costs of a single design of large gas fired power plant fitted with CCS, at a range of sizes (modules of 1x 600 MWe to 5x 600 MWe), in five separate UK regions. For each region an optimal site was selected to establish the costs and feasibility of the chosen plant design. A set of common values, limitations and selection criteria were applied in the site selection process including:
Through this approach, the project was designed to enable regional comparisons for the type of plant selected and incorporating the design criteria/values applied commonly across each of the regions. Hence, the reader will see in the report direct comparisons between regions – these statements relate specifically to the findings from the cases shown and the design criteria considered. It is possible that other plant types and other design criteria considered by different organisations may lead to different, and also valid, conclusions.
- Approach to risk – for investability, a lower risk approach was taken.
- Approach to public safety – this affected CO2 pipeline routings for example.
- Scale (upto 2-3 GWe), to be comparable with nuclear scales of operation. This impacted, for example, CO2 store selection decisions while some sites were unable to host the largest scales of operation tested by the project.
- Ability to gain consents such as planning permission.
- Public acceptance – this impacted, for example, site locations near areas of high population in particular since the plant size is extremely large; and CO2 pipeline routing choices.
