In March 2010, the Scottish CCS (Carbon Capture & Storage) Consortium began an extensive Front End, Engineering and Design (FEED) study to assess what would be required from an engineering, commercial and regulatory, perspective in order to progress the CCS demonstration project at Longannet Power station in Scotland through to construction. The study yielded invaluable knowledge and the resulting material are available for download here. This section of the report provides a summary of key decisions and design changes made during FEED that have resulted from the development of the End-to-End solution and the design works conducted by each of the Consortium Partners. The information described in this section captures the design decisions and changes that have had the most prominent impact on the End-to-End Basis of Design. For each key design change/decision, the background, options considered and the final outcome is described. The ScottishPower CCS Consortium Decision Register can be found in PDFs . The appropriate summary section from the Feed Close Out Report can be downloaded as a PDF (Key FEED decisions.pdf). The main text of the FEED Close Out Report, together with the supporting appendix for this section can be downloaded as PDF files.
