Abstract

Abstract The COACH project was an EU-China collaboration funded by the EU’s FP7 R&D programme to assess the potential for a CCS demonstration project in China. The Jing-Jin-Ji Region of North-Eastern China is a major contributor to China’s CO 2 emissions profile with large stationary sources currently contributing annual emissions of nearly 350 million tonnes CO 2 per year, of which approximately 300 million tonnes CO 2 has the potential to be captured and stored annually. Two scenarios for a CCS demonstration project located in the onshore section of the Bohai Bay region in Shandong Province in the North East of China were assessed in this study. Capture studies considered a polygeneration scenario while scoping studies were performed of storage potential within the onshore Bohai Bay area. Size scales of <1 Mtonnes/year (c. 5 million tonnes storage capacity) and >1Mtonnes/year (c. 100 million tonnes storage capacity) were considered. Introductory screening was performed for four areas to review their potential for development for CO 2 storage. These included two oilfield provinces, a regional saline formation and a coal mining area. A preliminary risk assessment was prepared covering both technical and non-technical issues. Order of magnitude costs likely to be incurred in implementing a CCS demonstration project were assessed. These included estimates of the cost of capture and conditioning of the CO 2, transportation to a storage site and the storage of the CO 2 in a geological formation. The cost of capture was expressed relative to a reference case comprising an IGCC without CCS. A single product, electricity, was considered. Storage costs were assumed to arise from appraisal (saline formations and coal mining areas), wells (new CO 2 injectors and remediation or upgrading for existing wells) and monitoring.
