The determination of carbon dioxide storage capacity and the selection and characterisation of potential sites for CO2 storage are key issues in taking Carbon Capture and Storage (CCS) forward. Most current storage capacity estimates are imperfect and there is a need for more understanding of the issues and more general agreement on assessment methodologies for the selection of an appropriate site to store carbon dioxide safely and securely for thousands of years and longer. This paper provides an overview of the various scales of site selection and the different levels of storage capacity Previous HitestimationNext Hit and how these can be integrated. The natural variability and geological, engineering and economic complexity of any potential CO2 storage site means that each site needs to be assessed individually; however, a similar workflow can be applied to most site evaluations, and the processes for these analyses can be made to be iterative. CCS researchers from the Carbon Sequestration Leadership Forum (CSLF), the US Department of Energy (DOE) Regional Carbon Sequestration Partnerships and the Australian Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) have been engaged in developing consistent and systematic methodologies that can be used in assessing and classifying CO2 storage volumes of potential storage sites. Such methodologies provide a uniform language that is understandable to (and usable by) the scientific community but can also be accepted by industry and the financial community. In addition, the key issues and challenges in storage capacity Previous HitestimationTop and storage site selection are highlighted and methodologies to address the issues and to meet those challenges are presented.
