The IEA Greenhouse Gas R&D Programme (IEAGHG), on behalf of the Global CCS Institute, commissioned Geogreen to undertake a study reviewing the current global portfolio of operational and announced CO<sub>2</sub> geological storage projects, in the context of key CCS deployment targets for 2020: 20 operational sites stipulated by the G8; and 100 operational sites as described in the 2009 IEA CCS Roadmap ‘Blue’ scenario (limiting atmospheric CO<sub>2</sub> concentrations to 450ppm). The Geogreen study included detailed modelling of the timescales and resources required for storage sites to achieve bankable status, whereby final investment decisions can be made in advance of site construction, commissioning and operations. Building on this analysis, the study showed that the current CCS project portfolio could allow the G8 target to be reached provided that adequate resources are made available for a large proportion of the proposed projects and that storage associated with CO₂-EOR can be included.
