7. ECONOMIC ANALYSIS

Costs estimates on CO2 storage involve a high degree of uncertainty, given the significant variations in technical characteristics, scale and applications between projects. There is also uncertainty over how costs will develop with time. Site selection and the economics of storage will drive the commerciality of large-scale integrated CCS projects and without appropriate storage options, CCS may not be a cost-effective CO2 mitigation option.

 

A small number of studies, articles and reports focus exclusively on the COst of CO2 storage for CCS. There is a high degree of uncertainty in estimating the COsts of CO2 storage, given the significant variations between projects' technical characteristics, scale and applications. There is also uncertainty over how COsts will develop with time (ipcc, 2005; IEA, 2009; GCI, 2010). Still, the storage site selection will drive the COmmerciality of large-scale integrated CCS projects and without appropriate storage options CCS may not be a COst-effective CO2 mitigation option (GCI, 2011).
