CCS site characterisation criteria
1st July 2009
The IEA Greenhouse Gas R&D Programme (IEA GHG) has recently commissioned the Alberta Research Council in Canada to conduct a review of storage site selection criteria and site characterisation methods in order to produce a synthesis report. Among the various elements of the CO2 capture and storage (CCS) chain, the stage of storage site selection and characterisation is of critical importance because any storage site must demonstrate that it satisfies three fundamental requirements:
- capacity to store the intended volume of CO2 over the lifetime of the operation,
- injectivity, to accept/take CO2 at the rate that it is supplied from the emitter(s),
- containment, to ensure that CO2 will not migrate and/or leak out of the storage unit (safety and security of storage).
This report reviews the literature on the subject on site selection and characterisation since the publication of the IPCC Special Report on CCS, and provides a synthesis and classification of criteria.
