D 4.1.1. Shortlist of potential CO₂ storage sites. WP 4.1 Technology screening and selection of CO 2 storage sites

This document is the deliverable from WP4.1, part of SP4 of the DYNAMIS project. The objective of SP4 is to generate the basis for recommending possible storage sites for CO₂ from a full-scale HYPOGEN demonstration plant. Based on an initial list of screening criteria, defining the information needed for a multi-criteria selection of possible storage sites, characteristics for a total of 80 storage sites have been collected. Data have been collected using existing GIS information from a number of other EU projects along with existing petroleum and public domain databases. The considered types of geological storage include depleted or mature oil and gas reservoirs, saline aquifers and abandoned gas storages.

Within DYNAMIS it has been agreed to perform the work of SP4 on an assumed plant size of 400 Mw being operational in 2012. Two fuels, gas and coal, are to be considered and are assumed to generate approx. 2.0 and 3.33 Mt CO₂ per year, respectively. With a plant lifetime of 30 years the corresponding total amounts of CO₂ is 60 and 100 Mt. Given the project constraints and the technical/geological constraints concerning geological storage of CO₂, a set of 10 final site selection criteria has been defined. Based on these a multi-criteria site selection has been performed, resulting in a shortlist of potential storage sites including 16 sites.

All the sites on the shortlist have been described in detail comprising geological setting, wells, trap and seal, storage potential etc. and in Appendix III are listed essential parameters for each site. Finally it is concluded that the selected sites all are well suited for storage of the amounts of CO₂ expected from a HYPOGEN demonstration plant.
