Th e challenge of climate change demands reduction in global CO 2 emissions. In order to fi ght global warming many coun- tries are looking at technological solutions to keep the release of CO 2 into the atmosphere under control. One of the most promising techniques is carbon dioxide capture and storage (CCS), also known as CO 2 geological storage. CCS can re- duce the world’s total CO 2 release by about one quarter by 2050 (IEA 2008, 2013; Metz et al. 2005). CCS usually in- volves a series of steps: (1) separation of the CO 2 from the gases produced by large power plants or other point sources, (2) compression of the CO 2 into supercritical fl uid, (3) trans- portation to a storage location and (4) injecting it into deep underground geological formations. CO 2 StoP is an acronym for the CO 2 Storage Potential in Europe project. Th e CO 2 StoP project which started in Janu- ary 2012 and ended in October 2014 included data from 27 countries (Fig. 1). Th e data necessary to assess potential loca- tions of CO 2 storage resources are found in a database set up in the project. A data analysis system was developed to analyse the com- plex data in the database, as well as a geographical informa- tion system (GIS) that can display the location of potential geological storage formations, individual units of assessment within the formations and any further subdivisions (daugh- ter units, such as hydrocarbon reservoirs or potential struc- tural traps in saline aquifers). Finally, formulae have been developed to calculate the storage resources. Th e database is housed at the Joint Research Centre, the European Commis- sion in Petten, the Netherlands. Background and methods CO 2 storage resource assessment A resource can be defi ned as anything potentially available and useful to man. Th e pore space in deeply buried reservoir rocks that can trap CO 2 is a resource that can be used for CO 2 storage. It is of utmost importance to be aware that the mere presence of a resource does not indicate that any part of it can be economically exploited, now or in the future
