The EU Geocapacity Project- Saline aquifers storage capacity in Group South countries

Elsevier use only: Received date here; revised date here; accepted date here The EU Geocapacity Project aims to obtain an estimation of the potential capacity of CO2 storage in deep saline aquifers, depleted hydrocarbon fields and coal beds in Europe. Prior to this project, the availability of data to calculate the storage capacity differed very much in each country. Some of them have already provided estimations for CO2 storage capacities in the framework of previous projects (e.g. GESTCO (FP5) and CASTOR (FP6)), while other countries have not been evaluated at all. Therefore, an important part of the work performed in the frame of the GeoCapacity project has been to homogenise estimation methodologies and reliability of data. Emphasis has been placed on the study of saline aquifers, as this type of geological formation, was until now, the less studied and most poorly understood compared to the depleted oil and gas fields. The work activities were organized in geographical groups to make them easier to manage
