Assessing the European potential for geological storage of CO2: The GESTCO project

Abstract

The inventory of major point sources of CO2 and the geological storage potential mapped in the GESTCO project indicate that the eight European countries could make a significant impact on their national CO2 emissions by capturing, the emissions from a relatively small number of the largest point sources and storing them underground. In Denmark, mapping of geological structures suitable for underground storage of CO2 suggests that enough storage volume is present within the subsurface to store several hundred years of total CO2 emissions from Danish industry and power production. Detailed site surveys and risk analysis, including long term monitoring, are needed to validate these storage capacities and should be the focus of future studies.
