Developments of CO2 Geological Storage in Europe and the Role of CO2GeoNet

International audience; Since the very first European research project initiated in 1993, much progress has been made in Europe on the development ofCO2 geological storage as a key tool for combating climate change. A review of the main achievements and remaining obstaclesin Europe is proposed, with a glance at what is going on at global level. Scientific, technical, economic, regulatory and policyaspects are considered. The increasing role of the growing CO2GeoNet Association, a reference pan-European scientific body onCO2 geological storage, is emphasized, with actions both on the EU and global scene for enabling efficient and safe storage.
