The DELPHI Expert Process of the German Umbrella Project AUGE - Status of CO2 Storage in Germany and Recommendations to the Review Process of the German CO2 Storage Legislation

To scientifically underpin the German national “Carbon Dioxide Storage Law” (KSpG) and derive recommendations for its review and implementation, a Delphi expert process was initiated within the national German umbrella project AUGE. In two Delphi rounds experts from science, industry and regulatory bodies were asked for their assessment of CO2 storage in general and the KSpG in particular. Overall, CO2 storage is seen essential for reaching a 2°C target and experts agree that knowledge and technology allow implementing a demo-scale project. However, experts also agree that the current KSpG version prevents implementation of CCS in Germany and requires revision.
