CO2-USG-RISK
Assessment of the Long-Term Risk and Sustainability of Underground Storage of CO2 in Germany Current Practices, Future R&D Needs and Development of Methodologies
The general objective of the project is the development of a common performance assessment methodology for geological CO2 storage options that shall be applicable for typical sites located in Germany. This will include the adaptation of the Features-Events-Processes (FEP) procedure that is used in assessing the risks associated with the underground disposal of radioactive waste. This approach allows to identify and rank the critical performance parameters for underground CO2 storage. For each of the three geological storage options in Germany (depleted gas field, saline aquifer, unminable coalbed) a comprehensive set of scenarios, including the normal evolution and the disturbed evolutions, will be derived on the basis of the relevant FEPs and the most important loss of CO2 containment modes will be identified. Subsequently, for one storage option performance assessment calculations will be carried out for a hypothetical site that resembles a typical geological situation, in order to demonstrate the applicability of the approach. On the basis of this, unresolved scientific and technical questions will be identified and, as far as possible, feasible solutions will be proposed or additional RTD work will be recommended.
