Abstract: | This paper reports on the regional screening, selection and geological characterisation of a potential on-shore CO2 storage site (saline aquifer) in north-eastern Germany. The main objective of this study was to identify and investigate
a candidate storage site, capable to accommodate the total amount of approximately 400 million tons of CO2. Such a volume is produced by a modern, lignite-fired power plant within its operation lifetime of approximately 40 years.
Within north-eastern Germany, several saline aquifers of Triassic, Jurassic and Cretaceous age have been evaluated with respect
to their regional occurrence, storage potential and basic reservoir properties. Subsequent to a ranking, considering different
criteria, the anticlinal structure Schweinrich holding suitable saline aquifers of the uppermost Triassic and lowest Jurassic
has been selected from a number of identified candidate sites. According to results of the geological site characterisation,
including structural geological investigations and 3D reservoir modelling, the structure Schweinrich seems to be a suitable
site for industrial large scale CO2 storage. Further data acquisition (new wells and 3D seismics) and research (more detailed and comprehensive modelling) is
needed in order to prove the structural integrity of the storage site and assure long-term safety. |
