Abstract [en]

To make large-scale CO2 storage economic, many groups have proposed using CO2 in EOR projects to create value for CO2 storage. However, CO2 EOR projects generally require a large and variable supply of CO2 and consequently may require temporary storage of CO2 in geological formations. In order to store CO2 at offshore sites as a source for CO2 EOR projects, the CO2 needs to be extracted from a storage site to a certain extent. Alternatively, CO2 EOR projects may be developed alongside saline aquifer CO2 storage with only some of the CO2 being used for EOR. The idea of temporary storage of CO2 may therefore be a key part of the solution for today?s climate challenge regarding CO2 emissions. Seasonal storage of dry methane gas is a well-established technique, and based on this project, it can also work for CO2. This project examines the effectiveness of geological storage and re-use of CO2 compared to seasonal dry gas storage. The controls on injection and production of CO2 from an ideal storage geological site is estimated.
