Geologic carbon capture and storage (CCS) involves the injection of CO2 in a gaseous to supercritical state into subsurface formations, including oil beds, deep coal seams, and deep saline aquifers. Microbiological life is inherent in all such subsurface environments proposed for CCS. However, the impact of CCS on existing microbiological life and the impact of such life on the operation of CCS still received limited consideration, although a number of biogeochemical processes may also enhance or inhibit the operation of CCS. Research of native bacterial communities and their response to CO2 injection and research focused on assessing the role of microbial components, their exometabolites and dissolved organic substances in mineral dissolution/precipitation reactions under subsurface conditions in various geological settings are welcome. Research considering the physico-chemical and microbiological aspects of CO2 sequestration (biomineralization) in the form of carbonate minerals) in both subsurface but also model surface environments suitable for the enhancement of CCS is also encouraged. This session aims to bring together researchers in the field of CCS who are considering such questions through laboratory, field and modelling based research.
