Bio-Grouting Applications in Long-Term Caprock Sealing for CO2 Sequestration

Sang, Guijie (Principal Investigator) Davis, Geo (Principal Investigator) Terziev, Momchil (Principal Investigator)

Geological CO2 storage is a promising strategy to mitigate the emission of greenhouse gases generated from traditional power stations and energy-intensive industries. Caprocks are layers of low-permeability and ultra-fine porosity, consisting of massive consolidated clay-rich sediments (shale) and evaporites such as anhydrite. When positioned above a potential storage reservoir rock (e.g. a high porosity sandstone) a caprock creates a capillary barrier that ensures the retention of CO2 in the reservoir. However, caprock can contain fractures, either naturally existing or artificially induced due to injection, that may provide preferential paths for CO2 escaping. Seeking an efficient technique to seal and strengthen caprock fractures is crucial. Our vision is to harness our multidisciplinary expertise to contribute to the UK’s 2050 Net Zero target by providing evidence for developing and delivering an effective bio-mediated grouting strategy for caprock sealing, thus ensuring long-term safe CO2 sequestration. The proposed project also aligns well with the upcoming COP26 remit to tackle global climate change by reducing greenhouse gas emissions.
