The management of anthropogenic CO2 will be one of the main challenges of this century given the dramatic impact of greenhouse gases on our living environment. It is now critical, not only to develop technologies allowing the reduction of CO2 emissions, but also to provide solutions to capture and use/store industrial CO2 emissions. Among the various Carbon Capture Utilization and Storage (CCUS) strategies, CO2 geological storage in deep saline aquifers represents a viable mediation solution for reducing the anthropogenic CO2 emissions. So far, little is known about both the CO2 storage impact on the underground geochemistry and on the microbial diversity inhabiting deep aquifers. Consequently, this kind of storage required adequate scientific knowledge and tools at the pore scale to evaluate injection scenarios or to estimate reservoir capacity. In this context, high pressure / high temperature microfluidic reactors (micromodel or geological labs on chip – GloCs) turn out to be excellent tools to investigate the different mechanisms associated with CO2 geological storage in deep saline aquifers.
