Why Geochemical Modelling CO2 Storage?

Marianne Nuzzo

Seep biogeochemistry & organic geochemistry

The geological storage of CO2 is a promising means to help reduce the emissions of greenhouse gases into the atmosphere during the energy transition stages (e.g., Raza et al., 2022). Carbon Capture and Storage (CCS) is one of the essential technologies required to achieve global temperature rise limitations (IPCC, 2022) by contributing to the mitigation of carbon emissions from energy and industrial plants during the transition and is furthermore expected to support direct CO2 removal from the atmosphere on a longer timescale (Snaebjörnsdóttir et al., 2020).

Mechanisms and advantages of CO2 storage in basalt reservoirs

Storage of CO2 in geological formations depends on a combination of physical and chemical mechanisms such as physical trapping below caprocks or trapping by dissolution in groundwater. The most effective storage mechanism is the permanent mineralisation of CO2 by conversion into carbonate minerals (Benson et al. , 2005).
