Oregon State researchers, Anna Herring and Linnea Andersson, looked at supercritical CO2 and saltwater flow processes in sandstone rock cores at GSECARS, 13 BMD. This research helps to understand and design geologic CO2 sequestration projects. Geologic CO2 sequestration is a climate change mitigation strategy; the idea is that we can limit carbon emissions to the atmosphere by capturing and isolating carbon dioxide (CO2) from the smoke stacks of fossil fuel power plants, and pump the CO2 underground instead of letting it out into the atmosphere. This would allow us to continue to use fossil fuels for energy (for example, coal) without contributing to climate change.
