Division/Committee: [GEOC] Division of Geochemistry

Carbon mineralization in reactive reservoirs (i.e. basalt, peridotite) is being explored for permanently sequestering CO2 through mineralization. Commercial scale subsurface sequestration requires a Class VI well permit. Acquisitions of a Class VI permit requires reservoirs benchmarked and parameterized by field- and laboratory-derived data, enabling accurate predictions of the fate and transport of the injected CO2. This data includes temperature- and pressure-dependent kinetics of mineral dissolution, secondary mineral crystallization, and secondary mineral identity. Subsurface injection and mineralization of CO2 is additionally being explored as an aid in critical mineral release and recovery. This session is motivated by the need to assess the state of science in understanding the complex and key processes occurring at mineral-water interfaces within the applied context of carbon mineralization and critical mineral recovery. Contributions are invited that highlight the fundamental and applied geochemistry at the mineral-water interface as it relates to mineral dissolution, precipitation, carbon mineralization, and critical mineral recovery, as well as emerging experimental techniques to understand these processes. We encourage submissions that utilize bench scale experiments, molecular simulations, and reactive transport models.
