This talk by Prince Ochonma, Research Specialist from Cornell University's Department of Civil and Environmental Engineering, explores an innovative approach to sustainable resource management through subsurface CO2 mineralization. Discover how earth-abundant, iron-rich minerals can be leveraged for simultaneous recovery of energy-relevant metals and generation of geologic hydrogen through reactive carbon dioxide mineralization. Learn about the geochemical mechanisms driving these transformations, with particular focus on how mineral heterogeneity, fluid chemistry, and reaction pathways can optimize co-production outcomes. The presentation demonstrates how coupling metal extraction with in-situ hydrogen evolution and permanent carbon storage creates a novel pathway for sustainable resource recovery while contributing to decarbonization efforts. The one-hour talk is presented by the Bureau of Economic Geology.
