Coupled CO2 Mineralization and Hydrogen Generation in Mafic–Ultramafic Rocks: Laboratory Measurements, Numerical Modeling and Field studies

Session ID#: 282178

Session Description:
Mafic and ultramafic rocks show significant potentials in permanent CO2 storage via mineralization, and geological hydrogen (H2) generation via water–rock redox reactions. The two processes are linked through fluid flow, mineral dissolution, secondary-mineral precipitation, and pore-space evolution. This session integrates laboratory, modeling, and field studies to advance the fundamental understanding of coupled CO2 mineralization and H2 generation across scales. We invite contributions addressing:

  • Mineralogical and geochemical control on CO2 mineralization and natural H2 generation in mafic–ultramafic systems;
  • Mechanistic links and feedbacks between CO2 mineralization and H2 generation water-rock reactions;
  • Dissolution–precipitation reactions, interfacial processes, and pore structure evolution during CO2 mineralization and H2 generation;
  • Chemo-mechanical coupling and reaction-driven fracturing during CO2 mineralization and H2 generation;
  • Technology, infrastructure, and policy challenges toward commercial deployment. Cross-disciplinary contributions linking laboratory, modeling, and field studies are particularly encouraged.
