Title:
High-Resolution SEM & Maps Min Automated Mineralogy for Emerging Geo-Energy Systems: From Natural Hydrogen to Geothermal Reservoirs and Carbon Mineralization

Abstract:
The rapid growth of emerging geo-energy sectors, natural hydrogen, deep geothermal systems, and CO₂ mineral storage, requires analytical tools capable of resolving mineralogical and geochemical processes across scales with high throughput and quantitative reliability. The integration of Scanning Electron Microscopy (SEM) with Maps Min automated mineralogy provides fast, reproducible, and high-resolution mineral and elemental mapping. Applied to natural hydrogen generation, crystalline geothermal reservoirs, and CO₂ mineralization in basalts, this approach reveals the multi-scale distribution of reactive minerals, the impact of hydrothermal alteration on reservoir properties, and the controls on carbonate precipitation. These case studies demonstrate that automated mineralogy is a key technology for linking microstructures, rock reactivity, and reservoir performance, thereby accelerating the development of next-generation geo-energy solutions.
