Laboratory-scale experimental equipment for the study of geochemical processes (gas dissolved in water and rock)
Entity:
Experimental equipment to perform (1) continuous flow (columns and rock cores) and (2) batch type (autoclave; crushed material) experiments to study the interaction of dissolved hydrogen in groundwater with storage rock and/or cap rock. Pressure and temperature conditions are from 0.1 MPa to 10-15 MPa and 10-90 °C, respectively.
Challenges met
- Investigation (quantification) of geochemical processes in the interaction of dissolved hydrogen in groundwater with storage rock and/or cap rock.
- Obtaining kinetic data (e.g. dissolution reaction rates of the minerals that make up the rocks) that are included in the reactive transport models.
Scope of application
- Research centres, industry.
