The success of geological H2 storage relies significantly on rock–H2–brine interactions and wettability. Experimentally assessing the H2 wettability of storage/caprocks as a function of thermos-physical conditions is arduous because of high H2 reactivity and embrittlement damages. Data-driven machine learning (ML) modeling predictions of rock–H2–brine wettability are less strenuous and more precise. They can be conducted at geo-storage conditions that are impossible or hazardous to attain in the laboratory. Thus, ML models were utilized in this research to accurately model the wettability behavior of a ternary system consisting of H2, rock minerals (quartz and mica), and brine at different operating geological …

The substitution of fossil fuel with clean hydrogen (H2) has been identified as a promising route to achieve net zero carbon emissions by this century. However, enough H2 must be stored underground at an industrial scale to achieve this objective due to the low volumetric energy density of H2. In underground H2 storage, cushion gases, such as methane (CH4), are required to maintain a safe operational formation pressure during the withdrawal or injection of H2. The wetting characteristics of geological formations in the presence of H2, cushion gas, …

Hydrogen-Wettability Alteration Of Indiana Limestone In The Presence Of Organic Acids And Nanofluid, Mirhasan Hosseini, Rossen Sedev, Mujahid Ali, Muhammad Ali, Jalal Fahimpour, Alireza Keshavarz, Sefan Iglauer
Research outputs 2022 to 2026
This study focuses on the wettability alteration (changing from a hydrophobic state to a hydrophilic state) of Indiana limestone for hydrogen (H2) geological storage. We examine the effect of hexanoic acid C6, lauric acid C12, and stearic acid C18, on the wettability of Indiana limestone at ambient (298 K and 0.1 MPa) and reservoir (323 K and 8.27 MPa) conditions. The effects of silica nanofluids (silica with deionized water) at various concentrations (0.1 wt%, 0.25 wt%, and 0.5 wt%) on the wettability reversal of stearic-aged samples were tested at ambient and reservoir …
