Actualization of the hydrogen (H2) economy and decarbonization goals can be achieved with feasible large-scale H2 geo-storage. Geological formations are heterogeneous, their wetting characteristics play a crucial role in presence H2, which controls pore-scale distribution fluids sealing capacities caprocks. Organic acids readily available geo-storage minute quantities, but they highly tend to increase hydrophobicity storage formations. However, there is paucity data on effects organic acid concentrations types H2-wettability caprock-representative minerals attendant structural trapping capacities.Geological contain concentrations, alkyl chain length ranging from C4 C26. To fully understand natural geological picture, we aged mica mineral surfaces as representative caprock varying molecules (with numbers carbon atoms, lignoceric C24, lauric C12, hexanoic C6) for 7 days. comprehend wettability mica/H2/brine system, employed contact-angle procedure similar that environments (25, 15, 0.1 MPa 323 K).At highest investigated pressure (25 MPa) concentration (10-2 mol/L), surface became completely wet advancing (θa= 106.2°) receding (θr=97.3°) contact angles. The order increasing θa θr contaminations follows: > acid. results suggest gas leakage through possible at higher physio-thermal conditions. influence contamination inherent realistic conditions should considered avoid overprediction containment security.

Replacement of fossil fuels with clean hydrogen has been recognized as the most feasible approach implementing CO2-free economy globally. However, large-scale storage is a critical component value chain because lightest molecule and moderately low volumetric energy content. To achieve successful buoyant at subsurface convenient withdrawal during period demand, integrity underground rock overlying seal (caprock) must be assured. Presently, there paucity information on wettability shale interfacial properties H2/brine system. In this research, contact angles shale/H2/brine system hydrogen/brine tension (IFT) were measured using Krüss drop shape analyzer (DSA 100) 50 °C varying pressure (14.7–1000 psi). A modified form sessile was used for measurement, whereas H2-brine IFT through pendant method. values decreased slightly increasing pressure, ranging between 63.68° 14.7 psia 51.29° 1000 psia. The Eagle-ford moderate total organic carbon (TOC) 3.83% attained fully hydrogen-wet (contact angle 99.9°) intermediate-wet condition 89.7°) psi 200 respectively. Likewise, Wolf-camp TOC (0.30%) weakly water-wet conditions, 58.8° 62.9°, maximum height that can securely trapped by approximately 325 meters merely 100 shale. Results study will aid in assessment capacity organic-rich (adsorption trapping), well evaluation sealing potentials storage.

Influence of organics and gas mixing on hydrogen/brine and methane/brine wettability using Jordanian oil shale rocks: Implications for hydrogen geological storage

Journal of Energy Storage, Journal Year: 2023, Volume and Issue: 62, P. 106865 - 106865

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 objective due the low volumetric energy density H2. In storage, cushion gases, such methane (CH4), are required maintain safe operational formation pressure during withdrawal or injection wetting characteristics geological formations in presence H2, gas, and resultant gas mixture mixing zone between them essential for determining storage capacities. Therefore, present work measured contact angles four Jordanian oil shale rocks CH4, H2-CH4/brine systems their interfacial tension (IFT) (geo-storage) conditions (pressures 0.1 1600 psi temperature 323 K) evaluate residual structural trapping potential efficiency CH4 gas. Various analytical methods were employed comprehend bulk mineralogy, elemental composition, topographic characterization, functional groups, surface properties rocks. total organic (TOC) effect on wettability was demonstrated compared previous studies. samples high ultrahigh TOC 13 % 18 exhibited brine advancing/receding angles. rock became hydrophobic highest experimental (1600 K). rock/CH4/brine higher than rock/H2/brine angles, remained those pure gases. Moreover, IFT displayed inverse trend, where H2/brine CH4/brine IFT. results suggest that geo-storage tested organic-rich source could favorable when is used consistent studies using synthetically acid-aged samples. For first time, from more realistic situation influence missing material H2/brine/rock geo-storage.

Hydrogen (H2) storage in geological formations offers a potential large-scale solution suitable for an industrial-scale hydrogen economy. However, the presence of organic residuals can significantly influence H2 efficiency, as well cushion gas performance, such CO2 and CH4, injected to maintain healthy reservoir pressure. Thus, efficiency selectivity were thoroughly investigated this work based on H2, CO2, CH4 adsorption measurements using, first time, actual organic-rich carbonate-rich Jordanian source rock samples (TOC = 13 % 18 %), measured at 60 °C temperature wide range pressure (0.1 – 10.0 MPa). Initially, characterized using various analytical methods. Results demonstrated that capacities reached up 0.47 mol/kg 9.0 MPa. The was four times higher than H2. An increase TOC decreased compared CH4. Additionally, preferential behavior attributed mainly calcite content carboxyl sulfonyl groups. This study provides fundamental data understanding issues formation thus aids industrial implementation supply chain.
