Summary: The equilibrium contact angles of H-2/brine on shale samples with different TOC at various pressures and temperatures were computed, showing a decrease in H-2 sealing capacity with increasing pressure, depth, and TOC values. CO2/brine equilibrium contact angles were generally higher than H-2/brine, suggesting potential use of CO2 as a cushion gas during UHS. However, the influence of increasing contact angles with pressure and TOC, and decreasing column height and capillary pressure with depth, on structural trapping capacities of shale caprocks might be limited due to the low densities of hydrogen.

Summary: With the potential of underground hydrogen storage (UHS) in depleted oil and gas reservoirs or deep saline aquifers, it is important to understand the changes to geological units caused by the interaction with injected hydrogen. This study reveals significant dissolution of calcite fossil fragments in claystone caprock proxies when treated with hydrogen and NaCl brine, a phenomenon observed for the first time in claystones. These findings highlight the need for hydrogen-specific studies of caprocks in areas proposed for UHS.

Summary: This study investigated the physisorption behavior of hydrogen on various earth minerals. The results showed that illite had the highest adsorption capacity, and high-surface-area materials like clays or kerogen exhibited better adsorption performance. These findings are important for evaluating the feasibility of underground hydrogen storage.

Summary: The study found that the presence of organic acids at specific pressures and concentrations can affect the wetting characteristics of geological formations, potentially leading to H-2 gas leakage. The influence of organic contamination in realistic geostorage conditions should be considered to avoid overpredicting structural trapping capacities and H-2 containment security.

Summary: The study explores the diffusion of hydrogen in caprock during geological storage and proposes a semi-analytical solution to predict hydrogen loss over time. The analysis shows that hydrogen loss is influenced by the interface between rock and reservoir, caprock porosity, and gas saturation, as well as diffusion coefficient and time. Taking into account the presence of hydrocarbon gas in the caprock is important for accurate estimation of hydrogen loss. The thermodynamic effects at high pressures result in a lower final loss of injected hydrogen.

Summary: Underground storage is a viable method for storing renewable energy as hydrogen. Determining the timing and amount of injected gas is crucial for the operation of such facilities. Modeling the injection of hydrogen into a deep aquifer helped assess the optimal flow rate and the benefits of extending the first filling period. Storage capacity increased with longer filling periods, and the recommended depth for hydrogen storage was found to be around 1200-1400 m.

Summary: Clean hydrogen is a promising option for reducing carbon dioxide emissions, but its use as an energy carrier at the scale required for meeting net-zero targets has not been achieved yet. This study investigates the flow behavior of hydrogen in the subsurface and compares it with nitrogen and methane. The results show that the existing knowledge of permeability in conventional gas reservoirs applies to hydrogen flow, but there are deviations in caprock.

Summary: This study evaluated the effect of adding different percentages and types of polymeric waste on the properties of soil-cement bricks. The results showed that adding 1.5% PET waste significantly improved the compressive strength and thermal conductivity of the bricks, while increasing to 3.0% led to a decrease in water absorption and compressive strength.

Summary: This article quantitatively evaluates the sealing capacity of the Permian mudstone caprock in the D5 block of the Litan sag, China, based on core observation, laboratory experiments, and well logging data. Important parameters affecting the sealing capacity are determined, such as mineral brittleness, permeability, breakthrough pressure, mechanical brittleness, thickness, and areal extent. The results of a mathematical evaluation model show that except for sample 2, all other samples have optimal sealing capacity. The field interference test shows that the optimal sealing capacity of the caprock meets the requirements of the construction of underground gas storage.

Summary: Rock-fluid interfacial tension (gamma(rock-fluid)) plays a crucial role in gas geo-storage, with pressure, temperature, organic acid, and silica nanofluid concentrations affecting its value. Understanding the variations of gamma(rock-gas) is essential for implementing a more sustainable energy supply chain in gas geo-storage. Insights on the order of gamma(rock-gas) for different gases provide guidance for optimizing gas storage and containment security.

Summary: The burning of fossil fuels has negative effects on global air quality, and alternatives like the hydrogen economy are needed. Hydrogen is an ideal replacement for fossil fuels due to its high energy density, abundance, and eco-friendly oxidation product. However, the development of safe, inexpensive, and compact storage materials for hydrogen remains a concern.
