Summary: Hydrogen is considered a clean fuel for mitigating climate change by reducing greenhouse gas emissions, but large-scale storage of hydrogen is a challenge due to its compressibility, volatility, and flammability. This review focuses on the wettability of hydrogen in geological formations as a potential storage solution. It discusses the influence of parameters such as salinity, temperature, pressure, surface roughness, and formation type on wettability and storage capacity. The review also discusses the effect of organic material and presents influential parameters affecting storage safety. Overall, this review provides valuable insights for understanding hydrogen storage challenges and identifying storage solutions.

Summary: Rock wettability is a key factor in the storage of hydrogen, affecting its capacity and safety. The study found that under realistic storage conditions, the surface of bituminous coal exhibited weak water-wettability. The pressure of hydrogen increased the contact angles of brine on the coal surface at 25 degrees C but had no impact at higher temperatures. A thermodynamic model was proposed to describe the observed behavior, supporting the development of large-scale geostorage technologies for hydrogen.

Summary: Contact angle is a measurement of the wettability of solid surfaces, and the wettability of rock/oil/brine systems can be modified by using solvents for surface cleaning. This study found that different solvents used for cleaning the rock surface can have different effects on the wettability of the rock/oil/brine system.

Summary: This study aims to improve the performance of floating solar still by altering the wettability and contact angle hysteresis of the cover surface. The results show that while wettability does not significantly affect transmissivity and absorber temperature, low contact angle hysteresis in the anti-fog film increases water collection. Additionally, the distilled water has a lower microbial content, making it suitable for domestic use.

Summary: A profound understanding of the properties of unmodified and saturated fatty acid-modified calcite surfaces is essential for elucidating their resistance and stability in the presence of water droplets. Additional insights can be obtained by also studying the effects of carboxylic acid-saturated aqueous solutions. Our findings suggest that during droplet reverse dispensing and droplet evaporation, pinning of the three-phase contact line leads to the transport of dissolved fatty carboxylic acid and possibly calcium bicarbonate molecules to the contact line boundary.

Summary: The aim of this study was to quantify the surface wettability of metallic surfaces covered with sprayed paints. The results showed that the treated surfaces exhibited hydrophobic water/solid interactions and the surface roughness and heterogeneity affected the wettability. The findings are important for surface-mediated process studies such as lubrication, liquid coating, and thermoflow.

Summary: Droplet and bubble wetting behaviors have significant differences, and surface roughness affects the wetting behaviors. The study reveals a critical Young contact angle for bubble wetting, above which apparent contact angle and contact angle hysteresis abruptly change. Increased roughness reduces bubble apparent contact angle and contact angle hysteresis.

Summary: This paper reports experimental measurements of advancing and receding contact angles for H-2/water system in microfluidic chip with different channel widths. Results show that contact angles decrease with increasing channel widths and N-2/water and CO2/water systems exhibit similar characteristics as H-2/water system.

Summary: This study provides an overview of research on wettability and interfacial tension in the shale-CO2-brine system, as well as the investigation of representative caprock minerals. It highlights the potential adverse effects of long-term CO2 interaction with clay-rich shale on wettability and interfacial tension, and the possibility of altering shale characteristics through the use of nanoparticles and surfactants. The study also identifies knowledge gaps in the understanding of acidic conditions caused by CO2 dissolution and the presence of free water in CO2-shale interactions, and recommends further research in these areas.

Summary: The impact of different plasma treatments on medical grade polyvinylchloride in terms of wettability and chemical composition was studied. Corona plasma treatment significantly enhanced its hydrophilic properties, while oxidation was hardly correlated with hydrophobic recovery, mainly attributable to the bulk mobility of polymer chains.

Summary: This study investigates the contact angle variations of fluids at different stages of flow using direct pore-scale measurements. The results show that the contact angle patterns depend strongly on the type of non-wetting fluid, and the interplay between pore geometry and the forces deforming the fluid interface has a significant impact on the contact angle.

Summary: Reducing the loss of injected hydraulic fracturing fluids into shale along fracture-matrix boundaries is difficult with alterations in interfacial properties and capillary forces in deep gas reservoirs, as the injection pressure at the fracture-matrix boundary plays a crucial role. Instead, practical options for reducing imbibition losses of water-based fluids in deep reservoirs may involve decreases in wellbore shut-in pressures and shut-in times.

Summary: Quantifying flow and transport from hillslopes is crucial for understanding water quantity and quality in rivers, but the limited subsurface measurements make it not clear enough. Optimizing subsurface flux predictions and pore water chemistry profiles over multiple years can predict the time-dependent rates of solute exports from hillslopes.

Summary: The imbibition of water into fractured unconventional reservoirs leads to significant water loss and restricts gas flow. Minimizing water usage during fracturing process is important for water conservation and gas production. This study proposes new scaling relations and a method for quantifying uncertainties in water imbibition. The approach was validated using experiments and provides a methodology for optimizing interventions in deep unconventional shale gas reservoirs to minimize water loss.
