The interfacial tension (IFT) between the reservoir fluids and the solubilities of the injected
hydrogen and cushion gas in the underground brine plays a critical role in the security and …

Carbon Dioxide (CO 2) emissions from fossil fuel consumption have caused global warming
and remain challenging problems for mitigation. Underground Hydrogen Storage (UHS) …

Underground hydrogen storage (UHS) offers a promising approach for the storage of
significant volumes of hydrogen gas (H 2) within deep geological formations, which can later …

The growing interest in large-scale underground hydrogen (H2) storage (UHS) emphasizes
the need for a comprehensive understanding of the fundamental characteristics of …

In this study, the wettability of a kerogen surface, a key component of shale reservoirs, is
investigated by using molecular dynamics simulations. Specifically, we examined the impact …

The understanding of interfacial phenomena between H2 and geofluids is of great
importance for underground H2 storage, but requires further study. We report the first …

A multicomponent wetting model of coal–water–methane–hot flue gas was hereby
constructed to investigate the influence of complex components of hot flue gas on coal …

Underground H 2 storage (UHS), ie, injecting H 2 into subsurface geological formation and
its withdrawal when needed, is identified as a promising solution for large-scale and long …

The effects of impurity gases on interfacial characteristics of hydrogen-water-oil three-phase
systems are critical to underground H 2 storage in depleted oil fields but have not been …

Recent research has primarily focused on 2-phase systems for hydrogen storage in porous
media. However, the impact of cushion gases mixed with hydrocarbon fluids, such as n …
