Gas Hydrate Formation, Stability and Carbon Dioxide Sequestration
This community investigates the molecular physics and chemistry of gas hydrates—cage-like ice structures that trap gas molecules—and applies this knowledge to store carbon dioxide and manage natural gas resources.
The research focuses heavily on the formation kinetics, phase equilibria, and dissociation mechanisms of methane and carbon dioxide hydrates. A significant portion of the work utilizes molecular dynamics simulations to model the behavior of water and gas molecules at the interface, particularly in the presence of salts like sodium chloride. The community also explores the use of promoters such as amino acids and surfactants to enhance hydrate stability and storage capacity. Specific applications include carbon capture and storage in deep-ocean sediments and underground reservoirs, as well as the inhibition of unwanted hydrate formation in pipelines. Spectroscopic techniques, including Raman and sum frequency generation, are frequently employed to probe the hydrogen-bond networks and structural changes within these aqueous systems.
The community is most prominent in research tracked for Hydrogen, where it constitutes 0.5% of all hydrogen-related papers, and for Chlorine, accounting for 0.6% of chlorine research. It also represents a small but distinct share of Carbon and Sodium research.
There are 13,665 papers in this community, with the highest publication volumes in The Journal of Chemical Physics, The Journal of Physical Chemistry B, and The Journal of Physical Chemistry.
Recent work continues to focus on optimizing carbon dioxide sequestration via hydrate formation in various geological settings, including deep-ocean sediments and non-permafrost sites. Newer studies also examine the use of machine learning to predict hydrate mechanical properties and the role of water-soluble polymers in inhibiting methane hydrate formation.
