Guest enclathration and structural transition in CO2+ N2+ methylcyclopentane hydrates and their significance for CO2 capture and sequestration

Surface morphology effects on clathrate hydrate wettability

“…In contrast to the results shown for water droplets on C5 hydrates (see Fig. 4D), the local/apparent contact angles on rough C1-C2 hydrates immersed in C12 increase significantly (from 30°to 45°) when the droplet volume increases from 28 to 42 nm 3 . The pinning effects appear to be more pronounced for small droplets on rough C1-C2 hydrates in C12 compared to the ones on rough C5 hydrates (see Figure S3).…”

“…Gas hydrates naturally form under certain conditions of pressure and temperature because of a balance between water-water hydrogen bonds and host-guest (i.e., water-methane) dispersive interactions [1]. Over the last decade, gas hydrates have attracted significant focus because of their possible applications in various sustainable and environmental technologies [2][3][4][5][6][7][8][9]. Natural gas hydrates could also provide an alternative energy source; notwithstanding their environmental effects should be understood, prevented and mitigated when necessary [8,10].…”

Molecular mechanisms by which tetrahydrofuran affects CO2 hydrate Growth: Implications for carbon storage

“…Currently, the growth of interest in the hydrate research field inclines towards the expansion of gas hydrate applications in water-energyenvironment nexus including water desalination [9,10], gas separations [11,12], intermittent natural gas and hydrogen storage [13][14][15][16][17], refrigeration and transport [18,19]. Further, attention is today focused on approaches to mitigate global warming through long-term CO 2 capture and sequestration, which could be achieved via the formation of CO 2 hydrates [20][21][22][23][24].…”

Correlating Antiagglomerant Performance with Gas Hydrate Cohesion

“…Gas hydrates are relevant for a variety of sectors, including energy, environment, and sustainability. With the goal of increasing the sustainability of our society, recent research advances have extended the utilization of gas hydrates in various applications, including but not limited to hydrogen and energy storage, − CO 2 capture and sequestration, − water desalination, , gas separation, , refrigeration and transport, etc. Naturally occurring gas hydrates attract considerable attention for their potential role in providing an alternative energy source, although their environmental impacts should be mitigated. , On the other hand, safety in the energy sector is frequently associated with the prevention of hydrate agglomeration in oil/gas pipelines .…”
