“…As early as 1992, Handa explored the conditions for methane to form hydrates on silica gel, which provided an idea of wet storage of methane with porous materials. The study found that mesoporous materials can not only increase the gas–liquid contact area during the formation of hydrates but also overcome some of the shortcomings of pure water hydrate storage methods through their catalytic effects. − …”

SBA-15 mesoporous molecular sieves were used as the adsorption medium to capture carbon dioxide by the gas hydrate method. First, it is confirmed that the synthesized SBA-15 material has a uniform pore size with the 77 K nitrogen adsorption− desorption isotherms and transmission electron microscopy analyses. Second, the effects of the capture of carbon dioxide on the SBA-15 material by adding different amounts of water were investigated. Each adsorption isotherm of the SBA-15 material with different presorbed water has a jump point, and the adsorption capacity of CO 2 increased with the increase of the water−sample ratio (R w , the mass ratio of the preadsorbed water and the dry SBA-15 material). At 2.5 MPa, the adsorption capacity of R w = 2.0 is 20.14 mmol/g and that of the dry material is 3.86 mmol/g. The optimal water−sample ratio was determined to be 2.0. The formation of carbon dioxide hydrate of the jump point on the wet SBA-15 is verified by the enthalpy of capturing carbon dioxide. Finally, the effects on carbon dioxide hydrate formation at the wet SBA-15 material with different surfactants [SDS, sodium dodecyl benzene sulfonate (SDBS), and polysorbate 80 (Tween 80)] were investigated. The results show that the promoting effects of different types of promoters increase first and then decrease with increasing concentration. The optimal concentrations of SDS, SDBS, and Tween 80 are 1000, 1500, and 1000 mg/L, respectively. The wet SBA-15 with 1500 mg/L SDBS has the best promotion effect among the three surface surfactants.

“…Furthermore, nanoparticles function as modifiers. NPs such as metal–organic frameworks (MOFs), zeolites, or functionalized carbon nanotubes are notable, altering CO 2 hydrates’ properties and affecting dissociation kinetics, storage capacity, or other crucial characteristics. ,, Numerous experimental and numerical simulation studies have revealed that NPs, particularly silica NPs, graphite NPs, and metal NPs, have a positive effect on the promotion of CO 2 hydrate formation and stability , The presence of NPs has been found to reduce the induction time and increase CO 2 gas consumption during the CO 2 hydrate formation process. ,, According to the study by Cao, NPs were observed to enhance the stability of CO 2 hydrate structures. NPs contributed to the evolution of structural stability of CO 2 hydrate–sand nanoparticle systems, as evidenced by the evolutions of potential energy and the number of hydrogen bonds.…”

Exploring various strategies for CO 2 hydrate storage in subseafloor saline sediments reveals a promising yet challenging path toward mitigating anthropogenic CO 2 emissions and advancing clean energy development. Research has revealed the efficacy of sediment-specific modifications, including the use of inorganic emulsifiers, L-leucine (an amino acid), and nanoparticle coatings, in enhancing CO 2 hydrate formation stability and storage capacity. These modifications aid in overcoming the challenges posed by the harsh environmental conditions of salinity and sediment heterogeneity, providing increased stability, enhanced CO 2 adsorption efficiency, and reduced induction time. Furthermore, advancements in nanomaterials have introduced nanostructured encapsulation systems capable of confining and stabilizing CO 2 within a solid matrix under fluctuating pressure, temperature, and salinity conditions. Incorporating nanoparticles into polymers and surfactants yields a nanofluid that exhibits increased stability, improved wettability, interfacial tension (IFT) reduction, and elevated CO 2 hydrate storage efficiency, with the synergistic effects of these components playing a critical role. Moreover, innovative thermal and pressure manipulation strategies, alongside the integration of kinetic promoters, have shown significant potential in optimizing CO 2 hydrate formation kinetics and enhancing longterm stability. These strategies involve novel electrical heating systems, pressure management techniques, and chemical additives that collectively contribute to increased hydrate formation rates and gas storage capacities. Despite these promising developments, the field faces several challenges, including optimizing encapsulation materials to match geological characteristics, the long-term stability of CO 2 hydrates under extreme conditions, and scaling laboratory experiments to field applications. Addressing these issues necessitates a multifaceted approach, incorporating empirical data and theoretical insights to design, screen, and formulate effective CO 2 hydrate storage solutions in subseafloor saline sediments.
