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.

“…The results showed that the rate of hydrate formation was affected by the convective diffusion of gas, and the temperature contributes more. Li et al [23] investigated the kinetic characteristics of hydrate formation under CO 2 + N 2 gas mixture seepage conditions. The results showed that CO 2 + N 2 hydrate formed nucleation at one location and then expanded outward in the freshwater environment, and the temperature increased sequentially during the process.…”

Carbon sequestration through CO2 injection into a formation is an effective strategy for reducing greenhouse gas emissions. In this study, a one-dimensional long reactor was constructed to simulate the CO2 injection process under various sediment temperatures, pressures, and flow rates. The formation of CO2 hydrate and the resulting blockages were investigated in detail through a series of indoor experiments. Due to the increasing driving force for CO2 hydrate formation, reducing sediment temperature and increasing sediment pressure can cause hydrate blockage to form near the injection end, leading to an increase in CO2 injection pressure and a reduction in the storage range. Furthermore, CO2 injection rate has a substantial impact on the pattern of hydrate blockage. A lower injection rate facilitates full contact between CO2 gas and pore water, which helps to increase the formation and blockage degree of CO2 hydrates, thereby decreasing the amount of CO2 injection. The experimental investigation presented in this paper examines the laws of CO2 injection and clogging under various sediment conditions and injection processes on a one-dimensional scale, which can provide valuable insights for the design of CO2 sequestration processes.
