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.

Hydrogen has become increasingly popular as one of the alternative fuels to reduce greenhouse gas emissions. Storing hydrogen in geological structures is a technology that shows great potential in storing large amounts of hydrogen efficiently. However, this technology is relatively new and requires a clear understanding. Therefore, a quick review of underground hydrogen storage is needed to understand its fundamental concepts. This review article presents important components relevant to underground hydrogen storage. First, some currently available hydrogen production methods are discussed followed by hydrogen storage methods. Both small-scale and large-scale hydrogen storage methods are presented. Next, some important factors (fluid properties, rock properties, solid−fluid interactions, and chemical interactions) influencing underground hydrogen storage are summarized. This is followed by presenting various interesting field studies for underground hydrogen storage. Lastly, some challenges and future outlooks pertinent to underground hydrogen storage are reviewed. This article will serve as a useful resource that provides a quick overview of underground hydrogen storage for both researchers and industrialists.

Natural gas hydrate (NGH) has the characteristics of low pollution and large reserves, which is considered as a very promising energy source. The extraction of NGH would cause the strength and stiffness reduced in hydrate-bearing sediment (HBS) reservoirs, which could lead to geological disasters. The mechanical properties of HBS have been studied by a large number of scholars, but it has not been sorted out and summarized for HBS under the influence of multiple factors. In this paper, the hydrate types, synthesis methods, and test conditions are summarized. The effects of hydrate saturation, loading rate, temperature, pore pressure, confining pressure, fine content, and clay content on mechanical properties and deformation behavior of HBS are outlined. The microstructure of the synthesis, decomposition, and shear processes of HBS specimens is also analyzed based on the CT triaxial shear test system, and the microscopic mechanism of HBS specimens in the shearing process is summarized. Finally, the shortcomings of current research on the mechanical properties of HBS are discussed, and provided corresponding suggestions to promote the development of the mechanical properties of HBS.
