Over the past century, fossil fuels have provided the majority of China's energy. However, their extensive utilization leads to a shortage and environmental pollution. Recently, submarine and permafrost gas hydrate deposits have been investigated as a possible clean and sustainable energy source...

In November 2008, gas hydrate samples were recovered during the scientific gas hydrate drilling project conducted in the Qilian Mountain permafrost located in the Qinghai-Tibet Plateau, China. This region is expected to become a strategic gas hydrate exploitation area in China. Based on the gas...

The porous microstructure of hydrates governs the mechanical strength of the hydrate-bearing sediment. To investigate the growth law and microstructure of hydrates in porous media, the growth process of tetrahydrofuran (THF) hydrate under different concentration of THF solution is directly...

CO₂ hydrate formation and dissociation is crucial for hydrate-based CO₂capture and storage. Experimental and calculated phase equilibrium conditions of carbon dioxide (CO₂) hydrate in porous medium were investigated in this study. Glass beads were used to form the porous medium. The...

The heat transfer analysis of hydrate-bearing sediment involved phase changes is one of the key requirements of gas hydrate exploitation techniques. In this paper, experiments were conducted to examine the heat transfer performance during hydrate formation and dissociation by a thermal method...

This paper introduces the research advances on replacement of CH₄ in Natural Gas Hydrates (NGHs) by use of CO₂ and discusses the advantages and disadvantages of the method on the natural gas production from such hydrates. Firstly, the feasibility of replacement is proven from the points of view...
