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...

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...

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...
