Experimental Studies on Gas Hydrate‐Based CO 2 Storage: State‐of‐the‐Art and Future Research Directions
Hydrate‐based CO 2 storage is considered a potentially effective way of reducing greenhouse gas emissions and slowing down global warming. Herein, the locations in the ocean and permafrost that meet the requirements for hydrate‐based CO 2 storage are summarized. Furthermore, research progress and sh...

Hydrate‐based CO 2 storage is considered a potentially effective way of reducing greenhouse gas emissions and slowing down global warming. Herein, the locations in the ocean and permafrost that meet the requirements for hydrate‐based CO 2 storage are summarized. Furthermore, research progress and shortcomings of hydrate‐based CO 2 storage are analyzed. The two main methods for hydrate‐based CO 2 storage are direct CO 2 hydrate storage and CO 2 –CH 4 hydrate replacement. Direct CO 2 hydrate storage on the seabed and in the subsea (or permafrost) is proposed, and CO 2 formation experiments on different scales are conducted. Various porous media are used to simulate the natural sediment and investigate the hydrate formation equilibrium and kinetics. CO 2 –CH 4 replacement is preferred because it combines the benefits of CO 2 storage and CH 4 production. The hydrate equilibrium of different CO 2 –CH 4 mixture hydrates is measured using different methods.
