Hydrate-based CO 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 storage are summarized. Furthermore, research progress and shortcomings of hydrate-based CO storage are analyzed. The two main methods for hydrate-based CO storage are direct CO hydrate storage and CO–CH hydrate replacement. Direct CO hydrate storage on the seabed and in the subsea (or permafrost) is proposed, and CO 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–CH replacement is preferred because it combines the benefits of CO storage and CH production. The hydrate equilibrium of different CO–CH mixture hydrates is measured using different methods. Nuclear magnetic resonance and Raman spectroscopy are commonly used to study the hydrate structure characteristics and mass transfer properties. Macrokinetics are usually conducted in a high-pressure vessel to analyze the effects of the experimental conditions on the replacement results. Nevertheless, the replacement rate and hydrate properties should be investigated further.
