| Summary: | Abstract Fundamental research and economic analysis of hydrate-based carbon dioxide (CO2) sequestration play a key role in developing the industrialization of oceanic CO2 sequestration. Therefore, this review deals with recent progress in hydrate-based CO2 sequestration from the thermodynamics and kinetics as well as their energy consumption and cost. The first section provides an overview of the thermodynamics of CO2 hydrate formation in both pure water and sea water, establishing a relationship between the enthalpy change of the hydrate formation reaction and the hydrate structure. Subsequently, a comparison of the kinetics of CO2 hydrate formation in pure water and sea water is presented, with further insight into the formation kinetics obtained through hydrate nucleation and growth models. The process of liquid CO2 forming hydrates is summarized, serving as a critical part of the fundamental research for oceanic CO2 sequestration. Finally, energy consumption and cost of CO2 capture methods are compared, and the whole sequestration process cost of CO2 capture-storage-transport-injection is comprehensively analyzed. The new understanding of this review is conducive to further commercial and industrial development of hydrate-based CO2 sequestration. |
