Abstract:

In the era background of carbon dioxide emission peak and carbon neutrality, hydrogen energy was the key to energy transformation as clean and green energy. Therefore, hydrogen storage technology as an intermediate bridge between the production and application of hydrogen energy has attracted much attention. Although clathrate hydrates are potential hydrogen storage materials, the slow hydrogen storage rates and low storage capacity hinder its industrialization. Consequently, this work discussed the progress of the kinetics enhancement technology of hydrogen storage in clathrate hydrates, and the kinetics mechanism of hydrogen hydrate nucleation and growth, including the kinetics enhancement technology of hydrogen hydrate (the driving force, the contact area of the gas-liquid interface, and the diffusion channel). Then, we summarized current kinetics enhancement technology from the aspects of hydrogen storage rates and density to support the development of related research. Notably, this paper emphasizes that corresponding works may be performed in the future. First, to deepen research on nucleation, growth, and the stability mechanism of hydrogen hydrate. Second, to seek high efficiency and high driving force thermodynamic promoters in improving driving forces fundamentally. Finally, to combine high-efficiency thermodynamic promoters and improved diffusion channels in achieving the double optimization of high hydrogen-storage rates and storage capacity.
