CO2 hydrates are a class of gas hydrates as well as natural methane hydrates vastly exist in subsea area. Recently, CO2 hydrates are attracted much attention as a key technology for hydrate based CCS since there are a lot of options for CCS sites. In this commentary, we provide basic information for gas hydrates especially for CO2 hydrates and introductory of CO2 hydrate based applications including CO2 capture, CO2 sequestration and their processes.
