Abstract

 CO2 hydrate storage is considered as the second option in our Co., Ltd. of CO2 underground storage in terms of carbon dioxide capture and storage for countermeasure against global warming. Since, CO2 hydrate storage is controlled by both pressure and temperature, it is very important to know precisely the water depths where seawater temperatures are stable. Then about 1.75 million data around Japan is arranged in seawater temperature–pressure relationship and the relationships are formulated in this paper. The formulations would be used for the site selection of CO2 hydrate storage.
