The technology of the deep-ocean CO2 storage is expected to directly mitigate the source of the global warming. At deep-ocean condition above 4.45 MPa and below 283 K, the CO2 clathrate hydrate crystals are formed as membrane at the interface between the liquid-water phase and the liquid-CO2 phase. Since the strength and the thickness of the hydrate membrane are crucial to the storage period, it is important to experimentally measure the mechanical characteristics of the CO2 hydrate membrane and the hydrate droplet. In the present study, the CO2 hydrate membrane thickness is measured by using the laser-light interference method. It is clarified that the present method by using the beam light interference method is applicable to measure the CO2 hydrate membrane. The hydrate membrane thickness is estimated to be about 7 μm∼12μm at 10MPa and 275 K∼283 K. It is also clarified that thickness of the CO2 hydrate membrane is in proportion to the temperature.
