The capture and storage of carbon dioxide has been identified as a potential strategy for mitigating global warming. In particular, the use of hydrates for capturing and storing carbon dioxide is being considered. However, it is difficult to transport hydrates because of their low liquidity. In the present study, we attempted to produce a hydrate from an oil-in-water emulsion; the hydrate slurry thus obtained was expected to have high fluidity. Water-in-silicone oil (W/O) emulsions were prepared with the water content ranging from 0.2-0.5 by volume; to these emulsions were added a nonionic surfactant. Reagent-grade carbon dioxide was added to the hydrate emulsions to act as the guest molecule.
