There is a significant difference in the amount of biogas which is produced from sewage treatment process between summer and winter. Therefore, an efficient storage method is necessary for the effective utilization of biogas. The hydrate storage system using the snow is expected as an energy saving method. In the study, gas hydration was investigated as the influence of bulk density of ice layer in the formation and ambient temperature in the storage. As the results of the experiment, it was found that the optimum bulk density for the formation was 0.69g/cm^3 and the ambient temperature of 0℃ was suitable for the storage. And, it was also found that the required energy of the hydrate storage could be reduced from that of the compressed gas storage when the snow was used as a host material of hydrate formation.
