The demand of natural gas is expected to increase because of its environmental superiority. Therefore the importance of the stable supply, reserve and storage is anticipated to increase. Natural gas has been stored in underground reservoir as gas phase or in tanks as liquid phase by now. In this study we proposed the natural gas stockpiling system with natural gas hydrate tank which uses cold energy of LNG plant and executed the computer simulation and the experimental verification of the heat transfer characteristic in the hydrate tank and preservation characteristics in methane hydrate. <BR>In the simulation of the heat transfer characteristic, macro heat conduction has increased with the increase of the packing ratio and the adfreezing radius of the NGH pellet. Moreover, it was suggested that the influence by convection be larger than that by the heat transmission between pellets in the tank. In the experiment on the macro thermal conductivity with the ice pellet in random packing, it was suggested that there be a difference of the macro thermal conductivity of about 20% when even the pacing ratio was the same. In the preservation experiment at a temperature of under -80°C (-85°C, -135°C) in methane, hydrate was able to preserve with a low dissociation rate, under 0.1% per day. Finally, it was suggested to have to make the NGH tank at a low price in the approval of the proposed system.
