The heat transportation from a complex of industry to a rural area needs more efficient method because the distance between them is usually more than 10km. Conventional heat transportation using steam or hot water via pipe line has limits in transportation distance (about 3-5 km) because of the heat loss and frictional loss in the pipe line. Metal hydride can absorb or discharge hydrogen through exothermic and endothermic reaction. After releasing hydrogen from metal hydride with heatings by waste heat from industry we can transport this hydrogen to the rural area via pipe line. In the urban areas other metal hydride reacts with this hydrogen and produces heat for heating. Cool heat is also obtained if it is possible to use metal hydride with low reaction temperature. So metal hydride can be used as a media for transportation, storage of heat. Some problems of the heat transportation using metal hydrides, and the example of heat transportation system were discussed.
