PURPOSE:To make it possible to perform stable utilization of heat at a high temperature level in a solar heat storing apparatus, by using one of two hydrogen storing containers having independent heat exchangers for long-period heat storage and using the other for short-period heat storage. CONSTITUTION:The heat medium, which is heated by a solar heat collector 11, is circulated through a transporting pipe 12 by a pump 18. A heat medium in a transporting pipe 15 is heated in a heat exchanger 14, and the heated heat medium is circulated through the transporting pipe 15 by a pump 20. The excessive heat yields hydrogen gas in a heat storing device 1, and the gas reaches a hydrogen storing container 3 through an opening and closing valve 5. When the hydrogen in the hydrogen storing container 3 is saturated, the opening and closing valve 5 is closed and an opening and closing valve 4 is opened. Then hydrogen is stored in a hydrogen storing container 2 for long-period heat storing. Since the two hydrogen storing containers are selectively used as required at the time heat radiation, fluctuation in the amount of the thermal load can be quickly processed. |
