PURPOSE:To enable small-scale power generation by means of small-size equipment by turning a gas turbine by using a hydrogen gas flow, which is obtained by utilizing hydrogen pressure difference that is produced by heating or cooling metallic hydride through switching a high temperature heat source and a low temperature heat source at a constant cycle. CONSTITUTION:When change-over valves 22, 24, 26, and 28 are set as shown in the figure, both a high temperature thermal medium from the high temperature heat source 18 and a low temperature thermal medium from a low temperature heat source 20 are supplied to heat exchangers 14 and 16 for metallic hydride, respectively. Accordingly, in the heat exchanger 14, the metallic hydride releases hydrogen gas, and the hydrogen gas pressure rises. On the other hand, in the heat exchanger 16, the metallic hydride absorbs hydrogen gas, and the hydrogen gas pressure lowers. If valves 34 and 44 are kept open while valves 36 and 42 are kept closed under this circumstance, hydrogen gas flow, which passes through pipes 30 and 40, is formed owing to the difference in hydrogen gas pressure. This hydrogen gas flow drives a gas turbine 12, and the electric power is generated by a power generator 10. |
