PURPOSE: To provide a system capable of making use of relatively low-grade heat having tended to be discarded so far.
CONSTITUTION: This system is equipped with a culturing device 7 to culture hydrogen-generating ultrathermophilic bacteria using an organic matter as nutrient in an anaerobic atmosphere at temperatures higher than normal temperatures, a culturing temperature-maintaining mechanism 8 to maintain the culturing device 7 at a temperature suitable for the proliferation of the bacteria through heat supply from a waste heat holding medium at ≥80°C discharged from a waste heat source, and an organic matter feed mechanism 18 to feed the culturing device 7 with organic matter necessary for proliferating the bacteria, and furthermore, a hydrogen storage tanks 14 to store the hydrogen generated in and drawn from the culturing device 7 by proliferating the bacteria so as to enable the drawing of hydrogen from the tanks.
