<p>PROBLEM TO BE SOLVED: To efficiently prepare gaseous hydrogen by utilizing waste heat, to store the resultant gaseous hydrogen and to make the gaseous hydrogen arbitrar ily usable when needed. SOLUTION: DC electric power 3 is formed by cascade-constituted geothermal power generation elements 2 utilizing the waste heat of combustion equipment 1, like a waste incineration station 1A or thermal electric power plant 1B, and water is electrolyzed by using the resultant DC electric power 3, by which the gaseous hydrogen 5 is prepared. The prepared gaseous hydrogen 5 is stored by a storage means 7.</p> |
