Title:
廃熱利用水素製造装置および廃熱利用水素製造方法
Document Type and Number:
Japanese Patent JP5710142
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydrogen production apparatus and a hydrogen production method by which hydrogen as a chemical energy with easy storing property can be efficiently and stably produced by using thermal energy, which easily diffuses, so as to effectively use energy.SOLUTION: The hydrogen production method includes steps of: carrying out thermoelectric power generation by installing a thermoelectric power generator (thermoelectric conversion module 11) having a thermoelectric element having a high durable temperature, in a place such as a blast furnace where repeated thermal cycles are relatively few and waste heat at a high temperature is stably obtained through the year; also using the waste heat to convert water from a water supply tank 21 into high temperature steam at about 1,000°C or medium temperature steam at about 600°C by a steam generator (a steam heater 12 and a heat exchanger 14); then electrolyzing the steam to produce hydrogen and oxygen by an electrochemical device (electrolytic device 13) using the generated power; and storing the produced hydrogen and oxygen in a hydrogen tank 23 and an oxygen tank 24, respectively.
