To build up the hydrogen energy society, hydrogen compression process is needed to be highly efficient. To construct highly efficient hydrogen compression process, chemically hydrogen compression process by redox reaction of iron oxides is focused on in this study. This process can be driven only by factory waste heat and it has higher thermal efficiency than mechanical hydrogen compression. In this process, reaction rate of deoxidization is investigated with changing reaction temperature and existence of steam. From our results, low temperature reaction rate of iron deoxidization is largely inhibited by the existence of steam. However, its reaction rate is restored by rapid removal of steam. It is clear that low temperature activation of deoxidization is achieved by rapid removal of steam.
