A thermochemical hydrogen production process named UT-3 was proposed in combination with solar energy.Some amounts of water steam were produced from a solar collector at 800ﾟC,and then introduced directly into four reactors which were heated adiabatically. This method using adiabatic reactors showed a great possibility for improving thermal efficiency over 50% in comparison with conventional type of reactors heated from outside reactor walls.It was found that the bypass of a certain amount of water steam is needed to obtain good conversion of a reaction from consideration of its reaction equilibrium. In addition to solar heat, the possibility for utilizing discharged heat of coal-fired power stations and blast furnaces was studied, and the result will be presented at 11th World Hydrogen Energy Congress to be held in Argentine. The publication of a book about hydrogen energy written by E.Bligen and K.Yoshida is also in progress.

结合太阳能提出了一种名为UT-3的热化学制氢工艺。该方法利用绝热反应器，从太阳能收集器产生一定量的800℃的水蒸汽，然后直接引入四个反应器中进行绝热加热。与从反应器壁外加热的传统类型反应器相比，显示出热效率提高50%以上的巨大可能性。综合考虑，发现需要一定量的水蒸汽旁路才能获得良好的反应转化率除了太阳能热之外，还研究了利用燃煤发电站和高炉排出的热量的可能性，其结果将在阿根廷举行的第十一届世界氢能大会上公布。 E.Bligen 和 K.Yoshida 撰写的一本关于氢能的书也在编写中。
