Hydrogen gas generation from water in the temperature range of 10–60 °C using iron and carbon dioxide was studied. During the reaction, carbon dioxide consumption and hydrogen generation were observed, and the stoichiometry of the redox reaction with iron carbonation was checked. The rate of the reaction steadily increased with the temperature, and the time required to consume half of the carbon dioxide at 60 °C was less than one-fifth of that at 10 °C. The activation energy was determined by examining the temperature dependence of the reaction rate. Carbon dioxide used in the reaction precipitated as carbonate in the aqueous phase, covering the raw material iron and hindering the progress of hydrogen generation reaction. Experiments following the same procedure were performed using steel and sludge from steel processing, which contained elements other than iron, to show that hydrogen generation and carbon dioxide fixation were also possible.

研究了使用铁和二氧化碳在10–60°C的温度范围内从水中产生氢气。反应期间，观察到二氧化碳的消耗和氢的产生，并且检查了具有铁碳酸化的氧化还原反应的化学计量。反应速率随温度稳定增加，在60°C消耗一半二氧化碳所需的时间少于在10°C消耗五分之一的时间。通过检查反应速率的温度依赖性来确定活化能。反应中所用的二氧化碳在水相中以碳酸盐的形式沉淀，覆盖了原料铁并阻碍了氢生成反应的进行。使用钢铁加工过程中的钢铁和污泥按照相同的程序进行实验，
