In terms of research activities, we have undertaken a fundamental study of aluminum waste and acidic geothermal hot spring water reactions for producing hydrogen in both lab-scale and onsite designs. The study revealed that strong acidity, elevated temperature, and higher chloride-containing hot springs effectively disrupted the aluminum surface's oxide layer. Therefore, aluminum's surface morphology became rougher and pitted, which allowed water to penetrate deeply and drastically enhanced aluminum reactivity with water to release hydrogen.We have also conducted a life cycle assessment to evaluate the environmental impact of the system studied. As a result, hydrogen fuel use from aluminum waste materials-acidic hot spring reactions reduced environmental impacts (i.e., carbon emission and energy consumption) compared to gasoline and primary aluminum use. The negative CO2 emission results reflected emission reduction due to hot spring neutralization (replacing limestone input).As for research output, we have published the journal article, performed collaborative work relevant to the future research direction, and made presentations at academic meetings.We are currently exploring treatments on aluminum (and some potential metals) to generate more hydrogen effectively, clarifying the possible impurities, working on a techno-economic assessment of the system, and preparing for presentations and relevant publications.

在研究活动方面，我们在实验室规模和现场设计中进行了铝废料和酸性地热温泉水反应制氢的基础研究。研究表明，强酸性、高温和含氯量较高的温泉有效地破坏了铝表面的氧化层。因此，铝的表面形态变得粗糙和凹坑，这使得水能够深入渗透，并大大增强了铝与水的反应性以释放氢。我们还进行了生命周期评估，以评估所研究系统的环境影响。因此，来自铝废料的氢燃料使用-酸性温泉反应减少了环境影响（即，碳排放和能源消耗）与汽油和原铝的使用相比。负CO2排放结果反映了由于温泉中和而减少的排放（替代石灰石投入）。在研究成果方面，发表了期刊论文，进行了与未来研究方向相关的合作，并在学术会议上发表了演讲。目前正在探索铝的处理方法。（和一些潜在的金属）有效地产生更多的氢，澄清可能的杂质，对系统进行技术经济评估，并准备介绍和相关出版物。
