wolle26Q-Energy Innovator Fellowship統合新領域学府オートモーティブサイエンス専攻 博士後期課程1年次世代燃料電池産学連携研究センター 教授Hydrogen is a clean energy carrier which can be used and produced without carbon emissions. It also carries a significantly larger amount of energy by weight compared to other clean ener-gy carriers, which makes it ideal for heavy-duty transport. How-ever, hydrogen takes up too much space at room temperature and pressure. To counter this, it is often compressed to 70 MPa. This compression incurs significant added costs both for the fueling stations and the vehicles. Another option is liquification, which also incurs significant energy costs.To solve this issue, hydrogen can be stored within the confines of porous carbon materials, where it will reach a higher density than the bulk fluid at a given pressure and temperature due to van der Waals interactions with the carbon surface. This system has been estimated to be able to store a comparable amount of hydrogen as a conventional 70 MPa tank at only 10 MPa, albeit at a lowered temperature of 77 K. Despite its potential, either the operating temperature or the capacity still needs to be improved in order for it to be competitive.However, optimizing porous carbons is difficult because the structure of cheaper amorphous carbon materials are too com-plicated to simulate using computers, while direct control of the structure is not possible via experiments. For example, altering pore volume in an activated carbon will often simultaneously af-fect the pore size distribution. This means any single experimen-tal study will often not be able to clarify the processing-structure-property relationships. As a result, many of the high performing materials in the field have been found via serendipity alone.To be able to rationally design high performing carbon materi-als, we need to characterize the relationships between synthesis parameters, the resulting carbon structures, and their adsorp-tion properties. To do that, I will collect large amounts of data by conducting literature reviews and experiments. Then, I will apply data science techniques to clearly quantify the relationships from the resulting dataset.Additionally, often the study of materials are confined to only the processing-structure-property relationships. However, to de-velop materials that can be used in real applications, we need to also consider how each material property that we measure in the lab will affect the actual system. To that end, I am also conducting studies to simulate the performance of full-scale hydrogen sorp-tion tanks as a function of the sorbent material properties.指導教員からメッセージIrfan has been a member of my group since his bachelor project. It was immediately obvious that he was a gifted student with a strong work ethic. As a testament to his academic prowess, he was able to publish research papers in prestigious journals based on both his bachelor project and masters project – a rare achievement! Comfortable both performing experiments in the lab or developing models on a computer, he has also received several prizes and awards for his clear and insightful presentations. Overall, Irfan has proven himself to be worthy of receiving on this Q-Energy Innovator Fellowship, and I think he has what it takes to succeed in his chosen career path, be it academia or industry.
