本学発"多孔質体挿人により性能改善した微生物発電"の その後の社会実装に向けた展開

Further development toward social implementation of "microbial power generation with improved performance by inserting porous materials" invented by our university

While working at Sanyo-onoda City University, the author researched and invented the microbial fuel cell utilizing inorganic porous materials, which has a power generation capacity ten times greater than conventional ones. This achievement is attracting attention as an innovative technology that has the potential to replace or supplement the current electrical energy dependence on fossil fuels. After retiring from university, the author wanted to put the research results achieved at the former Morita laboratory into practical use in order to make a significant contribution to humanity's energy problems. Then, the author conducted the cooperating company in Tottori Prefecture that manufactures inorganic porous materials to carry out practical tests in a fallow field on the outskirts of Tottori City. From 2022 to 2023, 64 experimental microbial fuel cells were installed at the test site, and outdoor power generation data was obtained across seasons. During this period, we also conducted in the laboratory experiments to improve power generation and made improvements to problems that emerged during operation in natural environments. Furthermore, during this period, the electricity generated was used to light street- lamps and used for illumination during Christmas and cherry blossom viewing seasons, bringing us one step closer to practical application. At present, microbial power generation has not yet reached the point where it can replace commercial electricity, but it is suitable for use in remote areas, remote islands, and developing countries where electricity is not available, and as an emergency power source during disasters such as typhoons and heavy rain that have been occurring frequently in recent years. We believe that this technology can be put to practical use as a suitable power source in the situations described above.
