Our laboratory conducts integrated research to promote the sustainable circulation of resources and energy, focusing on biomass methane fermentation, gas storage technologies for energy gases such as methane and hydrogen, as well as greenhouse gases, using porous materials, and biomethanation technologies. Because these topics are closely tied to sewer systems, water environments, and the circular use of wastewater and solid waste, we approach them as interconnected challenges. In addition to fundamental research on campus, we also conduct pilot-scale experiments in collaboration with external partners. The photograph shows a molded gas storage body made from porous materials synthesized in our laboratory, enabling high gas storage in a small volume.
