Main Research

Research on developing and modelling of biohydrogen production and hot-gas cleaning
Research and development of biohydrogen production through biomass gasification and hot-gas cleaning. Furthermore we conduct a modelling of the systems via dynamic simulators or process design simulators.
Environmental evaluation of biomass energy systems from a Life cycle assessment perspective
Life cycle assessment of environmental energy systems are implemented for environmental benign society by minimisation of carbon dioxide.
Contaminated woody biomass utilisation for bioenergy and behaviour radionuclide
Regional woody biomass utilisation for power generation lead to employment creation and forestry vitalisation. In Fukushima, for the woody biomass use, radioactive substances behaviour during contaminated woody biomass gasification is required. The radiocaesium behaviour is investigated before now.
Mapping of biomass resource in Fukushima
For appropriate utilisation of the biomass resource in Fukushima, the biomass generated in Fukushima is investigated.
Experimental Apparatus
GC-TCD(Inorganic gas analysis), GC-FPD(sulfuric compounds analysis)、TG-DTA(with steam supply), Gasification test setting, Supercritical water continuous reaction equipment, Salt bath (bach reactor test), Microwave equipment, etc...

Introduction of Laboratory

The endowed chair was created at ​Faculty of Symbiotic Systems Science, Fukushima University. It contains four kinds of chairs: Biomass, Geo-heat, Solar and Hydraulic. The members of the biomass lab conduct biomass gasification and methane fermentation for hydrogen, power and biofuels production from the perspective of experiments, modeling and life cycle assessment (LCA).
