The research projects at the Energy and Environmental Systems (EES) laboratory focus on identifying strategies and policies to address long-term energy-related issues, including global energy supply and environmental challenges facing our society. We aim to achieve this by developing analytical methods and utilizing computational models to understand the role of science and technology in shaping better energy and environmental policies at all levels. Our team of researchers, with diverse backgrounds, works on designing an appropriate decision-making framework that evaluates future scenarios from both macro and micro perspectives. This framework can help create a sustainable energy system for Japan, Asia, and the world.

With the aim of developing attractive next-generation energy systems, we are engaged in education and research in the fields of chemical engineering such as process engineering and thermal mass transfer engineering. Through fundamental experiments, we try to model chemical reactions and mass transfer phenomena, and then to use numerical simulations to pursue optimal systems. In the development area of ​​most advanced science and technology, there are many situations in which it is difficult to predict phenomena based on just conventional knowledge.In our laboratory, we are challenging to correctly understand and model mass transfer phenomena occuring in special environments such as the interface between plasma or supercritical CO2 and solid walls, the flow field of high-temperature melts (liquid metals and molten salts), and the field of nuclear transmutation reaction by neutrons. Additonally, we are also actively studying on the hydrogen production using solid electrolyte cell or plasma, and environmental dynamics of tritium, which is a radioactive hydrogen isotope. These scientific achievements will be useful for the realization of nuclear fusion reactors, next-generation fission reactors, and a society utilizing hydrogen energy and renewable energy.

To solve environmental problems with bringing meningul provisions to our society, we should model complex systems as literally they are, not to much simplified. For ensuringn such modeling, we do need to take a bottom-up approach not relying on a conventional analytical approach from top-down viewscope. In the laboraotory, we explored various studies with intensive scientific passions so as to clarify the mechanisms of 'Human-Environemnt-Social system' by employing applied mathematics and social physics underpined by complex science, evolutionary game theory, non-linear dynamics and multi-agent simulation.

Space is filled with plasma. In our heliosphere the main source of plasma is the sun. Magnetospheres of planets are connected with the sun via the plasma filling the interplanetary space. Their behaviour is influenced in many ways by solar activity. The heliosphere itself is exposed to interstellar space which is also filled with interstellar plasma... We study a variety of space environments from near Earth to distant high energy objects. We also work to develop the propulsion techniques of spacecraft by controlling plasma.
