Development of Renewable Energy Systems for Sustainable Development Society



Development of renewable energy systems as well as research on high efficient energy conversion systems is a key technology to solve the global-scale environmental destruction and energy problems. We are working on the research on the advanced technology of renewable energy such as solar energy and hydrogen. Topics of research are two of the following roughly separately. 
(1) Development of highly effective thermal energy systems and energy saving systems by using spectral control of thermal radiation. 
(2) Aiming at the achievement of the hydrogen energy society, we develop new energy conversion devices based on solid state ionics, and perform feasible studies for solid oxide fuel cells (SOFCs) based on mechanics of materials.

Targeted Application(s)/Industry

High temperature solar absorption materials
High effieciency solar-termophotovoltaic (STPV) system
Small power source for mobile electric devices based on micro-SOFC
