Research and development on renewable energy and systems such as solar, wind, biomass etc.
Background and purpose of establishing the Division
To solve the global warming problem, the biggest issue for humankind in the 21st century, it is necessary to substantially shift the energy sources from fossil energy such as coal, oil and natural gas to renewable energy. With this background, the predecessor Solar Power Generation Technology Division had worked to promote research of the University on solar power generation by disseminating the research results in Japan and worldwide, tackling the global warming problem. Meanwhile, in today world, there is a wide variety of research and development ongoing on “renewable energy” beyond solar, such as wind power, biomass power generation and fuel cells. In addition, at the time of the establishment of the predecessor Division, the power supply was simply based on nuclear power to provide a stable base power and thermal power generation to supplement the fluctuation of demand. However, nowadays many types of renewable energy are connected to the grid and the operation of the system infrastructures for stable power supply has become highly difficult and critical. We have therefore reorganized the Division, which previously focused only on solar, to include the entire “renewable energy”, and defined the purpose of the new Division as following:
( i ) Development of power generation materials that reduce the installation and operation costs to the same level as power generation by fossil fuels.
( i i ) Development of highly efficient management technology for electric power from various power generation methods.
( i i i ) Development of new materials and new system technologies.
( i v ) Collaborations between our research division and external research institutes.
As a research and development hub for renewable energy technology, we will realize novel renewable energy materials and power generation systems through vertical integration of technologies, as well as educate the next generation of researchers and disseminate the technology to society. Specifically, the following activities will be carried out:
Renewable energy materials group:
( i ) Proposal of ultra-high efficiency power generation device by tandem configuration of thin film solar cells/thermoelectric generation elements.
( i i ) Establishment of hydrogen production technology using solar cell thin films and charging technology such as supercapacitors.
( i i i ) Development of ultra-low-cost solar and fuel cell materials and manufacturing methods, and examination of their common basic technology.
Energy management group:
( i ) Development of technologies of failure diagnosis, remote diagnosis, power generation prediction and AI utilization for energy loss control.
( i i ) Integration of smoothing technology development for wind × solar power generation and power storage technology such as batteries and flywheels.
( i i i ) Solar matching for agriculture and application of renewable energy technologies to smart houses.
