With the global demand for virtually zero greenhouse gas emissions by 2050, science and technology are facing major challenges as to how to tackle this challenge. Even under these circumstances, building a bright future while achieving sustainable growth can be said to be the greatest challenge required for future science and technology.

In order to realize such a society, research and development within the academic system that has been vertically divided up to now cannot cope with it. In other words, it is essential to establish an innovative theoretical system that can cross different energy conversion engineering systems of electrical system, mechanical dynamical system, and thermal energy system. For more than 50 years, our research group has been the first in the world to show that energy system analysis can be unified with circuit theory as a common analysis structure even between different engineering systems.

We have applied this theory and developed heat pumps and other heat energy systems through a number of fundamental studies that have served as the basis for equipment development, and have materialized them as equipment. In the future, we will expand the scope of application from energy supply networks, including the "hydrogen energy supply chain," "locally produced energy for local consumption," and "renewable energy," which are essential for the realization of a decarbonized society, to "living space," "production technology," and "agricultural and food management" on the demand side. Our research group will present the future of the energy society to the world by conducting basic research as well as developing concrete systems.

By 2050, there are only 30 years left. It is an era when you are the center of society. It is up to you to create a bright future society.
