IMT Seminar Series: Yukitaka Kato - Energy storage best mix for carbon neutral society


JCMB - Lecture Theatre C


Tuesday, September 5, 2023 - 14:00 to 15:00


In order to realize global carbon neutrality (CN), green transformation (GX, changes in industrial and social structures according to CN) is indispensable. Innovation of materials and processes for energy systems will act as key technologies for GX realization and contribute to the construction of a society that coexists with the global environment. Renewable energies are the most important zero-carbon energy resource for the establishment of GX with carbon dioxide (CO2) emission mitigation. However, photo voltaic and wind turbine electric power productions are intermittent, and induce a large amount of power production curtailment occasionally in the world. Some energy storage technologies are required for the establishment of the best energy storage mixed system. We would have choices of energy storage by electric, thermal, thermochemical, chemical, potential, and kinetic storage. Our society needs optimization of energy storage mixed systems for CN. This presentation mentions the potential of every storage technologies and a vision for energy storage best mix for CN society.


Professor Yukitaka Kato, Director of Laboratory for Zero-Carbon Energy (ZC), Institute of Innovative Research, Tokyo Institute of Technology (Tokyo Tech), and Head of Green Transformation Initiative at Tokyo Tech (Tokyo Tech GXI) performed his graduate study in the Department of Chemical Engineering, Tokyo Tech, obtaining his PhD in 1991.

He is majoring researches related on thermal energy utilization for the realization of carbon neutrality by developing thermochemical energy storage and chemical heat pump systems, carbon recycling systems based on CO2 electrolysis, and hydrogen system by using low-cost hydrogen permeation membrane.

He was the Director of the Division of Environmental, Energy and Social Engineering, the Iron and Steel Institute of Japan, the Director of the Division of Energy Engineering, the Society of Chemical Engineers of Japan and the Director, the Division of Industrial Chemical Machinery & Safety Division, The Japan Society of Mechanical Engineers, and an expert from Japan in IEA-ECES Annex 36. He published over 110 peer-reviewed papers, over 30 coauthored books and over 40 patents. He was a Visiting Professor at Massachusetts Institute of Technology, US, in 2017, at Tohoku Univ., Japan, in 2022, and a Research Fellow at the University of Edinburgh, UK, in 1997.
