14:05-15:05 Prof. Joey D. Ocon, University of Philippines Diliman (50+10 min) 再エネの社会実装
“Energy Transition in Off-Grid Islands: From Least Cost to a Net-Zero System”
Archipelagic countries like the Philippines and Indonesia rely on diesel generators to power small off-grid islands. The dependence on diesel for power generation leads to high greenhouse gas emissions, high power generation cost, and unreliable electricity when supply of diesel is difficult. In this talk, Prof. Ocon will discuss the role of renewables and emerging enabling technologies like batteries and hydrogen in the clean energy transition, including their group’s systems-based research approach.
15:05-15:30 Prof. Julie Anne D. del Rosario, University of Philippines Diliman (20+5 min) 水電解水素製造
“Influence of Electrolyte Cations on Oxygen Evolution Reaction”
Oxygen reactions often limit the electrochemical reactions due to its sluggish kinetics. In alkaline media, the alkali metal (AM) cations are expected to behave as spectator ions and does not affect the reaction kinetics. In her study, however, Dr. del Rosario highlights that the influence of AM cations on the electrical double layer (EDL) structure and interfacial interactions are crucial for high-efficiency oxygen reactions.

15:40-16:05 Prof. Nobuko Hanada, Waseda University (20+5 min) 水素エネルギー
“Development of hydrogen storage and supply process using high content hydrogen storage media”
Practical technologies for hydrogen storage and supply system with high gravimetric and volumetric hydrogen densities need to be established. Focusing on magnesium as a solid hydrogen storage material and ammonia as a liquid hydrogen storage medium, we have developed each hydrogen storage and supply process.
16:05-16:30 Dr. S. Anantharaj, Waseda University (20+5 min) 電気化学エネルギー変換
“Self-supported 1D CuO/OH Nanostructures: Pushing the Limits in Fabrication and MOR Electrocatalysis”
One-dimensional CuO-OH nanostructures offer excellent activity toward MOR in alkali. However, there are several issues in accessing these materials as self-supported in an efficient manner. This talk will highlight some of our recent work on the electrochemical anodization of Cu substrates and their use in MOR electrocatalysis in alkaline waters.
16:30-16:55 Dr. S. Natarajan, Waseda University (20+5 min) LIBアップサイクル
“Recycling spent Li-ion batteries (LIBs) electrodes into high performance LIB electrodes”
The development of economical recycling methods for spent Lithium-ion batteries (LIBs) is very crucial and leads us to regenerate the electrode materials via efficient recycling technologies. In this view, cathode and anode recycling has been performed by direct recycling technologies to reuse them as high-performance electrode materials for the fabrication of new LIBs. This sustainable recycling strategy offers high environmental benefits and high economic returns.
16:55-17:20 Dr. H.Y. Teah, Waseda University (20+5 min) 再エネ技術のLCA
“Life cycle assessment supports environmentally-friendly technology development: case of lithium-sulfur battery and thin-film silicon solar cell”
To develop a green technology, experimentalists must not only focus on the technical performance but also the environmental consequences of the decisions. In this presentation, we applied life cycle assessment (LCA) to quantify the anticipated environmental impact of emerging technologies—based on experiments in our laboratory—to better inform the experiments.
