From May 19 to 21, 2026, the first in-person meeting of Phase 2 of the International Energy Agency (IEA) Technology Collaboration Programme (TCP) Hydrogen Task 43 was held in Tokyo, Japan. The meeting brought together 31 experts from academia, industry, and government organizations, including 25 participants attending in person and 6 joining online.
Hosted at Haneda Innovation City “KAWARUBA”, the three-day meeting focused on technical discussions within the various Task 43 subgroups, covering key challenges and opportunities related to hydrogen technologies and safety. Participants exchanged research findings, discussed ongoing activities, and reviewed future directions for international collaboration. An opening message from Japan’s Ministry of Economy, Trade and Industry (METI) highlighted the importance of international cooperation in advancing the safe deployment of hydrogen technologies.
In addition to the technical sessions, participants joined a technical tour of Haneda Innovation City, visited research facilities at the Central Research Institute of Electric Power Industry (CRIEPI) in Yokosuka, and attended a networking reception in Kamakura. These activities provided valuable opportunities for knowledge exchange and strengthened collaboration among researchers and stakeholders from different countries.
Our laboratory contributed to the organization and technical discussions of the meeting and continues to support international efforts to improve the safety and resilience of hydrogen energy systems through research in safety engineering and risk science.
