Summary of "HOW CAN JAPAN HELP CREATE A SUSTAINABLE HYDROGEN SOCIETY IN ASIA?"

Introduction

The paper examines Japan's hydrogen policies and their implications for creating a sustainable hydrogen society in Asia. It highlights that while Japan is a leader in hydrogen technology, its policies lack clarity on transitioning to green hydrogen, which could hinder climate goals and regional cooperation.

Key Findings

• Hydrogen's Potential and Barriers: Hydrogen can decarbonize hard-to-electrify sectors like transportation and industry. However, barriers include high production costs, lack of infrastructure, and unclear policy support for green hydrogen, which is essential for net-zero emissions.
• Japan's Policies: Japan's hydrogen strategy emphasizes expanded use of hydrogen but remains ambiguous about transitioning to green hydrogen. This could limit international cooperation and local benefits.
• Benefits of Transitioning to Green Hydrogen: A shift to green hydrogen can strengthen energy security, align with Japan's international climate commitments, and support local revitalization by fostering economic growth and innovation in rural areas.
• Japan's Role in Asia: Japan's advanced hydrogen technologies and R&D capabilities position it to lead in Asia through co-innovation, enabling mutually beneficial collaborations and accelerating the global transition to clean energy.

Recommendations

1. Provide greater clarity in national policies, including precise language and milestones for transitioning to green hydrogen to enhance credibility and support climate goals.
2. Strengthen links between hydrogen policies and local revitalization strategies to leverage economic and social benefits.
3. Enhance Japan's international climate strategies by focusing on sustainable hydrogen supply chains and co-innovation to promote regional cooperation in Asia.
4. Allocate a portion of pledged funds (e.g., from Kishida's climate initiative) to support green hydrogen development and deployment in Asia, including capacity building and infrastructure.
5. Encourage collaboration with Asian developing countries through joint research, technology transfer, and policy harmonization to build a sustainable hydrogen economy.

Conclusion

The paper concludes that Japan can play a pivotal role in Asia's hydrogen transition by addressing policy ambiguities and fostering regional co-innovation, but failure to clarify green hydrogen support risks delaying climate progress and regional opportunities.
