Energy systems around the world are undergoing profound transformation as the demand for clean, reliable, and sustainable energy continues to grow. The development of hydrogen technologies, the advancement of renewable energy systems, and the innovation of functional and sustainable materials are becoming increasingly interconnected. Addressing the challenges associated with this transition requires not only progress within individual research fields, but also closer collaboration across disciplines, technologies, and sectors.

The International Symposium on Hydrogen Energy, Renewable Energy and Materials (HEREM) provides an international forum for researchers, academics, engineers, industry professionals, and other experts to exchange knowledge, present recent advances, and explore emerging developments in these interconnected fields. Through successive editions, HEREM has continued to bring together contributions from diverse research communities, encouraging scientific discussion and collaboration across the boundaries of energy science, materials research, and engineering.

HEREM covers a broad range of topics, including hydrogen production, storage and utilization; fuel cells and hydrogen-based energy systems; renewable energy generation and conversion; energy storage and integration; advanced functional materials; catalysis and electrochemical technologies; sustainable materials and manufacturing; and related developments in chemical engineering, energy systems, and environmental applications. By embracing both fundamental research and practical applications, the symposium aims to encourage connections between materials design, technological innovation, system development, and real-world energy challenges.

A central objective of HEREM is to foster meaningful academic exchange and interdisciplinary collaboration. The symposium provides opportunities for participants to share research findings, discuss scientific and technical challenges, exchange perspectives on emerging technologies, and identify potential directions for future research. It also seeks to strengthen connections between universities, research institutions, and industry, supporting the exchange of ideas between fundamental science and engineering practice.

The 13th International Symposium on Hydrogen Energy, Renewable Energy and Materials (HEREM 2027) will be held in Osaka, Japan, from November 18 to 20, 2027. Building on the spirit of previous editions, HEREM 2027 welcomes researchers and professionals from around the world to contribute their knowledge, engage in constructive scientific discussions, and explore collaborative opportunities toward the development of cleaner energy technologies and more sustainable materials.

We look forward to welcoming the international research community to HEREM 2027.
