Japan India Storage Battery Cooperation Agreement Strengthens Battery Supply Chain

Japan and India have strengthened their cooperation in the battery sector after signing a new agreement designed to accelerate collaboration across the storage battery ecosystem. On July 2, Ryosei Akazawa, Minister of Economy, Trade and Industry (METI), and H.D. Kumaraswamy, India's Minister of Heavy Industries, signed a Memorandum of Cooperation (MoC) covering storage batteries. The initiative seeks to improve investment conditions, encourage technical cooperation, and reinforce long-term industrial partnerships between the two countries.

The Memorandum of Cooperation establishes a framework for closer collaboration through public support measures, regulatory improvements, and initiatives that simplify barriers affecting investment and technology partnerships. It also emphasizes the protection of intellectual property rights and confidential information while encouraging stronger engagement with regional governments and other local stakeholders. These measures are intended to create a more predictable business environment that enables companies from both nations to expand cooperation across the battery value chain.

Key Objectives of the Japan-India Storage Battery Cooperation

The agreement is designed to strengthen the battery supply chain while supporting broader industrial collaboration between both countries. It also creates opportunities for businesses to participate in future battery manufacturing, technology development, and supply chain expansion.

• Promote public support measures for battery projects.
• Reduce regulatory barriers affecting investment.
• Strengthen technical collaboration between industries.
• Protect intellectual property and confidential information.
• Build partnerships with regional governments and stakeholders.
• Support Japanese companies expanding into the Indian market.

Projected Growth in India's Battery Storage Demand

India continues to experience strong demand for vehicle electrification, particularly across two- and three-wheelers. At the same time, the growing deployment of renewable energy is expected to significantly increase the requirement for utility-scale battery storage systems. According to the information shared, battery storage demand is projected to reach approximately 300 GWh by 2030, representing nearly a tenfold increase compared with current levels. These market trends provide substantial opportunities for international collaboration in manufacturing, technology, and supply chain development.

India Battery Storage Market Outlook

Collaboration between both countries has been progressing beyond this latest agreement. In July 2025, the Japanese government visited India with more than 30 Japanese battery-related companies to organize an event focused on batteries and critical battery minerals. The discussions explored collaboration opportunities involving India's public and private sectors, laying the foundation for deeper industrial partnerships. The newly signed Memorandum of Cooperation further reinforces these ongoing efforts and is expected to strengthen future cooperation across the battery ecosystem.
