- Japan plans to increase Green Innovation Fund support for next-generation batteries.
- Field trials of perovskite solar cells will expand across public infrastructure.
Japan Expands Green Innovation Fund for Clean Energy Technologies
The Japan METI Green Innovation Fund will be expanded starting in fiscal year 2026 to accelerate the commercialization of next-generation energy technologies. Japan’s Ministry of Economy, Trade and Industry plans to increase support for advanced storage systems, particularly all-solid-state batteries, while also promoting deployment of perovskite solar cells. The initiative forms part of the country’s long-term strategy to achieve carbon neutrality by 2050 through large-scale industrial innovation and clean technology adoption.
Focus on Solid-State Batteries and Advanced Storage
Funding adjustments for next-generation batteries will reflect rising raw material costs and evolving technology requirements. The program supports multiple industry participants involved in battery development, materials engineering, and recycling technologies. Companies participating in these initiatives include Honda, Nissan, and GS Yuasa, alongside Idemitsu Kosan, all contributing to the advancement of safer and higher-performance battery systems.
Role of NEDO in Industrial Innovation
The Green Innovation Fund was established in March 2021 under the New Energy and Industrial Technology Development Organization (NEDO). Its purpose is to support long-term projects that help industries transition toward zero greenhouse gas emissions. By backing collaborative development between manufacturers and material suppliers, the program aims to accelerate practical deployment of emerging energy technologies.
Infrastructure Trials for Perovskite Solar Cells
In addition to battery development, METI plans to support field demonstrations of perovskite solar cells across public infrastructure such as roads and railways. The ministry’s expert committee is expected to review funding allocations for solar projects around April, while battery-related budget adjustments will be examined from May. These measures are intended to strengthen Japan’s clean energy ecosystem while supporting industrial competitiveness and sustainable transportation technologies.
