Japan Energy Storage Policies and Market Overview
Japan''s energy storage policies, market statistics, and trends—from METI''s strategic plans and subsidy programs to deployment challenges.
Various battery technology types are represented in Japans energy storage landscape. These range in diversity, from large-scale NaS sites with output capacity of up to 50 mW, to wind-farm-based VRFB facilities, to a 600 kW facility built of aggregated Li-ion electric vehicle batteries.
In terms of implications for Japans energy storage markets, it bears mention that the Technology Roadmap for Stationary Battery, explicitly includes various scale-levels including integration of utility/grid-level energy storage, middle-scale CEMS and FEMS systems, and small-scale BEMS and HEMS.66 Japan's East-West Grid Division
At the residential level, where battery storage capacities are projected at 100,000 to 250,000 kW, life-span is also projected to increase 50 to 100%. Other small-scale uses, such as data center backup energy storage are projected by NEDO to become commercially widespread in Japan before 2020.
In the commercial space, Japan's battery storage market was valued at USD 593.2 million in 2023 and is projected to reach USD 4.15 billion by 2030. While commercial installations currently dominate revenues, industrial adoption is expected to scale faster. Utility-scale storage is also gaining ground.
