Japanese industrial energy storage device

What is Japan's first energy storage project?

In 2015, we started Japan's first demonstration project covering energy storage connected to the power grid in the Koshikishima, Satsumasendai City, Kagoshima. This project is still operating in a stable manner today. One feature of our grid energy storage system is that it utilizes reused batteries from EVs.

How big is Japan's energy storage capacity?

Global energy storage capacity was estimated to have reached 36,735MW by the end of 2022 and is forecasted to grow to 353,880MW by 2030. Japan had 1,671MW of capacity in 2022 and this is expected to rise to 10,074MW by 2030. Listed below are the five largest energy storage projects by capacity in Japan, according to GlobalData’s power database.

What is Japan's energy storage policy?

As policy, technology, and decarbonization goals converge, Japan is positioning energy storage as a critical link between its climate targets and energy reliability. Japan’s energy storage policy is anchored by the Ministry of Economy, Trade and Industry (METI), which outlined its ambitions in the 6th Strategic Energy Plan, adopted in 2021.

How is Japan's energy storage landscape changing?

Japan’s energy storage landscape is shifting, pushed by household demand, corporate ESG mandates, and domestic battery manufacturing. The residential lithium-ion market, projected to grow at a CAGR of 33.9% through 2030, remains one of the fastest-expanding segments.

How much money does Japan spend on energy storage?

For the scheme ‘Support for the introduction of energy storage systems for home, commercial and industrial use’, the Japanese government has allocated around JPY9 billion (US$57.48 million) from the FY2023 supplementary budget.

Why is Japan focusing on energy storage?

Japan, which targets renewable energy representing 36% to 38% of the electricity mix by 2030 and 50% by 2050, is seeking to promote energy storage technologies as an enabler of that goal. At the same time, electricity demand forecasts for the coming years have risen due to the expected increased adoption of AI and the growth of data centres.
