Japanese industrial energy storage solar container lithium battery

Are lithium-ion batteries a threat to Japan's Energy Transition?

Lithium-ion batteries (LiBs) have long been the dominant choice for energy storage for grid applications. Despite their widespread adoption, LiBs pose several critical challenges that threaten the sustainability and security of Japan’s energy transition.

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.

Why is energy storage important in Japan?

As Japan accelerates its transition toward a carbon-neutral future, the role of energy storage has become more critical than ever. The country has set ambitious goals to expand its renewable energy capacity, including wind and solar power, to reduce dependence on fossil fuels.

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.
