Technical FAQs 4

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.

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.

How big is Japan's battery storage market?

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.

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.
