Use of Japanese energy storage batteries

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.

Can EV batteries be reused in Japan?

One feature of our grid energy storage system is that it utilizes reused batteries from EVs. Although the penetration rate of EVs in Japan is still only about 1%, the Japanese government aims for 100% of all new passenger car sales to be EVs by 2035. This, at the same time, means that more batteries will be discarded.

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.
