Japan and china energy storage battery technology

Why is battery storage important in Japan?

They store solar power for use at night and ensure a steady green energy supply, crucial for Japan’s sustainability goals and the Green Transformation (GX) initiative. In short, battery storage is now crucial due to the boom in solar power and the increasing demand for green energy from emerging industries.

Are batteries commercialised in Japan?

batteries are commercialised. Japan imports about 90% of its primary energy requirements and is vulnerable to energy supply disruptions overseas. In recent years, new energy security factors have been studied.

What is Japan's storage battery industry strategy?

The “Storage Battery Industry Strategy” document from METI sets out three key targets: Boost Domestic Manufacturing: Japan aims to ramp up its domestic production of automotive storage batteries to 100 GWh by 2030, with a long-term goal of reaching 150 GWh annually. This move highlights the potential for foreign companies to invest in Japan.

When did Japan start funding lithium-ion batteries?

As an early technology leader, Japan began funding lithium-ion batteries, especially the development of solid-state batteries and certain types of alternative batteries. Total battery funding by NEDO between 2009–2022 (for Solid-EV and RISING 1, 2 and 3 projects) is estimated by ca. 58 billion yen.

What role do batteries play in Japan's future?

This strategy highlights three game-changing roles for batteries: 1. Driving Carbon Neutrality: Japan aims to achieve carbon neutrality by 2050, with electrification at the forefront. Think electric cars, buzzing with the latest battery tech, paving the way to a greener future. 2.

Are China and South Korea tailgating in battery commercialization?

According to Taipei-based intelligence provider TrendForce, China and South Korea were tailgating in commercialization behind Japan’s subsidy of over $660 million for all-solid-state batteries in 2024. In the 2024 Battery Industry Strategy, Japan set a target of commercializing all-solid-state batteries (ASSB) by around 2030.
