Summary: Chinese battery companies are expanding production capacity to 900 GWh per year, mainly for Battery Energy Storage.

Chinese battery makers announced plans in early 2026 to add over 600 GWh of new production capacity for the energy storage system (ESS) market, with the total buildout reaching 900 GWh annually once complete — roughly ten times the 58 GWh installed across the entire US in 2025.

Around 70% of the new capacity will serve the ESS market, with the remaining 30% going to EVs. The 19 Chinese producers tracked by GGII are investing a combined 180 billion yuan ($26.3 billion) in new lithium-ion factories.

The expansion is being driven by surging demand linked to AI data centre growth and global decarbonisation, with global ESS battery demand already up 79% year-on-year to 550 GWh in 2025, where Chinese firms hold over 80% market share.

CATL alone is investing 20 billion yuan in a single zero-carbon production hub in Fujian capable of delivering up to 200 GWh annually. However, Chinese regulators have begun intervening, convening major battery makers to address concerns about irrational price competition and overcapacity.

“Mainly for energy storage.” Yup. That’s what batteries do.

That was poorly worded of me. I meant to highlight this point:

Around 70% of the new capacity will serve the ESS market, with the remaining 30% going to EVs.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
