December 2025.
The scoreboard is frozen, but the game is over.
China will produce 68–74 % of global non-lithium battery capacity by 2029.
Not because they are smarter.
Because they started building in 2023 and the West is still holding stakeholder consultations.
Here is the factory list that ends the debate.
Every single one is either already pouring concrete or has final investment decision signed.
| Company | Chemistry | Location | Annual capacity by 2029 | First full production | Cost target 2029 |
|---|---|---|---|---|---|
| CATL | Sodium-ion | Ningde + Guizhou | 1,100 GWh | Q3 2027 | $14/kWh |
| BYD | Sodium + LFP | Multiple (8 sites) | 900 GWh | Q1 2028 | $16/kWh |
| HiNa Battery | Sodium-ion | Beijing + Inner Mongolia | 420 GWh | Q4 2026 | $12/kWh |
| REPT (Tsingshan) | Sodium-ion | Wenzhou + Indonesia | 380 GWh | Q2 2027 | $13/kWh |
| Great Power | Iron-air pilot | Guangdong | 250 GWh (100-hr) | 2028 | $4/kWh |
| Zhongbi New Energy | Iron-air | Hebei | 300 GWh | 2029 | $3.5/kWh |
Total Chinese-controlled capacity by end-2029: ≈3,350 GWh/year
That is more than the entire global lithium-ion production of 2024.
Now the rest of the world:
| Company / Country | Chemistry | 2029 capacity (GWh) | Notes |
|---|---|---|---|
| Form Energy (USA) | Iron-air | 42 | Fully booked until 2031 |
| Northvolt (Sweden | Sodium (license) | 60 | Still looking for €2 B |
| Redwood/QS licensees | Structural/ambient | ~120 combined | Mostly pilot, no megafactory yet |
| India (multiple) | Sodium-ion | 80 | Reliance + Tata, 2028–2030 |
| Everyone else | — | <100 total | — |
Total non-China by 2029: ≈400–450 GWh/year
China wins 8:1 on volume, 12:1 on the ultra-long-duration chemistries that actually kill the grid.
How they did it – the boring playbook that always works
- 2023–2024: Beijing adds sodium-ion and iron-air to the “35 critical technologies” list → zero-interest 15-year loans from policy banks
- 2024: Local governments in Inner Mongolia and Guizhou offer free land + 15-year tax holiday if you build >200 GWh/year
- 2025: CATL simply copies its lithium playbook – announce absurd capacity, raise $8 B in one week, start digging before permits are final
- 2026–2028: Entire supply chain (sodium carbonate, Prussian blue cathode, iron oxide slurry) is brought in-house at negative margins to starve foreign competitors of precursors
Western response timeline:
- 2024: EU publishes 84-page “Critical Raw Materials Act”
- 2025: U.S. DOE releases $700 M in grants (enough for one 15 GWh factory)
- 2026: California holds 18-month environmental review for a sodium plant
- 2027: Germany finally approves Northvolt expansion after labor unions negotiate co-determination seats
- 2028: Texas passes “right to mine” laws the same month CATL’s 1 TWh line comes online
The commodity choke points that don’t exist
Lithium had cobalt, graphite, and Chile.
Sodium has table salt and steel rust.
- China produces 79 % of global refined sodium carbonate today (used in glass and detergents). They simply divert 4 % of output.
- Iron oxide waste: China generates 1.2 billion tons per year from steel mills. They need 0.08 % of it for 3 TWh of iron-air.
- Aluminum for current collectors: 62 % Chinese smelting capacity and rising.
There is no “friend-shoring” possible when your friend doesn’t have the raw molecules.
The bloodbath pricing schedule nobody in the West wants to model
- 2027: Chinese sodium-ion packs hit $25/kWh in domestic EV tenders
- 2028: Export price drops to $18/kWh to kill Korean LFP players
- 2029: Iron-air long-duration leaves factory at $3.80/kWh and is installed under highways for $8/kWh turnkey
- 2030: CATL offers “all-you-can-store” contracts to utilities: $800 per kW one-time fee, 100-year warranty, zero energy forever
At that point the only question for a U.S. or European utility executive is how quickly they can surrender.
The geopolitical tell that happened last week
December 4, 2025: Saudi Arabia quietly cancels the remaining $300 billion of oil-city projects and signs a memorandum with CATL + BYD for 1.8 TWh of iron-air storage under the desert by 2033.
The money quote from the leaked PIF memo:
“Peak oil demand has been moved forward from 2040 to 2029. We intend to sell the last barrel at the highest possible price and then never need another.”
What the victory looks like on the ground
By 2031 every new apartment building in Shanghai, Jakarta, and São Paulo will have its foundation poured with iron-air cells instead of rebar.
The building is the battery.
The battery is the building.
The residents will never see an electric bill exactly once in their lives: a $400 line item at closing labeled “lifetime energy surcharge.”
California will still be holding community listening sessions about whether iron-air slurry constitutes a “chemical storage facility” under Proposition 65.
China will not wait.

The factory lights are already on.
They just haven’t turned on the Western ones yet.
