Indonesia's nickel policy was, until very recently, judged on its costs more than its benefits. The ore export ban of 2020 destroyed a sizeable upstream business, the high-pressure acid leach (HPAL) projects ran into early execution problems, and ESG criticism of smelter emissions and tailings was loud. In the past eighteen months the calculus has shifted. Several HPAL units are running at design capacity, mixed-hydroxide precipitate (MHP) is leaving Sulawesi in volume, and the first integrated nickel-to-cathode lines are operating commercially. The downstream bet is finally producing what Jakarta said it would.
Key takeaways
- HPAL execution issues from 2022–2023 are now largely resolved at scale.
- Integrated nickel-to-cathode chains are producing battery-grade material at globally competitive cost.
- Ownership of the value chain runs primarily through Chinese partnerships — a strategic question for offtake.
- Cobalt by-product capture is changing global cobalt market structure.
Why this round of HPAL worked
Earlier HPAL programs ran into autoclave reliability, tailings management and acid balance problems. The current generation benefited from Chinese engineering iteration learned from Ramu and Goro, autoclave designs sized down to manageable units, and tighter integration with ore sources at single sites. The first units in Morowali and Weda Bay are now operating at high availability.
- Engineering. Smaller modular autoclaves easier to commission and maintain.
- Integration. Co-located ore sources reduce slurry transport problems.
- Operator experience. Years of trial-and-error are now production know-how.
What it does to battery costs
Indonesian MHP and cathode precursor is meaningfully cheaper than Western alternatives at comparable specifications. The result is a structural cost advantage for cell makers using Indonesian feedstock, particularly for nickel-rich cathode chemistries.
Why Western processors lose competitiveness
European and North American refining ambitions face higher capital cost, more expensive power and slower permits — they cannot match Indonesian landed cost without subsidy.
Cobalt as the by-product
Cobalt extraction during HPAL is meaningful. Indonesian cobalt has effectively re-leveraged a market the DRC dominated.
Capacity online
Battery-grade output is rising fast.
| Year | MHP output (kt Ni) | Cathode precursor (kt) |
|---|---|---|
| 2023 | ~250 | ~80 |
| 2025 | ~620 | ~210 |
| 2027e | ~950 | ~380 |
Jakarta's bet looked questionable at the start; it does not look questionable now.
Frequently asked questions
Is the ESG profile improved?
Marginally — emissions intensity is falling, but coal-fired captive power remains the dominant input.
Who controls the chain?
Predominantly Chinese capital and technology, with Indonesian state participation.
Does this end the case for Western refining?
For unsubsidized projects, largely yes. Strategic subsidy is the only path forward.
The bottom line
Indonesia's downstream nickel policy now looks like a successful industrial play. The cost geography of EV batteries has shifted to Sulawesi, with significant consequences for Western refining ambition and for the cobalt market.
