The Australian Renewable Energy Agency (ARENA) committed AUD 19.8 million to the NeoSmelt joint venture to fund a front-end engineering design (FEED) study for a direct reduced iron-electric smelting furnace (DRI-ESF) pilot plant at Kwinana, Western Australia, aimed at proving Pilbara iron ore can be converted into lower-carbon iron without a coking-coal blast furnace. The consortium, founded by BlueScope, BHP and Rio Tinto, welcomed Woodside Energy and Mitsui Iron Ore Development as new equal-equity participants alongside the grant announcement. Total project cost is AUD 48.85 million, with the study running from May 2025 to August 2026 ahead of a targeted final investment decision.

Analyst notesShow

Mechanism

DRI-ESF (direct reduced iron - electric smelting furnace) is a two-stage decarbonisation pathway distinct from Calix's ZESTY flash calciner route already in the register (2025-07-24-australia-arena-calix-zesty-green-iron-grant): ore is first reduced to solid direct reduced iron, then melted in an electric smelting furnace, avoiding the coking-coal blast furnace step. The AUD 19.8M ARENA grant funds only the FEED study (total project cost AUD 48.85M) — not construction of the pilot plant itself, which depends on a final investment decision targeted for 2026 and prospective 2028 start of operations. Severity is set at 2/5, consistent with other single-project ARENA demonstration/FEED grants in the register: a strategically framed decarbonisation subsidy, but pre-commitment capital rather than a production-scale subsidy.

Downstream implications

A second major-miner-backed green-iron pathway (alongside ZESTY) now

competing for eventual commercial-scale Australian government and state co-funding, both targeting conversion of Pilbara hematite ore into higher-value low-carbon iron products rather than raw ore exports.

BHP, Rio Tinto and Woodside taking equal equity stakes alongside

BlueScope signals major upstream miners hedging against a scenario where importers (especially the EU via CBAM) increasingly discount or restrict high-emissions steel inputs.

Kwinana, WA becomes a second location (after any ZESTY site) to

watch for green-iron pilot infrastructure; a positive FID here would be a reference case for hematite-based DRI-ESF at commercial scale.

Open questions

Whether Western Australia state government co-funding accompanies

the federal ARENA grant, as it has for prior green-iron/hydrogen projects.

Outcome of the FEED study and timing of the final investment

decision for the Kwinana pilot plant.

Whether NeoSmelt and ZESTY are ultimately complementary or

competing pathways for Australia's iron-ore decarbonisation policy push.
