Australia is taking a major step toward heavy industry decarbonization with the launch of the Mid-West Green Iron project in Western Australia. Led by Progressive Green Solutions (PGS), the initiative will rely on German technology leader thyssenkrupp Nucera to supply a 1.4 GW electrolyzer system, making it one of the largest hydrogen-based steel projects in the world to date.
Large-Scale Steelmaking Transformation
Once operational, the project will produce 7 million metric tons of green direct reduced iron (DRI) pellets annually, with approximately 2.5 million metric tons processed into hot briquetted iron (HBI)—a high-value, export-ready product used in low-carbon steelmaking. By replacing coal with hydrogen in the reduction process, the facility is expected to cut carbon dioxide emissions by up to 90% compared to traditional blast furnaces.
Looking ahead, PGS has set ambitious expansion targets: 30 million metric tons of DRI and 10 million metric tons of HBI per year. At that scale, the Mid-West project would rank among the largest green steel initiatives in the global market.
The Technology Backbone
At the heart of the project is thyssenkrupp Nucera's scalum® alkaline electrolyzer system, with individual units rated at 20 MW. These modular systems can be scaled up to meet future production growth. The electrolyzers will generate hydrogen using only renewable energy, enabling a fully sustainable production chain.
Both companies are working toward an engineering, procurement, and fabrication (EPF) agreement to finalize supply terms. However, thyssenkrupp Nucera has indicated that the project is unlikely to have a material financial impact before fiscal year 2026–2027.
Timeline and Milestones
The Mid-West Green Iron project is still in the planning and investment decision phase. If the final investment decision (FID) is approved, first exports are expected by 2029. This timeline reflects both the complexity of large-scale hydrogen projects and the challenges of developing export infrastructure in remote Australia.
Challenges Ahead
Despite the promising outlook, this pioneering project faces economic and competitive hurdles. Mining giant BHP recently warned that building a large-scale green steel industry in Australia could be more costly than in competing countries, raising concerns about long-term competitiveness. High labor and energy costs, along with infrastructure constraints, will test the project's commercial viability.
Toward Net Zero
Still, the stakes are high. Steel production accounts for 7–9% of global carbon dioxide emissions, making it one of the hardest sectors to decarbonize. A successful outcome in Western Australia could serve as a blueprint for other nations seeking to combine renewable energy, hydrogen, and local resources to produce low-carbon industrial materials at scale.
If delivered on schedule, the Mid-West Green Iron project could not only solidify Australia's role in the global energy transition but also set a precedent for hydrogen-powered heavy industry worldwide.
