Highlights

A tubular solid oxide electrolyser completed a 1,000-hour pilot at BlueScope’s Port Kembla Steelworks.
CSIRO reported electricity use below 36 kilowatt-hours per kilogram of hydrogen during the trial.
ARENA announced AUD 15 million toward a separate AUD 30 million Hadean industrial demonstration.
The funded scale-up remains a future technical test, not an announced commercial BlueScope hydrogen Supply arrangement.

BlueScope Steel Limited manufactures and supplies steel products, including through its Port Kembla Steelworks in New South Wales. The company (ASX:BSL) has hosted a trial of tubular solid oxide electrolysis technology developed by CSIRO and commercialised by Hadean Energy. On 5 November 2026, the Australian Renewable Energy Agency announced funding for a larger Hadean demonstration, giving renewed relevance to the earlier Port Kembla results. The funding concerns the technology developer's next test; it is not confirmation that BlueScope has committed to buy hydrogen from the planned plant or adopt the technology commercially.

Port Kembla Results From the Pilot

The earlier trial at BlueScope's Port Kembla site completed 1,000 hours of operation using steam generated during steelmaking. CSIRO reported electrical input below 36 kilowatt-hours per kilogram of hydrogen, compared with approximately 50 to 55 kilowatt-hours cited for other electrolyser technologies. These figures relate to the specific trial conditions and do not establish commercial production costs. The trial demonstrates technical operation in a working steelworks, including the use of industrial steam as a process input. BlueScope Steel (ASX:BSL) acted as the pilot host, allowing the equipment to be tested in an industrial environment rather than solely under laboratory conditions.

New Funding and the Industrial Demonstration

ARENA announced AUD 15 million toward an approximately AUD 30 million Hadean project in November 2026. Official project information describes a proposed 200–300 kilowatt demonstration, intended to move technology readiness from level six toward level nine. The phases include detailed engineering, Manufacturing development, procurement, safety assessments and site integration, followed by construction, commissioning and operation. BlueScope Steel (ASX:BSL) is connected through the completed Port Kembla pilot, but the announced demonstration is a separate undertaking. ARENA indicated that the planned industrial unit is expected to be developed in Victoria, subject to final arrangements and approvals.

Why the Tubular Design Matters

Conventional electrolysers use electricity to separate water into hydrogen and oxygen. Solid oxide systems operate at higher temperatures and can use steam or other process heat, reducing the amount of electrical energy needed for electrolysis. Hadean's tubular configuration is intended to support durability and manufacturing efficiency. The design can also process steam and carbon dioxide together to produce synthesis gas for potential chemical and fuel applications. These possibilities are not established commercial Revenue streams at BlueScope Steel (ASX:BSL). The company’s trial shows one potential industrial integration pathway; broader adoption would require performance, safety and economic assessment at significantly greater operating scale.

What Must Be Proven Before Deployment

The next demonstration is intended to establish whether the system can maintain performance and reliability at higher capacity. Engineering an installation around an existing industrial site's heat and steam flows creates practical constraints that a smaller pilot may not fully reveal. Hadean has also indicated further Capital will be needed for construction-related activity. For BlueScope Steel (ASX:BSL), lower-emissions steelmaking depends on several technologies, commercial conditions and changes to industrial processes. This specific trial should not be presented as evidence of a completed decarbonisation programme. Its relevance is that industrial waste heat could reduce an input cost of hydrogen if the technology remains efficient and durable at scale.

Key Insights

BlueScope Steel (ASX:BSL) provided an industrial setting for a successful pilot whose results now support a funded larger demonstration by Hadean. The technical evidence is encouraging but remains distinct from a binding commercial deployment. Further engineering, commissioning, sustained operation and economic validation are needed before any broader steelmaking application can be assessed.
