POSCO to demo hydrogen-reduction steel at 300,000-ton scale by 2028

POSCO Group plans a large-scale demonstration of hydrogen-reduction ironmaking, aiming to produce 300,000 tons of steel annually by 2028 in Pohang, South Korea. The effort is framed as the first step in building an industrial ecosystem linking clean energy, technology, markets, and policy to support low-carbon steel production.

What POSCO is planning and why it matters

POSCO intends to build a demonstration facility in Pohang with an annual capacity of 300,000 tons, dedicated to hydrogen-reduction ironmaking. This process uses hydrogen instead of coal to produce iron, potentially lowering carbon emissions associated with steelmaking. The project is described as part of a broader effort calledSteel GX, within Korea’s Green Transformation strategy. The company says the project will verify the technology and then expand to other sites, including Gwangyang, forming an eco-system that connects clean energy supply, technology, markets, and policy.

Who could be affected by the plan

The move is positioned as a national and industrial initiative rather than a single company effort. Potentially affected groups include workers at steelmaking facilities and suppliers in the clean-energy and hydrogen sectors, regional communities around Pohang and Gwangyang, and policymakers overseeing energy and industrial policy. The plan emphasizes a stable supply of clean energy to support continuous operation (24 hours a day) in hydrogen-based steelmaking.

Practical next steps and what to watch

Watch for official project milestones from POSCO and partners, such as concrete construction timelines, energy-supply commitments, and demonstration metrics (output, emissions, energy use). If the project proceeds, expect details on hydrogen sourcing, cost considerations, and how this demonstration connects to broader industrial policies and climate targets. Local readers should monitor regional updates for any traffic, construction, or employment impacts near Pohang and Gwangyang.

Unanswered questions and limits

Key uncertainties include the availability and cost of clean hydrogen at scale, the actual emissions reductions achieved versus conventional steelmaking, and when commercial-scale deployment will begin beyond demonstrations. The source indicates a focus on an ecosystem approach but does not provide specifics on policy incentives, timelines beyond 2028, or potential market structures for low-carbon steel.
