POSCO joins K-GX to build hydrogen steelmaking cluster and low-carbon steel market in Korea

POSCO Group has joined South Korea's K-GX green transition strategy with a plan to replace coal with hydrogen in steelmaking. The centerpiece is HyREX, a hydrogen reduction process that uses iron ore fines directly and runs continuously. POSCO plans to build a 300,000 ton per year demonstration facility at Pohang by 2028, linked to clean hydrogen supply from the Pohang and Ulsan industrial complexes. The company estimates the cluster will cut emissions by 560,000 tons per year and create 14,000 jobs in the southeast region. POSCO also wants a green premium market for low-carbon steel, backed by standards and a green purchasing law, so that low-carbon steel has real demand. After Pohang, the plan is to expand the model to Gwangyang in the southwest. The key constraint is clean energy supply. Hydrogen steelmaking needs large, stable, economical power and hydrogen around the clock, so delivery will depend on how fast that infrastructure actually gets built.

Good to see steel decarbonization getting a concrete timeline. The 300k ton HyREX demo at Pohang by 2028 is the detail that matters. Hydrogen steelmaking only helps if the hydrogen is actually clean and cheap, so the supply side is the part to watch.

They say clean energy supply is critical because the process runs 24/7. That means firm power and hydrogen, not just occasional surplus renewables. I want to know where the electrolyzers get their electricity and what price they are assuming before calling the economics real.

The green premium market is the piece most steel decarbonization plans skip. Standardizing low-carbon steel and a green purchasing act could create actual demand. Without that, producers eat the cost and the demonstration stays a demo. Worth tracking whether the policy follows the announcement.

Hydrogen direct reduction replaces coal as the reducing agent, but it also needs large amounts of clean power for electrolysis and continuous operation. The 560k tons of annual CO2 reduction sounds solid, yet the real test is matching that with stable hydrogen supply around Pohang and Ulsan.
