How could POSCO's Gwangyang complex expansion affect Hyundai?

Likely What happens if… A possibility worth considering, not a forecast.

Hyundai may benefit from POSCO's expanded battery material supply The expansion of POSCO's Gwangyang complex strengthens the domestic supply chain for critical battery materials, which is vital for Hyundai's operations. Specifically, the cathode material plant at the Yulchon Industrial Complex has an annual production capacity of 90,000 tons, sufficient to supply batteries for approximately 850,000 Hyundai Ioniq 5 electric vehicles. Furthermore, POSCO's lithium hydroxide plant, which uses Australian ore, has a capacity of 43,000 tons, helping to diversify the supply chain and reduce reliance on overseas suppliers.

  • Posco-Pilbara Lithium Solution has an annual production capacity of 43,000 tons of lithium hydroxide using Australian ore.koreaherald.com
  • The Gwangyang LNG Terminal expansion was a 949.2 billion won project, adding two 200,000-kiloliter tanks.koreaherald.com

Why it matters

For Hyundai, a major conglomerate and automotive player, securing a stable and diversified supply of critical battery materials is essential for maintaining production and meeting global EV demand. The expansion of POSCO's facilities directly addresses supply chain vulnerabilities, allowing Hyundai to rely more heavily on domestic, high-performance materials.

This development is part of a wider trend in South Korea to build a comprehensive industrial ecosystem. By linking LNG infrastructure, advanced battery manufacturing, and metal recycling, POSCO is strengthening the nation's position in critical global supply chains amid geopolitical tensions and supply disruptions.

What we don't know yet

  • How will the increased domestic capacity affect the pricing of cathode and lithium materials?
  • What is the timeline for POSCO to utilize its reserved space for four additional LNG tanks?

What would change this answer

Global EV demand accelerates significantlyThe demand for POSCO's materials will increase, potentially leading to stronger long-term contracts and greater material security for Hyundai.
Geopolitical tensions disrupt Australian lithium importsThe importance of POSCO's domestic processing and recycling capabilities will increase, further stabilizing the supply chain for Hyundai.
