Journey to a green future

Steel, re-forged for a hydrogen century.

For more than half a century, POSCO has made the steel that builds nations. Now we are rebuilding how steel itself is made — replacing coal with hydrogen, and intuition with intelligence.

Who we are

We were founded in 1968 to give a nation the steel it needed to rise. The next chapter asks something harder: to make that same strength without the carbon. We are turning fire into hydrogen, mills into intelligent systems, and a steelmaker into a materials company for the century ahead.

HyREX · Hydrogen Reduction

Same iron. Water instead of CO₂.

HyREX replaces coal with hydrogen to turn iron ore into iron. It is the technology at the heart of POSCO's plan to make carbon-neutral steel by 2050.

Intelligent Works

A steelworks that thinks.

01

AI process control

Machine learning models tune furnace and rolling conditions in real time, holding quality to tighter tolerances than any manual process.

02

Digital twins

Every line has a virtual counterpart, letting engineers test changes, predict wear and plan maintenance before a single bolt is turned.

03

Predictive quality

Vision systems and sensors catch defects as they form, so customers receive steel that meets spec the first time.

04

Energy intelligence

Smart energy management balances power across the works — the groundwork for a hydrogen-and-electricity future.
