BeijingChina makes more than half the world’s steel.
China’s 15th Five-Year Plan named hydrogen an industry of the future; 3 ministries now reward city clusters that meet hydrogen-for-steel targets.
Officials call this an inflection point; only a handful of commercial-scale hydrogen steelmakers operate globally, including in China.

WHY STEEL IS HARD TO DECARBONIZE
Steel is roughly 7-9% of global CO2 emissions. The problem is chemistry, not energy: blast furnaces use coke (carbon) to strip oxygen from iron ore. The carbon doesn't just heat the reaction — it IS the reaction. Switching the heat source to renewables doesn't help; you have to replace the reductant.
THE CHINA SCALE PROBLEM
China produces over a billion tonnes of steel a year — more than the rest of the world combined. Even a small percentage shift toward hydrogen-based production represents more capacity than every other green-steel project on Earth put together.
GREEN VS GREY VS BLUE
Hydrogen is colorless; the labels describe how it's made. Grey hydrogen splits natural gas (releases CO2). Blue is grey plus carbon capture. Green uses electrolysis powered by renewables. Today over 95% of global hydrogen is grey — making 'hydrogen steel' meaningless unless the hydrogen itself is clean.
THE ELECTRICITY MULTIPLIER
Producing one tonne of green steel takes roughly 50-60 kg of hydrogen, which takes about 2.5-3 MWh of electricity to electrolyze. Replacing China's blast furnace fleet with hydrogen DRI would require electricity on the order of all of India's annual generation — solely for the hydrogen.
THE FIVE-YEAR PLAN MECHANISM
China's Five-Year Plans are not Soviet-style production targets. They identify 'industries of the future' and direct provincial governments, state banks, and city clusters to compete for designation as pilot zones. The actual capital and execution are local; the plan sets the score sheet.
THE COMMERCIAL FRONTIER
Sweden's HYBRIT delivered the first fossil-free steel to Volvo in 2021. H2 Green Steel (Stegra) is building a 5-million-tonne plant in Boden. China's Hebei Iron & Steel commissioned a hydrogen-DRI demonstration in 2023. The total global capacity is still under 10 million tonnes — less than 1% of Chinese output.
