Iron can be produced without coal, because hydrogen can be used for reduction of the iron oxide.

The IP is tightly held by a handful of European steelmakers who aren't interested in transferring it abroad as it would remove their CBAM advantage against Asian exporters and completely destroy them and Germany (ThyssenKrupp), Sweden (LKAB, HYBRIT), and Austria (Voestalpine) would lose their temporary competitive advantage.

And all the Asian countries I listed (excluding Australia - who is Asia's Chile) are planning on dramatically expanding domestic steel production over the next decade to help with their infrastructure buildouts, so are primarily using domestic non-alloy steel and cement.

The Asian steelmakers will eventually figure and scale it out, but that will take an additional decade because they also won't transfer IP to their competitors. By that point it will be the late 2030s and in some cases the 2040s.

Intellectual property in making green steel is not the big competitive advantage of European steelmakers. Green steel making is not ultra high-tech product like the ASML photolithography machines. If it would be a big competitive advantage then Thyssenkrupp would not need €2 billion German government state aid for its new green steel plant in Duisburg.

"Most of Asia's steelmaking capacity is blast furnace-based, accounting for around 90% of output in China, 73% of output in Japan, 69% in South Korea and 46% in India, according to World Steel. With many of the region's blast furnaces at an early stage in their life cycles, it is unlikely that they would be phased out soon, and so many of the decarbonization efforts are based on the continued use of this production route."

"Overall, the path to decarbonization in the Asian steel sector is fraught with challenges, requiring significant investment and regulatory support to ensure the transition to sustainable practices is both feasible and economically viable."

So steelmakers in Asia are concentrating on low production costs, steelmakers in Europe are concentrating on low carbon emissions.

It is for ThyssenKrupp (Germany), LKAB (Sweden), HYBRIT (Sweden), and Voestalpine (Austria). Chinese, India, Vietnamese, Saudi, and other steelmakers cannot export their steel and steel products competitively to Europe and their European operations were about to get hit by CBAM related violations (until the EU backed down on carbon emissions regulations a couple weeks ago), which made the EU-27 a captive market for those 4.

Only German, Swedish, and Austrian steelmakers can. Dutch, French, Luxembourgish, and Italian steelmakers (who are all now owned by Asian steelmakers) cannot.

And this is why nothing will happen with regards to climate change - sovereign corporate interests will always trump global interests.
