"The green steel transition won’t happen overnight and significant challenges remain.

Cheap, large-scale green hydrogen and renewable electricity will be required. And even if green hydrogen is used, to achieve net-zero emissions the blast furnace method will still require carbon-capture and storage technologies – and so too will DRI, for the time being.

Private sector investment is needed to create a global-scale export industry. Australian governments also have a big role to play, in building skills and capability, helping workers retrain, funding research and coordinating land-use planning."

Charley, to paraphrase the article's conclusion: "Green steel makes no financial sense whatsoever. It relies on carbon-capture and storage technologies which have never borne fruit. But if we pretend it holds great potential to reduce carbon emissions, maybe we can get investors to buy in anyway, and Australia can make a lot of money. If we play our cards right, Australia can be a major player in 'the green manufacturing revolution'."

Would you say that's an accurate assessment?

Australia’s abundant and cheap wind and solar resources mean we’re well placed to produce the hydrogen a green steel industry needs.

I wonder-- could this somehow be built into a renewable overbuild scenario-- where rather than curtailment, that surplus energy is used for such steel production processes?

It would require a steel manufacturer who was willing/able to close his plant, and a work force willing/able to forego making steel for pizza delivery, whenever the weather didn't cooperate. So in a word: no.
