> You need A LOT of electricity to have coal free steel production.

Yes. And?

All that matters here is the cost. Is the cost of the energy (+equipment wear etc.) needed per ton of coal-free steel higher or lower than the cost per ton of whatever the current best coal-based method is?

That's not constant by time or place, so I can easily believe that the Scandinavian Peninsula does this with a bunch of cheap hydro, that Iceland does it with a bunch of cheap geothermal, that Denmark and Germany lose whatever steel industry they might have, that the UK does with cheap wind, that Spain does it with cheap sun, that France does it with state-subsidised "cheap" nuclear.

> Its not green but typical greenwashing - you don't emit CO2, but you import energy made from coal etc.

Or nuclear, or renewables.
