This is mind blowing - as if it works as advertised - it could mean mostly green steel arrives years earlier than the hydrogen method. That is, a large CO2 reduction decades earlier is better than none. Indeed - if this works as advertised and is a 90% reduction - do we even need to get rid of the last 10% of steel emissions as it's 10% of steel's 8% global emissions. OR 0.8% of total emissions. If the economics of hydrogen reduction just don't work out compared to this - I'm happy to settle with this and throw some more iron filings in the ocean (or whatever other carbon sequestration scheme you're into) to offset the carbon.
