'Green steel': Swedish company ships first batch made without using coal:
The world's first customer delivery of "green steel" produced without using coal is taking place in Sweden, according to its manufacturer.
The Swedish venture Hybrit said it was delivering the steel to truck-maker Volvo AB as a trial run before full commercial production in 2026. Volvo has said it will start production in 2021 of prototype vehicles and components from the green steel.
Steel production using coal accounts for around 8% of global greenhouse gas emissions. Hybrit started test operations at its pilot plant for green free steel in Lulea, northern Sweden, a year ago. It aims to replace coking coal, traditionally needed for ore-based steel making, with renewable electricity and hydrogen. Hydrogen is a key part of the EU's plan to reach net zero greenhouse gas emissions by 2050.

The most energy-intensive role of the carbon is (3) the reduction of iron oxides in the ore to iron.
Do the reduction with carbon and you get CO2 (and iron)
Do it with hydrogen and you get H2O leaving.

thank you. I never bothered that much with chemistry because there were too many details to remember. now and then the stupidity shows...
