Companies like SSAB have developed plans to eliminate coal from their steel plants. In place of coke, derived from coal, the company plans to use clean hydrogen. Like carbon, hydrogen can also strip oxygen from iron ore to make the pure iron needed in steelmaking. But in this reaction, the resulting "emission" is H20.

Why do we use coal to make steel? We know that we need to reduce our carbon emissions by 80 or 90% if we want to avoid the worst effects of climate change, so it's clear that we can't keep burning coal to make steel. What can we do instead? The good news is that coal is not our only option.

Coking plant. Coke's role in steelmaking is to provide the heat needed to melt the ore, whose natural state is iron oxide, the rust you see on iron after it has been exposed to the atmosphere. Coke also 'steals' the oxygen from the iron ore, so that it can become iron. In the coking plant, coal is heated to 1250c in the absence of oxygen ...
