Comparison of conventional fossil fuel-based steelmaking process versus the new approach from HYBRIT
PolymPart: Volvo Group has revealed the world’s first vehicle made of fossil-free steel from SSAB – made in Volvo Construction Equipment’s facility in Sweden. It is announced by Volvo company that more vehicles will follow in 2022 in what will be a series of concept vehicles and components using fossil-free steel from SSAB.
Now, this question may arise that how fossil-free steel is made?
To make conventional steel, iron ore is converted into iron by removing oxygen. One can remove oxygen using coal and coke following the blast furnace process. To make fossil-free steel, hydrogen gas using the HYBRIT process is used along with fossil-free electricity
A move toward green steel is an important step for the transport and infrastructure industries as a whole, particularly considering that around 70% of a truck’s weight comes from steel and cast iron, with the figure for Volvo machines even higher. This first concept machine, produced at Volvo CE’s facility in sweden, is just the start, with smaller-scale series production planned by 2022, and mass production set to follow.
