Three main approaches are known to produce steel
• Well established worldwide process
• Almost all steel plants use C as a reducing agent
• Process is close to thermodynamic optimum
• First demo plants show feasibility
• Process needs new installation of assets
• H2 must be produced without CO2-footprint
• If CO2 free energy is used
thyssenkruppp AG 4 |Conference on hydrogen 2018 October 22th 2018 Dr. Markus Oles
The high energy demand is the reason for the origin of CO2 in the atmosphere
A Steel Plant needs
approximately as much … as the city of
Energy… Berlin.

Steel production is coming with huge amounts of top gas
2 Mio. Nm3 top gas per hour
Daily amount of top gas:
~300.000 m³ Gas
CO2 21%
CO 25%
N2 43%
Ar < 0.1%
CH4 2%
H2 8%
Other < 0.1% Steel mill Blast furnace Coke oven
