Hydrogen for a low CO2 steel production
As the steel industry is responsible for around 6 % of the global anthropogenic CO2 emissions, it has a high potential for mitigating climate change. Hydrogen plays a decisive role for the transformation to a climate neutral steel making. As an alternative reducing agent, hydrogen can partially replace the use of carbon and thereby reduce the CO2 emissions.
In order to establish hydrogen, we are working on its supply:
- CO2-free hydrogen production by methane pyrolysis and
- Separation from H2-rich gases by membrane process,
as well as on the technologies to use hydrogen in the steel industry:
- Partial replacement of injected coal by hydrogen at the blast furnace
- Direct reduction with H2-rich gases up to pure hydrogen.
The following figure shows the research topics of the BFI regarding hydrogen for a low CO2 steel production.
In scope of the following running or planned projects we are working on the implementation of hydrogen in the steel industry:
- H2BF: CO2-Mitigation through injection of H2 into the blast furnace
- Reallabor H2Stahl: Hydrogen technologies for a stepwise decarbonisation of the steel industry (H2 blast furnace and direct reduction with H2)
- Me2H2: Methane pyrolysis for the production of hydrogen and solid carbon
- SCI4climate.NRW: Scientific competence centre for a climate neutral and competitive basic industry in NRW
- LowCarbonFuture: Exploitation of projects for low-carbon future steel industry
- GreenSteel: Green Steel for Europe
Our engagement in initiative and working groups:
- NRW: Initiative from politics, science and industry for a climate-neutral industry in NRW (participation in the hydrogen working group, publication of the discussion paper hydrogen)
- Participation in the focus group “Low Carbon & Energy Efficiency” of the European Steel Platform (ESTEP)
- Participation in A.SPIRE, a European association, which works for the management and implementation of the SPIRE Public Private Partnership
