1. What Is the Carbon Capture in Steel Market?
The Carbon Capture in Steel Market comprises technology systems, engineering services, and equipment that integrate CO2 capture into blast furnace, direct reduction, and electric arc steelmaking routes to reduce iron and steel production emissions. The market includes post-combustion amine absorbers for blast furnace gas treatment, chemical looping combustion systems, oxy-fuel configurations, and engineering and commissioning services for integrated steel plant retrofits. These systems serve integrated steel mills, mini-mill operators, and specialty steel producers pursuing emissions reduction aligned with industrial decarbonization policy and carbon pricing. The scope excludes fully hydrogen-based direct reduction steelmaking that eliminates CO2 at the process source, and carbon capture applied to upstream coking and coal preparation that serves different emission boundaries.

3. Emerging Technologies
- Chemical looping combustion systems are advancing for steelmaking applications to combust blast furnace gas with metal oxide oxygen carriers, generating a concentrated CO2 stream without nitrogen dilution. Growing adoption in pilot steel facilities is improving capture efficiency and reducing separation cost compared with post-combustion treatment of mixed flue gas.
- Gas fermentation systems that convert captured CO2 and CO from steelmaking off-gas into chemicals and fuels are emerging as integrated emissions and value-recovery approaches. Increasing deployment at integrated steel mills is improving economic viability by generating revenue from CO2-derived products alongside emissions reduction.
- Blue hydrogen integration with direct reduction iron systems is advancing to replace natural gas in DRI and reduce CO2 intensity through partial hydrogen substitution with CCS on remaining emissions. Continued innovation in hydrogen-DRI-CCS configurations is developing pathways to near-zero steelmaking in regions with access to affordable hydrogen.
- Digital CO2 intensity tracking platforms are advancing to monitor blast furnace and EAF emissions in real time and generate certified carbon data for low-carbon steel product reporting. Expanding integration with steel supply chain auditing is improving emissions transparency and enabling differential pricing for CCS-backed low-carbon steel products.
Such innovations are driving change across adjacent industries too. Discover more in our Direct AIr Capture Carbon Market.
4. Key Market Opportunity
One of the major opportunities in the Carbon Capture in Steel Market is the deployment of concentrated CO2 stream capture at smelting reduction and top-gas-recycling blast furnaces where enriched off-gas reduces capture cost compared with conventional dilute flue gas treatment. Integrated steel mills using conventional blast furnaces face high per-tonne amine capture costs owing to nitrogen-diluted flue gas, creating a gap for lower-cost approaches that process concentrated CO2. Advances in HIsarna smelting, chemical looping combustion, and top gas recycling are generating higher-purity gas streams that improve capture economics and lower the breakeven carbon price for steel CCS. Steel producers developing CCS-backed low-carbon steel supply stand to command green steel price premiums from automotive, construction, and manufacturing customers with emissions reduction obligations.

7. Key Market Trends (2026–2034)
Three major forces are shaping the Carbon Capture in Steel Market trajectory over the forecast period:
Industrial Decarbonization Policy Is Compelling Blast Furnace Operators to Pilot Post-Combustion Capture.Integrated steel mills operating under EU ETS and national carbon pricing are advancing CCS pilot programs at blast furnace facilities as unabated steelmaking faces rising regulatory cost. Thyssenkrupp advanced its nucarbons CCS project at its Duisburg steel complex in 2024, targeting post-combustion capture of blast furnace top gas as a pathway toward low-carbon steel.
Top Gas Recycling Combined with CCS Is Being Developed to Improve Carbon Efficiency at Blast Furnaces.Steel producers are evaluating blast furnace top gas recycling paired with CCS to reduce coke consumption and capture CO2-enriched off-gas more efficiently than treating conventional dilute flue gas. ArcelorMittal advanced its Carbalyst fermentation project at the Ghent steelworks in 2024, using LanzaTech gas fermentation to convert CO2-rich blast furnace gas into ethanol while reducing net emissions.
HIsarna Smelting Reduction Technology Is Generating Concentrated CO2 Streams for Lower-Cost Capture.Steel developers are advancing smelting reduction processes that produce concentrated CO2-rich off-gas directly suited for CCS without extensive pre-treatment or gas separation. Tata Steel Netherlands progressed its HIsarna smelting reduction pilot at IJmuiden in 2024, generating a high-purity CO2 stream from iron ore reduction with an intrinsic cost advantage for capture.

8. Segmental Analysis
By Steelmaking Route, the blast furnace and BOF with CCS segment dominated the Carbon Capture in Steel Market in 2025, driven by the volume of operating blast furnace capacity requiring near-term decarbonization pathways. Integrated steel producers continue advancing blast furnace CCS owing to the scale of existing assets and the timeline challenge of transitioning fully to DRI-EAF within regulated compliance periods. The direct reduction and EAF with CCS segment is the fastest-growing Steelmaking Route category, driven by expanding gas-based DRI capacity that generates a carbon stream suited for capture. Developers are advancing DRI-CCS configurations as natural gas and hydrogen DRI facilities expand in regions with available CO2 transport and storage infrastructure.
By Capture Technology, the post-combustion amine scrubbing segment dominated the Carbon Capture in Steel Market in 2025, reflecting its adaptability to existing blast furnace top gas export streams and industrial track record. Steel operators continue selecting amine scrubbing owing to available engineering expertise and commercial deployment experience across analogous industrial flue gas capture applications. Chemical looping combustion is the fastest-growing Capture Technology category, driven by the potential to generate high-purity CO2 without nitrogen dilution and reduce total capture energy requirements. Developers are advancing chemical looping systems as the concentrated CO2 stream advantage improves steel CCS economics relative to dilute flue gas post-combustion routes.
