Decarbonising Iron and Steel Production

Iron and steel production accounts for 2% of UK greenhouse gas emissions*, and traditional steelmaking comes at a cost: for every ton of steel produced through the traditional blast furnace/basic oxygen furnace route, nearly two tons of carbon dioxide are emitted into the atmosphere.

Our expertise in low carbon hydrogen production and distribution, as well as technologies like oxy-fuel combustion, hydrogen combustion, oxygen enrichment, and carbon capture for sequestration can help support your decarbonisation goals.

Technologies that Support Decarbonising Iron and Steel Production

Low Carbon Hydrogen

Low carbon hydrogen can displace fossil fuel in combustion-intensive processes, like reheating furnaces, and in the production of Direct Reduced Iron (DRI), for both reduction and heating; DRI can be a source of low-carbon-intensity iron units for steelmaking.

Renewable Energy Sources

Investment in dedicated incremental renewable electricity generation can support powering your process to net-zero, for example, by supporting renewable hydrogen production through electrolysis.

Oxygen-based Technologies

Oxy-fuel combustion and/or oxygen enrichment can be used for melting and heating to improve process thermal efficiency and reduce fossil fuel consumption.

Carbon Capture for Utilisation/Sequestration

Carbon capture, transportation, and sequestration can potentially drive your process to net-zero. Alternatively, carbon monoxide can be separated from process streams and recycled to the blast furnace.

How can low carbon hydrogen help decarbonise steel production?

Introducing hydrogen can provide incremental benefits in carbon emissions reduction on the way to full conversion and decarbonisation.

As both an energy carrier and a reducing agent, low carbon hydrogen can be introduced at integrated mills and mini-mills alike to replace fossil fuels in both ironmaking and steelmaking processes.

How can hydrogen help produce low carbon steel?

Today, natural gas and coal are used across a variety of processes throughout the steelmaking supply chain, even those that have electrified steelmaking to reduce emissions (direct reduced iron and electric arc furnace steelmaking). Moving forward, low carbon hydrogen can be introduced as a blended solution―and eventually adopted as a 100% replacement―to fill the role that fossil fuels hold today and to help transition one of the hardest-to-abate industries to net-zero.

Blast Furnace Iron Production

Hydrogen can be used in place of coke as a reducing agent in blast furnaces.

Direct Reduced Iron Production

Hydrogen can be used in the production of Direct Reduced Iron (DRI), for both reduction and heating.

Melting and Heating Processes

Oxy-fuel combustion, using hydrogen as a fuel, can lower emissions in processes such as blast furnace stoves, EAFs, reheat furnaces, and ladle preheating.

Renewable Energy

Clean, renewable energy from wind, solar, or hydropower is generated using zero emissions.

Carbon Capture

Oxy-fuel combustion with hydrogen as a fuel can be used to concentrate CO₂, making it easier to capture.
