ArcelorMittal and partners Mitsubishi Heavy Industries (MHI), BHP, along with Mitsubishi Development, have successfully started operating a pilot carbon capture unit on the blast furnace off-gas at the ArcelorMittal Gent steelworks in Belgium.

The pilot carbon capture unit will operate for one to two years to test the feasibility of progress to full-scale deployment of the technology, which would be able to capture a sizeable portion of the Ghent site emissions if successful.


The pilot carbon capture unit, trialling MHI’s carbon capture technology, will be testing initially with blast furnace and reheating furnace gas, and has the potential to capture steelmaking gases such as reformer flue gas from a direct reduced iron plant.


The first phase of the trial involves separating and capturing the CO2 from the top gas from the blast furnace at a rate of around 300 kg/d of CO2. The second phase involves testing the separating and capturing of CO2 in the off-gases in the hot strip mill reheating furnace, which burns a mixture of industrial gases including coke gas, blast furnace gases and natural gas.


The development of the carbon capture solution at Ghent could feed into multiple CO2 transport and storage projects under development in the North Sea region, the companies claim. The European Union has an objective to achieve an annual CO2 storage capacity of 50mn tonnes by 2030, proposed under the Net Zero Industry Act.


In related news, from greater Copenhagen’s Avedøre power station in Denmark, Ørsted is to sell a further 1mn tonnes of carbon removal over a 10-year period to Microsoft. The site is part of the bioenergy carbon capture and storage project, the Ørsted Kalundborg CO2 Hub.


This new agreement builds on an existing commitment by Microsoft to buy 2.67mn tonnes from Asnæs Power Station, bringing the total purchase under contract to 3.67mn tonnes of CO2.


As part of the Ørsted Kalundborg CO2 Hub project, set to be operational by 2026, Ørsted will establish carbon capture at the wood chip-fired Asnæs Power Station in Kalundborg in western Zealand and at the Avedøre power station’s straw-fired boiler. The 430,000 t/y of biogenic CO2 from the combined heat and power plants will be shipped to a permanent storage reservoir in the Norwegian part of the North Sea.
