According to ArcelorMittal, the trial, to take place at the steelmaker’s Gent facility in Belgium, represents the first industrial testing of D-CRBN’s technology. The technology uses plasma to break the carbon-oxygen bond, converting CO₂ into carbon monoxide.

The carbon monoxide can be used as a reductant in the steelmaking process — replacing part of the coke or metallurgical coal used in the blast furnace — or as a basic ingredient in Gent’s Steelanol plant for chemicals or alternative fuel production.

The D-CRBN process requires high-purity CO₂, which can be provided by MHI’s carbon capture unit, currently being used to capture blast furnace offgases and hot strip mill reheating furnace exhaust from the Gent plant.

“We are proud to be part of this unique carbon capture and usage trial in Gent,” said Manfred Van Vlierberghe, ArcelorMittal Belgium chief executive officer. “Our team of engineers has worked hard with our partners to reach this stage — and we are thrilled that our new partner, D-CRBN, have created this new CCU technology here in Belgium.”
