According to ArcelorMittal, Utility Global’s process relies on an impermeable electrolyte to at once reduce and oxidize separate gas streams, one leading to hydrogen and the other leading to concentrated CO2 that can be readily captured and stored. 

“The hydrogen produced can be recirculated into the steelmaking process to replace natural gas, while the purity of the concentrated CO2 stream significantly simplifies and reduces the cost of subsequent carbon capture and sequestration — an important solution for decarbonizing steelmaking,” ArcelorMittal said. 

In addition to the investment, ArcelorMittal has entered into a collaboration agreement to accelerate the technology for commercial adoption, exploring opportunities to host pilot plants at ArcelorMittal facilities with an option to progress to a large-scale commercial facility at one of ArcelorMittal’s integrated steel plants.
