Helix Carbon has built an electrolyzer-based process that converts carbon dioxide from blast furnace exhaust back into carbon monoxide, which can be reinjected into the furnace to help reduce iron ore. CEO David Brown says the system can process raw, unpurified exhaust directly, unlike most electrolyzers that require concentrated CO2 feedstock. The company says this reduces the amount of coke needed in iron production.
