AMBARtec and Rouge H2 Engineering are developing processes for climate-friendly steel production. The new technology can soon be used with little effort - without costly conversions in the process chain.<\/strong>\n\u00a0\n
\n
\nDresden, 10 July 2025 \u2013 <\/i>AMBARtec and Rouge H2 Engineering are set to collaborate closely in the future to bring the chemical looping hydrogen process to market maturity. This process can be used to produce clean hydrogen and concentrated carbon dioxide from blast furnace gas and other steel mill gases. It is based on the steam-iron process, which can be used to produce high-purity hydrogen by reducing and oxidising iron oxide or iron nuggets. The highly concentrated CO\u2082 obtained can be effectively utilised in CCU or CCS processes.\n\u00a0
\n
\nThe Chemical Looping Hydrogen process<\/strong>\n
\nThis two-stage process uses iron oxide (FeOx) to convert carbon-containing gas mixtures into hydrogen (H\u2082) and carbon dioxide (CO\u2082). \u2018Our collaboration aims to optimise the process for blast furnace gases and implement it in steelworks,\u2019 reports Uwe Pahl, Chief Technology Officer at AMBARtec. Blast furnace gas, coke oven gas and converter gas can thus be processed to generate high-quality hydrogen. The high-purity carbon dioxide produced during this process can be utilised as a material (CCU) or stored (CCS). The precondition for this green transformation of the steel industry is that the CCS Act, which is currently being revised, must authorise the storage of CO2 from the steel industry. 'This gives the steel industry the chance to make its production more climate-friendly without having to invest heavily in converting the entire process chain. This will ensure that steel production in Europe remains competitive despite the stringent climate protection requirements,\u2019 emphasises Uwe Pahl\n\u00a0\u00a0
\n
Partner from the steel industry<\/strong>\n
\nThe EU project H2Loop* provides the framework for this cooperation. \u2018We are combining our expertise in iron oxide nuggets and our experience in plant operation with the knowledge of our colleagues at Rouge H2 Engineering in the processing of residual gases,\u2019 explains Matthias Rudloff, CEO of AMBARtec.\n

\nIn addition to Rouge H2 Engineering, the project also involves two partners from the steel industry. \u2018With their input, we will align the process and associated plant technology with real conditions in steelworks from the beginning and demonstrate this at our partner's premises,\u2019 emphasises Matthias Rudloff. \u2018We look forward to receiving constructive support from other steel companies.\u2019\n
\n
\nThe role of iron oxide nuggets<\/strong>
\nBlast furnace gases contain relevant quantities of carbon monoxide (CO) and hydrogen. If these gases are added to iron oxide nuggets under the right conditions, the iron oxide is reduced and carbon dioxide and steam are released.\n
\n
\nFeOx + CO\/H\u2082 -> FeO + CO\u2082\/H\u2082O\n
\n
\nThe carbon dioxide is separated and made available for utilisation or storage, for example via CCS.\nIn the second step, the reduced iron oxide nuggets are re-oxidised using steam.\nThis process produces high-purity hydrogen, which can be used as both a material and an energy source.\u00a0\n\n\n\n\n\n\n\n\n<\/div>\n<\/p>\n\n\n
