LanzaTech Porsgrunn Project

LanzaTech and Eramet announced plans to develop a first-of-a-kind integrated carbon capture, utilization, and storage (CCUS) project at Eramet’s manganese alloy smelter in Porsgrunn, Norway. The project will capture furnace off-gas from the smelting operation and convert a portion of the contained CO₂ into approximately 24,000 tonnes per year of ethanol using LanzaTech’s gas fermentation technology, creating a low-carbon chemical and fuel intermediate. The remaining concentrated CO₂ stream may be conditioned for permanent geological storage in a second project phase, subject to feasibility and financing. Front-end engineering and design is being supported by Fluor with sustainability and site integration work led by Sweco, and Brookfield Asset Management holds a right of first refusal to provide project financing. The partners are targeting initial operations around 2028, positioning the project as a scalable industrial decarbonization pathway for hard-to-abate metallurgical emissions while integrating both carbon reuse and long-term storage.
