Abstract: For more than three years, Salzgitter AG has been implementing measures aimed at reducing CO₂ emissions, which are combined in a project called Salzgitter Low CO₂ — Steelmaking (SALCOS). Moreover, from the very beginning, the company has been closely cooperating with the Fraunhofer Society for Applied Research; its representatives actively cooperate with our scientific experts and bring their wealth of experience to the support of such signifi cant research projects. The authors’ thoughts were based on the following requirements, which were later used to make a conceptual decision: implementation in production must be implemented as quickly as possible; reduction of CO₂ emissions should be done from the very beginning on an industrial scale; provision of the fl exibility in the use of renewable energy sources; minimization of the required specific consumption of electric energy from renewable sources in order to avoid harmful CO₂ emissions; abandoning the Carbon Leakage option; implementation of all activities in Salzgitter in order to demonstrate their commitment to the traditional production location in Lower Saxony and the conservation of relevant jobs; maintaining steelmaking capacity at about 5 million tons per year; implementation of the concept should be realized gradually and in relation to the future achievement of publicly recognized goals to reduce CO₂ emissions; further use of existing engineering design, construction and placement of equipment in order to ensure the longest possible time and increasing volumes.
