German steel group Salzgitter expects to take a new hydrogen electrolyzer into operation at the end of 2020, which will cover requirements at its main steelmaking arm.
“An essential cornerstone of our innovation activities consists of reducing the CO2 emissions of the integrated steel production at the Salzgitter site. Together with the Fraunhofer Society and other partners, we are expediting the SALCOS, Salzgitter Low CO2 Steelmaking project. The project’s engineering approach targets the direct avoidance of CO2 emissions in the production process itself by using hydrogen to gradually replace the carbon necessary for steel production based on iron ore. We are convinced that avoidance of CO2 emissions in steelmaking is a more sustainable and also energy-wise more sensible way compared to carbon capture and usage or carbon capture and storage. “
“Moreover, according to the latest scientific findings, SALCOS® offers the best combination of energy efficiency and CO2 reduction potential compared to other industrial concepts. A unique selling proposition consists of the innovative combination of the technologies available today and established in the industry that can, therefore, be implemented quickly from a technical standpoint as soon as the requisite framework conditions for sustainable operation have been set in place by policymakers and society. In the first stage of development implementable through to 2025, SALCOS could reduce the CO2 emissions from steel production at the Salzgitter location by around one quarter and, in the final stage of implementation through to 2050, by up to 95%.”
