CO2-reduced Steel Production
Achieving the climate objective of limiting the temperature increase to 1.5 °C at the end of the century is the major global challenge that the steel industry has also accepted with its intention to substantially cut CO2 emissions. To this end, K1-MET GmbH is working on two new technology pathways. On the one hand, the focus is on shifting from a carbon-based energy system for steel production to a hydrogen-based one. For this, aspects such as efficient hydrogen production with the integration of renewable forms of energy and direct steel production with hydrogen as a reductive are to be examined. The emphasis here is on process developments and upscaling. The objective of the second technology pathway is the sustainable use of CO2 generated by the process using existing steel production technology. Here, conversion processes are developed, e.g. together with hydrogen to methane, to generate renewable energy sources or industrial raw materials from CO2. This decarbonization, i.e. replacing carbon, oil or natural gas as the source of energy, can only be successfully implemented in stages and in conjunction with the conversion of the energy System.
