The Saarland steel industry, with the companies Dillinger and Saarstahl, plays a key role as an industrial consumer in the strategic development of the regional cross-border hydrogen value chain. Use of hydrogen is required to reduce emissions from processes in the steel industry.

In 2020, Dillinger and Saarstahl have already put a hydrogen-based steel production plant– the so-called coke gas injection system – into operation at both blast furnaces operated by the joint subsidiary ROGESA Roheisengesellschaft Saar mbH. Thus, the two companies are further cutting their carbon emissions while also creating the conditions for practical use of green hydrogen. Within the scope of the so-called “H2SYNgas” innovation project, a technology is being developed, which will enable the use of the company’s own process gases and, in addition, substantial quantities of hydrogen for the blast furnace process. The synthesis gas generated from the company’s own process gases will be enriched with hydrogen. This hydrogen-rich mixed gas will then be used as a reducing agent for the reduction of iron ore, replacing coke in the blast furnace process and thus avoiding CO2 emissions. Following the coke gas injection, SHS – Stahl-Holding-Saar is set to take the next step on the road to CO2-neutral steel production in the Saar region by implementing this new innovative technology.
