Expansion of hydrogen infrastructure
ArcelorMittal aims to achieve carbon-neutral steel production at its European sites by 2050 and to reduce emissions by 30 percent by 2030. “The German flat steel sites in Bremen and Eisenhüttenstadt are fully integrated into the Group’s strategy on climate neutrality”, the company explains. Two blast furnaces will be converted at the sites in order to blow in natural gas and reduce CO₂ emissions. With the planned expansion of the hydrogen infrastructure in Germany, ArcelorMittal intends to build a large industrial plant for the direct reduction of iron ore (DRI) in Bremen and a DRI pilot plant in Eisenhüttenstadt in combination with electric arc furnaces by 2026.Own process gases and hydrogen
With ‘H2Syngas’, Saarstahl and Dillinger rely - together with the engineering company Paul Wurth (part of the SMS group) -, on the use of their own process gases and the use of considerable amounts of hydrogen in the blast furnace process. The corresponding pilot plant was built in cooperation with Paul Wurth.
“The new process developed by Paul Wurth – known as dry reforming – enables the conversion of the coking plant gas produced in the coking plant into a hot reducing gas or synthesis gas”, explains Saarstahl. This is enriched with hydrogen and then used as a reducing agent for the reduction of the iron ores. The injection of the hot reducing gas into the blast furnace “leads to a considerable reduction in coke consumption and thus to a reduction in CO₂ emissions”.The green transformation is also digital
The green transformation has already begun and is setting itself high targets – but it needs digital support. According to the ifo Institute, the digital transformation of the energy industry – and ultimately the steel industry – is an integral part of the energy transition. It is one of the biggest IT projects of all time. In the future, many new and decentralised producers of renewable energy will enter the market. “These must be connected to the grid and their fluctuating production must be controlled. As a result, suppliers will have to manage large data streams, including data on feed-in or local consumption”, explains the ifo Institute. Digitisation therefore not only supports efficient production, but also a sustainable distribution of energy to steel companies. A mammoth task that must now be mastered.
