Primetals is an associated partner in a research project for carbon reduction in the iron and steel industry. In the “Sequence Impulse Hydrogen” research project, a process is to be developed for blowing hydrogen into the blast furnace shaft to reduce CO2 in pig iron production.
A research project to establish decarbonization technologies for the steelmaking industry, in which Primetals is an associated partner, has been awarded a €1.8 million research grant from the European Union (EU) via the Research Fund for Coal and Steel (RFCS). The program aims to establish a process for injecting hydrogen using the Sequence Impulse Process (SIP) technology directly into the blast furnace via the shaft. With the iron and steel sector responsible for 7-10 percent of global CO2 emissions, commitments have already been made by the industry to achieve carbon neutrality in the next 40 years - some producers have stated even more ambitious goals. With low-CO2 production routes still at a relatively early stage, the majority of steel being produced for years to come will be via the blast furnace route. As such, it is imperative to find technologies which can lower the CO2 emissions of the blast furnace. Hydrogen-based reduction is a much sought after solution to support decarbonization. The technology could lower emissions from the blast furnace by up to 20 percent. However, it is accompanied by significant implementation challenges when injected via the tuyeres. Building on the available and proven Sequence Impulse Process (SIP) injection technology, as already utilized on a large blast furnace at Thyssenkrupp Steel Europe’s Schwelgern site in Germany, the research aims to simulate that hydrogen can be pulse-injected into the blast furnace shaft.
Industry consortium driving the green transformation
This project, which will conclude in 2028, brings together a consortium of major European players within the iron and steelmaking sector to take the concept from laboratory to industrial demonstration. The key technology will be designed and provided by Thyssenkrupp AT.PRO tec with furnace integration design and full-scale economic evaluation by Primetals. Analysis and modelling will be conducted by the research institutes VDEh-Betriebsforschungsinstitut, which also is the project coordinator, and K1-MET. thyssenkrupp Steel Europe will provide the industrial scale laboratory work fabrications and material burdening capabilities with the globally leading steel and technology group voestalpine completing the consortium as the hosts for the trial process with helium injection in the shaft to prove the simulations for gas distriution to be placed on an operating blast furnace at their Linz works, Austria. The research project is being funded by the EU to the tune of €1.8 million. Additional funds provided by the research partners increase the total value of the project to €3.5 million.
