The project successfully initiated retrofitting and methodological groundwork essential for the pilot-HPSR plant demonstration trials that will be conducted until the end of 2025. The retrofitting and modification work on the 5-ton pilot DC EAF have progressed as planned, and the demonstration campaign is expected to be completed in 2026. Several supporting laboratory trials have been performed, and the optimal operation parameters have been evaluated via experimental and theoretical approaches. Iron ores and sidestream materials have been provided by project partners both for laboratory and pilot trials.
Numerous laboratory-scale HPSR trials have established procedures both for processing various iron ores and sidestreams, and how to implement in situ analysis methods, such as optical emission spectroscopy. Project’s modeling work, on the other hand, has focused on developing a first of its kind dynamic mathematical HPSR model, support for hydrogen addition into retrofitted EAF, and bridging the gap between laboratory experiments and theoretical models. The results have been reported and disseminated in projects’ public deliverables, conference presentations, and open access peer-reviewed publications.
To address the environmental footprint, process effectiveness, and competitiveness, the life cycle assessment & cost (LCA & TEA) analyses have been started, the benchmark processes have been defined, and HPSR system boundaries and critical performance factors have been identified. In addition, potential uncertainties and future scenarios have been defined. Data from H2PlasmaRed’s laboratory trials have been used as a reference, supported by thorough discussions with pilot-HPSR personnel regarding the scalability factors. Process flow diagrams of various reactors were drawn accordingly. Environmental and techno-economic indicators which will be used to communicate the results were selected. To determine the risks associated with the use of critical raw materials within the HPSR value chain, criticality analysis is being conducted.
