We’ve officially reached the midpoint of our project. This is a great moment to look back at what we’ve achieved so far and look ahead to what’s coming next.
Key milestones achieved:
✅ Definition of reduction conditions using carbon-free reducing gas atmospheres, including scenarios with and without NH₃ admixture
✅ Completion of a round robin to mitigate risks of misleading results in the chemical analysis of pellets and fines
✅ Dissemination of results through 1 publication, 2 conference papers, and 2 conference presentations
✅ Organisation of a two-hour stakeholder workshop, featuring valuable insights from project partners and an interactive session to foster knowledge exchange and collaboration
✅ Modification of the test rig to enable systematic testing of H-DRI breakage behaviour
Within the second half of our project, we will focus on:
➡️ Execution of direct reduction (DR) experiments, and subsequent trials with H2-reduced DRI including briquetting of resulting DRI-fines and their reuse-properties in DR
➡️ Systematic assessment of reoxidation behaviour under realistic transport and storage conditions to adapt and optimise a container design for loading, transport, and storage, tailored to the specific properties and requirements of H-DRI
➡️ Quantification of crack formation and fines generation during handling, with the objective of assessing material reuse potential and developing mitigation strategies
➡️ Further and detailed experimental evaluation of passivation approaches to assess risks such as self-heating, ignition, and local explosions during transport and handling
➡️ Identification of critical safety parameters by correlating variations in H-DRI quality (e.g. degree of metallisation, gangue content, particle size distribution) with associated hazards and risk profiles
We are excited about the progress so far and even more about what’s ahead!
Let’s move the future forward – safely.
