Four Years of Research at the End-of-Project Meeting in Karlsruhe
At the final meeting of the Clean Circles research project, researchers gathered at the Karlsruhe Institute of Technology (KIT) to reflect on four years of collaborative work. The event featured presentations that not only reviewed past achievements but also looked ahead to upcoming projects and future challenges – with iron as a CO₂-free energy carrier at the center.

Modeling of iron oxidation and iron oxide reduction in fluidized bed reactors
2025/03/04
Master thesis
In the Clean Circles project, the potential and implementation of iron as a sustainable energy carrier are being investigated. Fluidized beds have proven to be a promising reactor concept in this context. The aim of the work is to develop one-dimensional models that enable predictive forecasts, support upscaling, and can be integrated into comprehensive process models.

Modeling and evaluation of alternative heat integration concepts for iron-based hydrogen storage
2025/02/10
Bachelor's Thesis/Master's Thesis
In this thesis, thermodynamic models are developed to evaluate and optimize alternative heat integration concepts for iron-based hydrogen storage. The focus is on efficient recovery and integration of process heat to generate both energy and cost advantages. Finally, promising concepts are sized and economically assessed, leading to concrete recommendations.

Integration and analysis of metallic energy carriers in multimodal energy systems with PyPSA
2025/02/10
Master's thesis
This master's thesis investigates the integration of metallic energy carriers into large-scale energy systems. Metallic energy carriers are first implemented in the open-source framework PyPSA (Python for Power System Analysis). Subsequently, their role and potential in future multimodal energy systems are analyzed.

How LIBS makes the composition of iron particles visible
The atomic composition of the surface of single particles during thermochemical oxidation is supposed to be analyzed non-intrusively and in situ by means of laser-induced breakdown spectroscopy (LIBS). This allows the energy release of the particles to be tracked during the process. Simultaneously to LIBS, the measurement technique Diffuse Backlight Illumination (DBI) is used to investigate the laser-particle interaction and to determine the hit quality and individual hits.
