Welcome to the Institute for Thermal Energy Technology and Safety (ITES) at the Karlsruhe Institute of Technology (KIT).
The ITES uniquely embodies the energy transition: our mission is to enable innovative thermal technologies for a sustainable and safe net-zero energy supply. To this end, the ITES performs research in hydrogen safety and applications [H2], heat transfer / storage / transport using water [MPS], liquid metal [KALLA], and molten salt [FTS], efficient use of alternative heat sources [EVT], magnetohydrodynamics for fusion [MHD], numerical flow modeling [FPS], analyses of the resilience of critical infrastructures, atmospheric dispersion and impact assessment of hazardous substances (e.g. radionuclides) as well as decision support systems [RESIS].
An important part of our mission is the training and education of the next generation of practitioners and engineers through apprenticeships, lectures, internships, and theses [Lectures, Openings].

Eike Schmidt's poster presentation on ‘Investigation of heat transfer in high-temperature heat storage systems with liquid metals’ at the FVEE Annual Conference, 7-8 October 2025, Berlin, was awarded a poster prize! His poster shows how high-temperature heat storage systems can contribute to the energy system of the future and how the research in his PhD work contributes to this. In his doctoral thesis, Eike Schmidt is investigating heat transport processes in packed-bed storage systems with liquid metals as part of the DFG Priority Programme Carnot Batteries (SPP 2403).

The article “A code-to-code benchmark for magneto-convection in a horizontal duct” was published in the journal Nuclear Fusion.
Details: Liquid metals play an important role as breeding material and coolant in applications in future fusion power plants. In an international benchmark project, initiated by ITES, various research groups are comparing their findings on heat transfer in magnetohydrodynamic liquid metal flows, which they obtained using different numerical codes.

This year's Siemens Energy Challenge takes the topic of decarbonization into its spotlight. Pioneering solutions for energy transition pathways are developed by teams of MSc students who share the passion for Energy Technologies. Problems and concepts are validated by intensive interaction with customers. The student teams compete, supervised by Siemens Energy and University Partners, for the best business models that will be presented at the final event in February 2026.

The article "Design, fabrication and experimental test of a helical induction pump with rotating core" was published in the journal Magnetohydrodynamics.
Details: A new type of liquid metal electromagnetic pump for medium flowrates and moderate pressure heads has been developed at KIT. The major difference compared to existing concepts is that the central iron core, which closes the magnetic flux lines, is fabricated from a single iron piece, which may freely rotate in order to avoid magnetization losses. The pump was manufactured at KIT and tested in the liquid metal NaK loop of the MEKKA facility.

The Article "Characterization of MHD pressure losses in a mock-up of the WCLL Test Blanket Module" has been recently published in the Journal Fusion Engineering and Design.
Details: Liquid metal flows in strong magnetic fields are investigated in a scaled mock-up experiment for a test blanket module of the ITER fusion reactor. Of particular interest is the pressure distribution of the magnetohydrodynamic flow in the feeding and draining manifolds as a function of the flow rate and the magnetic field strength. Results are summarized in a pressure drop correlation.

On May 23, a Dutch delegation from the Arnhem-Nijmegen region visited the Karlsruhe Institute of Technology (KIT). Supported by EDIH AI&CS, the visit included a tour of the Energy Lab and a presentation by S. Ottenburger on systemic resilience research, focusing on AI-assisted decision-making for resilient energy planning.

Successful master's thesis in collaboration with Siemens Energy: simulation model developed for large CO₂ heat pump
Karlsruhe, May 22, 2025 - Together with Siemens Energy, Paul Schadt has developed an innovative simulation model for a large CO₂ heat pump as part of his master's thesis. The aim of the project was to simulate the power control of the heat pump using variable speeds of the compressor and expander - an important step for the future use of such systems in grid balancing services.
