STERG internships

STERG offers internships for conducting small research projects. This includes the opportunity for foreign students to conduct final year projects or Masters projects with the research group. Co-supervision from STERG would need to be approved.

We typically seek interns in all fields relevant to our research, in particular

  • Solar optics
  • Central receiver
  • Thermal storage.

Projects can vary from theoretical and computer modeling to experimental work. We advise making contact at least three months prior to the envisaged internship date to allow for identifying a potential host and topic as well providing sufficient time for visa application (if needed).

Available project for 2024: Integration of high-temperature heat pumps (HTHP) in industrial processes

A thesis or internship opportunity is available for SA Engineering students.

The topic of high-temperature heat pumps is very relevant in the industry, especially for applications of waste heat utilization and heat recovery (in Europe as well as in South Africa). By transitioning away from fossil fuels and increasing energy and resource efficiency, the CO2 footprint can be drastically reduced.

This project will be co-supervised by Osnabrueck University of Applied Sciences (HOS, Prof. Koke) and Stellenbosch University (SU, Prof. McGregor). The work can be carried out in Germany and/or Stellenbosch.
