Project thesis | Waste heat utilisation in a stainless steel plant through combined heating and cooling
BGH Edelstahl Lugau GmbH generates large amounts of waste heat at very different temperatures, whereby the waste heat potential has so far only been utilised to a small extent for other thermal applications.
The use of chillers as heat pumps is seen as a general approach to improving waste heat utilisation and reducing CO2 emissions. The existing heating water network and the cooling water network are to be linked in a suitable way for combined heating and cooling.
The work focusses on
- Presentation of the current status of the heating/cooling infrastructure
- Creation of a catalogue of requirements for heating and cooling consumers (quantities, qualities, tolerances)
- Modelling the heating and cooling infrastructure as a digital twin, e.g. in STANET
- Concept development for heat management with combined heat, cooling and power generation (CHP)
- Hydraulic variant analyses and calculations
- Determination of space requirements and space capacities for new and additional CHP plant components
- Energy-economic and ecological evaluation of the concepts and derivation of recommendations
The results are to be summarised in the form of a final report including annexes.

Master's project | Networked energy technology laboratories - development of a system concept
The ING faculty has several energy technology laboratories in the Nieperbau building. Due to the technical condition of some components and the growing challenge of researching and optimising networked energy systems, an overall concept for the expansion and networking of the energy technology laboratories is to be developed. The existing laboratory equipment and ideas from various project outlines are to be taken into account and the availability and costs of the new components are to be researched.
The aim is to network various energy conversion systems, energy storage systems and energy consumers with each other and to use them in a system network for laboratory practicals as part of teaching and for investigating further research questions.
The work focuses on
- Reviewing previous studies and documents, liaising with laboratory staff and professors
- Creation of a catalogue of requirements regarding the type, size and boundary conditions of the individual components
- Presentation of the possible interactions between the components
- Development of proposals for possible teaching practicals
- Research into laboratory components and cost estimation
The results are to be summarised in the form of a final report including annexes.

Market analysis of hydrogen technologies
The National Hydrogen Strategy (NWS) published by the German government in June 2020 is intended to make a significant contribution to establishing hydrogen as a core element of the energy transition and driving forward the decarbonisation of the energy system. The NWS is also intended to accelerate the market ramp-up of hydrogen technologies.
As part of its activities, an analysis of the existing market availability of H2 technologies will be carried out. The aim of the analysis is to show in which areas of the process chain there is a need for development and to what extent the establishment of H2 technologies is already possible today according to the current state of science and technology. The process chain includes the elements of production, transport and distribution, storage and consumption.
The following focal points are to be addressed as part of the project work:
- Development of the hydrogen value chain based on a predefined process chain
- Researching the market availability of H2 technologies: a) production, b) transport and distribution, c) storage, d) consumption
- Creating fact sheets on the individual technologies with relevant data: a) Creating a fact sheet template (e.g. with Excel), b) Determining the relevant data (e.g. development status, GHG impact, company/institute, performance classes, etc.), c) Developing the fact sheets based on the research
- Derive the research and development potential along the H2 value chain
