About

I am passionate about the energy transition, with a strong focus on the heating transition (Wärmewende). I work as a Development Engineer at a heat pump company, contributing to the development of efficient and sustainable heating solutions. My background is in Sustainable Energy Technology (TU Delft), with expertise in heating and cooling systems, district energy, and thermal energy storage. I am particularly motivated by turning technical knowledge into practical solutions that support a climate-neutral energy system.

Master thesis: Co-Simulation of a District Heating and Cooling System in Combination with Mine Thermal Energy Storage - A Case Study in Germany Developing a co-simulation of a district heating and cooling system in combination with Mine Thermal Energy Storage (MTES). This contains the following: • Setup of a new heating and cooling system with integration of the MTES system. • Setup of the control strategy for the new system. • Development of the MTES model in Python. • Development of the district heating and cooling model in Modelica (Dymola). • Development of an orchestrator in Python to run the co-simulation. • Analysis of the technical, environmental, and techno-economic performance of the resulting system. This master thesis was conducted within the European PUSH-IT Project. This EU-funded project aims to demonstrate the full-scale application of high-temperature heat storage in geothermal reservoirs.
