Process simulation of the iron energy storage cycle with AspenPlus
Prozesssimulation des Eisenkreislaufs zur Energiespeicherung mit AspenPlus
29.07.2025
Masterthesis
Large-scale energy storage is a critical challenge for achieving a green economy. The metal energy cycle presents a promising approach by allowing cyclic combustion and reduction processes without CO2 emissions. Among potential energy carriers, iron powder stands out due to its favorable combustion characteristics. To accurately compare the iron cycle and its different iron reduction methods to competing energy storages, a simulative process analysis is needed.

Microfluidic PEM electrolyzer for hydrogen production
Mikrofluidischer PEM-Elektrolyseur für die Wasserstofferzeugung
14.07.2025
Masterthesis, Bachelorthesis
Hydrogen has been recognized as one of the most promising pathways for decarbonizing the energy sector, while providing the required energy demands in an environmentally friendly manner. Proton exchange membrane (PEM) electrolyzers are a key technology for hydrogen production. However, for a large-scale adoption, enhancements in long-term operations are important. The durability of a PEM cell is negatively influenced by leaching of catalyst ions. To tackle this problem, it is of critical importance to understand the movement of metal ions near the catalyst layer and through the membrane. Novel experimental methods, such as fluorescence microscopy, can be used to investigate the electrochemical reaction and the transport of ions in a microfluidic PEM electrolyzer.
