The topic

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.

Your Task

At VES we investigate the direct electrochemical reduction of iron oxide slurry. To evaluate this approach a detailed understanding of the system at process scale is required. During your thesis you will develop a simulative model of the iron cycle, focusing on electrochemical reduction. With this, you will give insight into the cycle and give valuable information on its efficiency and viability. Furthermore, you will evaluate the potential of direct iron electrolysis as the reduction step.
