Modelling of Hydrogen Technologies- The focus is on modeling tasks for mapping individual components, such as electrolysis, storage, and fuel cells, via their specific energy and mass balances in connection with the overall system of the production chain (e.g. power feed from the grid or directly).- Preparation and research on existing model developments and technology data- Support in the development of corresponding models and their integration into more complex systems- Support in the implementation of simulations, in particular, data preparation and analysis before and after a simulation run

- Creation of 3D CAD models and the corresponding 2D drawing derivations for engine housing and pistons as well as crankshaft with Siemens NX 10- Assessment of manufacturability and assembly in coordination with the production areas
