TransHyDE-Sys-MechaMod

TransHyDE-Sys is a system analysis project and a joint project within the lead project TransHyDE. In addition to the system analysis, there are also implementation and research projects on the topic of H2 transport in the lead project. As a cross-sectional project, the system analysis performs a special function: On the one hand, essential system knowledge for the time-dependent construction and coupling of the energy infrastructures is generated with the help of own modelling and simulation work as well as ecological analyses. On the other hand, observations, analyses and requirements of the implementation and research projects are to be recorded, compared with existing knowledge and classified in an overarching manner. The results are to be incorporated into a continuously developing roadmap. This will continuously support the research and implementation projects, identify possible research and development topics for the next project phases and also provide important recommendations for action for external stakeholders.

The MechaMod sub-project of the H-BRS focuses on detailed physical-chemical modelling for all relevant mechatronic components of the gas and hydrogen transport networks, both for operation and for coupling with electricity grids. These include electrolysers, fuel cell power plants, compressors and controllers. A particular challenge here is the dependence on the gas composition including impurities. The new models will be prototypically implemented in simulators used by the partners.

The result will be differential equation and map-based models for the simulation and analysis of possible transformation paths from natural gas to hydrogen transport infrastructure, with analysis of technical limits and reliability.

Further contributions in the sub-project support a further development of methods for model comparison, a life cycle analysis, cooperation with stakeholders and road mapping.
