Fraunhofer Institute for Mechanics of Materials IWMH2DIGITAL has developed a software platform for modeling and simulating hydrogen infrastructures. By combining Fraunhofer expertise, a freely accessible data and model structure has been created that serves as a basis for further developments in the hydrogen sector.
H2DIGITAL – Digital mapping of a green hydrogen economy
Completed research project
Project description
The H2DIGITAL project aimed to develop and provide a software platform for modeling and simulating hydrogen infrastructures. The goal was to map complete hydrogen value chains from primary energy to hydrogen production and utilization. The individual model components were represented as digital twins, and the simulation of the overall model was performed using distributed co-simulation.
By pooling the concentrated hydrogen expertise of several Fraunhofer institutes, a comprehensive data and model structure was defined in H2DIGITAL, which was made freely accessible for use upon publication. In the future, a hydrogen data space comparable to Fraunhofer's industrial data space is to be created based on the defined data structures.
Fraunhofer IWM subproject:
The main task of Fraunhofer IWM was to expand the H2 Digital Ontology to semantically describe material fatigue under the influence of hydrogen. New classes and properties were defined and integrated into a process graph template. This template was converted into an Excel spreadsheet in which experts annotated simulation data. The annotated data was converted into RDF data sets and imported into a graph database. The entire workflow for RDF data generation was carried out using the Graph Designer tool developed at Fraunhofer IWM and is publicly available.
In addition, software for predicting the service life of materials under the influence of hydrogen was developed and made available for co-simulation. This prediction is based on experimental material testing under hydrogen to calibrate the analytical model.
Transfer of project results to the following Fraunhofer IWM R&D services for companies:
- Software for predicting the service life of materials under the influence of hydrogen
- Workflow for RDF data generation for the semantic description of material fatigue under H2 influence
