The successful transformation to a sustainable energy supply requires the use of green hydrogen. In addition to importing the gas, however, large production capacities must also be built up nationally. To make the integration of electrolysers for the production of the versatile energy carrier hydrogen more efficient, an innovative software-based toolbox for electrolysers is being developed as part of the project. This enables companies along the green hydrogen production chain to digitally analyse, evaluate and optimise use cases in advance of real implementation. This toolbox is freely configurable so that components can be easily exchanged or adapted to simulate and compare different situations, plant designs or electrolysis processes (AEL, PEM, AEM). In addition to the use of the tool in the context of project planning and in the business environment, the toolbox is implemented in the education and training of specialists. The consortium consists of companies with different competences in the field of hydrogen-based technologies and the integration of electrolysers, three universities with a focus on industrial research and experimental development as well as educational institutions for the training and further education of specialists.
