H₂Giga is one of three hydrogen lighthouse projects funded by the Federal Ministry of Education and Research and contributes to the implementation of the National Hydrogen Strategy. The overall aim is to bring electrolysers into series production and enable efficient operation. The "eModule" sub-project is concerned with the modelling, automation, integration and optimization of electrolysis modules.

Together with the project partners DLR Institute of Technical Thermodynamics, HSU Hamburg, Semodia, VDMA Power-to-X for Applications, this sub-project at TU Dresden is developing standard integration profiles in the P2O-Lab, in which various operating and usage scenarios of electrolysers can be mapped in a reference plant. The aim is to determine as precisely as possible how the individual electrolyser components and the electrolyser as a whole behave under volatile conditions on the grid and consumer side and which specific requirements they are subject to. In dialog with industry, the project partners want to draw up a catalog of requirements and enable manufacturers of electrolysers and components to gather experience before the actual series production of electrolysers begins and to align the systems with future requirements.
