The aim of the project is to develop, demonstrate and evaluate a flexible and scalable system for coupling the electricity, gas and mobility sectors via hydrogen as an energy carrier. At the core of the system is a metal hydride storage facility that is connected to the various energy and demand sectors via different system components. For example, by means of an electrolyzer, energy can be flexibly taken from the power grid and stored in the form of hydrogen. If required, electrical energy can be supplied by a fuel cell. For this purpose, with the aid of a membrane filter system, hydrogen from the natural gas grid can be used as well as the stored hydrogen. In addition, the system has a link to the mobility sector, which can be provided with hydrogen at elevated pressure levels using metal hydride compressors.

Parallel to the practical demonstration, the overall concept is modelled with digital twins. This allows for an evaluation of the interaction of the individual system components in the context of the overall energy system.

Within the framework of the project, the Institute of Environmental Technology and Energy Economics (IUE) is significantly involved in the simulation-based optimization of the overall system and the optimization of the system control. In addition, a technical, economic and environmental evaluation of the system in the overall context of the energy industry is being carried out by the IUE.
