The project aims at a comprehensive analysis of the challenges in integrating the hydrogen system to stabilise the electric grid. For this purpose, the required capacity of the hydrogen systems in the electric grid is determined with different combinations of renewable energies and synchronous machines. Numerous scientific challenges arise from the complex interplay of energy supply and demand of the subsystems involved (electric energy system, hydrogen systems, energy market).

The Professorship for Corporate Environmental Management and Sustainability faces the central challenges of consistently counteracting the increasing consumption of resources and the emissions induced by it, as well as achieving the currently set ambitious goals of climate and resource protection. The Renewable Energy Sources Act (EEG) can make a decisive contribution to this. In the present project, the professorship's first task is to determine various indicators for evaluating the ecological and economic sustainability of the hydrogen system. Secondly, based on this, a sustainability assessment (e.g. by means of life cycle analysis, analysis of rebound effects and instruments of controlling) of this very system will follow with the aim of determining and interpreting critical factors and key figures. Finally, corresponding recommendations for action will be derived with regard to the advantages of using hydrogen systems to stabilise the electricity grid.

Project period: 01.01.2023 to 31.12.2024

This project is financed by the European Union and co-financed by tax funds on the basis of the budget passed by the Saxon state parliament.
