P2X Phase II

Research, validation and implementation of Power-to-X concepts

P2X Phase II

The Kopernikus project for the energy transition "P2X" is researching technologies that can be used to efficiently store and distribute electricity generated from renewable sources. The focus is on the electrochemical conversion of electricity into material energy sources and chemical raw materials using Power-to-X processes.

In collaboration with the Technical University of Munich (TUM), FENES is developing an energy system model that will enable the Power-to-X (PtX) technology paths selected by the P2X consortium to be examined in terms of their impact on the national economy, the energy system and climate protection. In addition, PtX technologies that have not yet been covered in P2X are mapped in the model. These are, for example, Power-to-Heat or pathways for coupling the electricity and non-energy consumption sectors.

In the existing FENES energy model, which was developed as part of SPIKE (System Analysis and Integration of Power-to-X in the Context of Renewable Electricity as Primary Energy), the energy system has so far been mapped without a local resolution, energy grids and the exchange with neighboring European countries. Flexibility options and energy storage are also only modeled in a simplified way. For this reason, the energy model for the "P2X-2" joint project is being adapted accordingly. The spatial resolution is based on a division of the map of Germany into defined grids. The modeling of fluctuating renewable generation and the load profiles in the consumption sectors takes place in these grids. Both temporal and local adjustments of PtX technologies and processes in energy-intensive industry are considered as flexibility options. Common short-term and long-term storage systems are integrated as energy storage systems. In addition, interfaces are created in the model that make it possible to interact with a grid model and a model for the European electricity exchange at TUM.

Based on the modeling results, the respective Power-to-X processes can be examined with regard to their benefits for climate protection and the energy transition and the most promising paths can be identified. In addition, the effects of the use of Power-to-X technologies in the energy system can be investigated.
