Integration of a rSOC-system to industrial processes

Abstract

The reversible operated high temperature solid oxide cell system (rSOC-System) seems to be a promising technology, enabling our future energy system to cope with the challenges of the transition to renewable electricity production and electrification. The rSOC-System provides energy storage capabilities and connects different energy carriers. This work provides insights into the coupling possibilities of such a system to industrial processes. Based on previously published investigations a flowsheet for the rSOC-System is chosen and described. To enable a quantitative analysis of the interaction with industries, a simulation model for this rSOC-System is created. This model is used for creating energy conversion and efficiency maps, which are then discuss with respect to the system behaviour. The increase of the system’s conversion efficiency is determined for a selection of thermal coupling and operation scenarios. This work concludes with an analysis of the scenario dependent effect of heat coupling and the consequences for the integration of a rSOC-System to industrial processes.
