Abstract: Solid oxide electrolysis cells (SOECs) operating in co-electrolysis mode risk carbon deposition which degrade system performance and reliability. Careful operation is therefore essential to prevent carbon deposition. This presentation examines two SOEC system designs-a low utilization and high utilization configuration each employing different strategies to mitigate carbon deposition. Both design were optimized to produce methanol-grade synthesis gas (syngas). The study evaluated the impact of operating temperature on system efficiency for each configuration and applies a pinch analysis to identify further opportunity for heat integration and energy recovery. This study provides insight into SOEC system performance and approach for improving the energy efficiency of both designs using pinch analysis tool.
