Abstract
Power-to-Gas is an efficient way to use the existing natural gas infrastructure to store renewable electricity. Solid Oxide Electrolysis (SOEC) technology has the potential to achieve better efficiency by integrating it with a CO2 source for synthetic fuel production e.g. SNG, methanol, DME etc. There could be an advantage in combining these processes as one is highly exothermic while the other is heat demanding. Another advantage of using SOEC is that it can be used for CO2/H2O co-electrolysis, which could be an interesting choice for producing syngas at high temperature for further fuel conversion. In this study the Aspen plus simulator is used for both component and system modelling.
The comparative analysis showed that more heat 0.81 kW is available for CO2/H2O co-electrolysis based system compared to 0.51 kW for steam electrolysis while the overall efficiency ~75% and final product composition remains the same for both systems.
