Popis: White syngas is produced by co-electrolysis of carbon dioxide and water. As syngas is one of the essential petrochemical foundations of industrial chemistry, the high temperature co-electrolysis can induce a possibility for the defossilization process in conventional petro chemistry. Therefore, it is necessary to discuss the proper technological framework in the scopes of supply of CO2, electrochemical performance of Solid Oxide Electrolysis Cells (SOEC) and products of white syngas. In future Power-to-X scenarios with a 100 % share of renewable energy, it is fundamentally important to calculate process-related carbon dioxide emissions from the total CO2 emissions. Also, we show the superior performance of co-electrolysis to different electrolysis technologies. As a standard of comparison, we introduce the Fossil Carbon Equivalent (FCE) to clarify the impact of white syngas on industrial chemistry by matching energy demand, need of installed electrolysis capacities, consumption of carbon dioxide and substitutable amount of fossil resources.
