Abstract: The coupling of renewable energy electrolysis for hydrogen production and methanol synthesis can not only reduce CO2 emissions, but also achieve on-site consumption of renewable electricity. In this paper, an integrated system of solid oxide electrolysis cell (SOEC) with CO2 to methanol (SOEC-CO2tM) is studied: (1) The energy-intensive SOEC is combined with the intense exothermic CO2tM, (2) the heat of the system is redistributed to energy realize cascade utilization and electrification transformation of public works to further improve energy efficiency, (3) multi-dimensional techno-economic assessments are performed to reveal the development potential. The results show that the carbon utilization and carbon emissions of the new process are better controlled. The energy efficiency of the SOEC-CO2tM process after electrification transformation is also higher than that of traditional methanol synthesis processes. The production cost of methanol is currently higher than the market price, which does not give the SOEC-CO2tM process a competitive advantage. However, when considering carbon taxes and changes in raw material costs and renewable electricity prices, the future cost of the SOEC-CO2tM process can be comparable to or even more favorable than other processes. Through the research and analysis, we aim to explore the potential integration of SOEC and CO2tM process.
