Liquid fuel is in high demand because it has high energy density due to its inherent chemical bonds, but unfortunately, fossil fuel supplies and related liquid fuel products are quickly diminishing. One solution is to explore non-fossil renewable H2/CO fuels or even sustainable hydrogen fuel. The technical progress of CO2 capturing makes CO2 a potential feedstock for renewable syngas fuel (a gas mixture of H2/CO). This alternative solution is to develop more efficient and durable electrochemical reduction conversion system such as a solid-oxide electrolytic cell to generate the H2/CO syngas fuel by co-electrolysis of CO2 and H2O. The clean fuel can directly generate electricity using a SOFC power system at relatively high energy efficiency. To further combat the energy issue, especially for onboard energy storage requiring of significant high energy density, one proposition is the direct synthesis of liquid fuels using the syngas via the FTS technique. As a whole, the solid oxide electrolysis process at high temperature can use the CO2 feedstock to subsequently produce non-fossil synthetic fuels. More R&D efforts potentially reduce CO2 emissions and decrease environmental concerns. The utilization of CO2 as the starting material for fuel production is highly desirable, gradually reduces CO2 contribution to the environment, and creates a positive impact on the global CO2 emission levels.
