Advances and Challenges in High-temperature Electrochemical CO2 Conversion Technology | Chapter 9 | Advances and Challenges in Science and Technology Vol. 4

 During ancient times century, CO2 emissions about the world have stretch to grow at an astonishing rate. In current years, accompanying the proposal of the global aim of “carbon retaliation”, high-temperature CO2 electrolysis science based on solid group of chemical elements electrolysis cell (SOEC) has escorted in a rapid development event. SOECs operating at elevated hotnesses can not only make full use of environmental pollutant heat but also convert CO2 into hydrocarbon fuels or extreme-value-added synthetic products by way of electrochemical reactions. Currently, multiple nations around the world have redistributed various extreme-temperature electrochemical CO2 conversion projects. In 2017, Haldor Topsøe A/S (Denmark) stated the world’s first monetary CO2 electrolysis system, which can produce CO vapor through SOEC electrolysis of CO2, with a result capacity of up to 10 Nm3 CO2/h. In 2019, Sunfire GmbH (German) grown a high-temperature co-electrolysis parade system that can product syngas at 4 Nm3/h rate. In 2020, the University of Aarhus (Denmark) reported a CO2 methanation catalyst based on SOEC, that can upgrade biogas to pipeline bulk methane in a 10 Nm3/h exploratory device. Compared to the high-hotness water electrolysis for hydrogen production, the scale of the extreme-temperature CO2 electrolysis device is nearly small. With the increasing demand for strength density and capacity density of CO2 conversion tools in various new use fields, further research and development is necessary to overcome the challenges of extreme cost and low stamina in large-scale application and commercialization.
