A new energy transformation system based on carbon recycling has been proposed; it is called the active carbon recycling energy system (ACRES) and has been developed in order to reduce the emission of carbon dioxide (CO2) to the atmosphere. An experimental study based on the ACRES concept for carbon monoxide (CO) regeneration via high-temperature electrolysis of CO2 was carried out using several solid oxide electrolysis cells (SOECs). Experimental results showed that a cell with the structure Pt-LSM cermet|YSZ|Pt-LSM cermet exhibited the highest current density and CO production rates of 0.52 mA·cm–2 and 0.75 μmol·min–1·cm–2 respectively, at 900°C. On the basis of the cell's electrolytic characteristics, the scale of a combined ACRES CO2 electrolysis/iron-making facility was estimated.
