STEP carbon capture in which three molten carbonate electrolysis in series are driven by a concentrator photovoltaic. The maximum power point photovoltage of one Spectrolab CPV is sufficient to drive three in series carbon dioxide splitting 950°C molten Li2CO3 electrolysis cells (Licht et al., 2011).Influence of the temperature on the Li–Na–K (43.5–31.5–25 mol%) eutectic at 600°C for a H2O/H2 ratio in pressure of 1 bar and a CO pressure of 10−1 bar.
