Yes, the linked paper describes it in detail. They also avoid going through an electrolysis-of-water step to generate the H2, it all happens in situ (from the linked paper). The use of the ceria catalyst to generate the CO from CO2 has been known for a while but this looks like a notable advance: > "An additional advantage of the solar redox cycle compared with other solar approaches is its ability to co-split H2O and CO2 simultaneously or separately and therefore control the quality (both purity and stoichiometry) of the syngas in situ, consequently obtaining a tailored mixture of H2 and CO suitable for FT synthesis." > "This direct approach eliminates the energy penalty associated with additional refinement steps for adjusting the syngas mixture. In contrast, the electrolytic pathway (also called “power-to-X”) requires the production of substantial excess H2 by water electrolysis using solar electricity...
