A solar tower fuel plant for the thermochemical production of kerosene from HO and CO.

Developing solar technologies for producing carbon-neutral aviation fuels has become a global energy challenge, but their readiness level has largely been limited to laboratory-scale studies. Here, we report on the experimental demonstration of a fully integrated thermochemical production chain from HO and CO to kerosene using concentrated solar energy in a solar tower configuration. The co-splitting of HO and CO was performed via a ceria-based thermochemical redox cycle to produce a tailored mixture of H and CO (syngas) with full selectivity, which was further processed to kerosene.
