Developing solar technologies for producing carbon-neutral aviation fuels has become a global energy challenge, but their readiness level largely been limited to laboratory-scale studies. Here, we report on the experimental demonstration of fully integrated thermochemical production chain from H2O and CO2 kerosene using concentrated in tower configuration. The co-splitting was performed via ceria-based redox cycle produce tailored mixture H2 CO (syngas) with full selectivity, which further processed kerosene. 50-kW reactor consisted cavity-receiver containing reticulated porous structure directly exposed mean flux concentration 2,500 suns. A solar-to-syngas conversion efficiency 4.1% achieved without applying heat recovery. This fuel plant operated setup relevant industrial implementation, setting technological milestone toward sustainable fuels.
