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. The 50-kW solar reactor consisted of a cavity-receiver containing a reticulated porous structure directly exposed to a mean solar flux concentration of 2,500 suns. A solar-to-syngas energy conversion efficiency of 4.1% was achieved without applying heat recovery. This solar tower fuel plant was operated with a setup relevant to industrial implementation, setting a technological milestone toward the production of sustainable aviation fuels.
开发用于生产碳中和航空燃料的太阳能技术已成为一项全球能源挑战，但其技术成熟度在很大程度上仍局限于实验室规模的研究。在此，我们报告了在太阳能塔配置中利用聚光太阳能实现从水和一氧化碳到煤油的完全集成热化学生产链的实验演示。水和一氧化碳的共裂解通过基于二氧化铈的热化学氧化还原循环进行，以全选择性地生产定制的氢气和一氧化碳混合物（合成气），该合成气进一步加工成煤油。这座50千瓦的太阳能反应堆由一个腔式接收器组成，该接收器包含一个直接暴露于平均2500倍太阳通量聚光的网状多孔结构。在未应用热回收的情况下，实现了4.1%的太阳能到合成气的能量转换效率。这座太阳能塔燃料工厂采用了与工业实施相关的装置进行运行，为可持续航空燃料的生产树立了一个技术里程碑。
