Abstract

The production of syngas by simultaneous splitting of direct-air-captured CO2 and H2O via a solar thermochemical redox cycle is a competitive alternative to electrolysis-based pathways. Isothermal or near-isothermal operation using high-entropy oxides that are readily available, robust, and flowable is recommended on the basis of practical considerations and improved performance, both mechanical and thermodynamic. Ongoing research efforts should direct attention toward devising compatible thermal energy storage technologies and/or incorporating hybrid solar-electric heating to (1) mitigate the effects of solar intermittency and (2) provide a continuous feed for downstream gas-to-liquid processing. The path forward involves funding the development and characterization of fully integrated laboratory systems.

太阳能热化学燃料:现状与展望
通过太阳能热化学氧化还原循环同时分解空气直接捕获的二氧化碳和水来生产合成气是电解途径的一个有竞争力的替代方案。基于实际考虑和改进的机械和热力学性能,建议使用易于获得、坚固且可流动的高熵氧化物进行等温或近等温操作。正在进行的研究工作应该把注意力集中在设计兼容的热能储存技术和/或结合混合太阳能-电加热上,以(1)减轻太阳能间歇性的影响,(2)为下游的气转液处理提供连续的原料。前进的道路包括资助开发和描述完全集成的实验室系统。
