Abstract

This article provides a comprehensive overview of the work to date on the two‑step solar H₂O and/or CO₂ splitting thermochemical cycles with Zn/ZnO redox reactions to produce H₂ and/or CO, i.e., synthesis gas-the precursor to renewable liquid hydrocarbon fuels. The two-step cycle encompasses: (1) The endothermic dissociation of ZnO to Zn and O₂ using concentrated solar energy as the source for high-temperature process heat; and (2) the non-solar exothermic oxidation of Zn with H₂O/CO to generate H₂/CO, respectively; the resulting ZnO is then recycled to the first step. An outline of the underlying science and the technological advances in solar reactor engineering is provided along with life cycle and economic analyses.

摘要

本文全面概述了迄今为止利用锌/氧化锌氧化还原反应进行两步太阳能水和/或二氧化碳分解热化学循环以生产氢气和/或一氧化碳（即合成气，可再生液态烃燃料的前驱体）的相关工作。两步循环包括：（1）以聚光太阳能作为高温过程热的来源，使氧化锌吸热分解为锌和氧气；（2）锌与水/一氧化碳进行非太阳能放热氧化反应，分别生成氢气/一氧化碳；生成的氧化锌随后循环至第一步。文中还提供了基础科学概述、太阳能反应堆工程的技术进展以及生命周期和经济分析。
