Abstract

Dense ceramic membranes with H+ or O2− conductivity have been widely used for fuel production through electro-hydrogenation/dehydrogenation or electro-oxygenation/deoxygenation. Electrochemical conversion processes demonstrate advantages over conventional redox reaction processes in terms of capital cost, energy savings, process intensification and product selectivity. Intermittent renewable power (e.g., solar and wind power) can be used to drive electrochemical processes so that renewable energy is stored in fuels as energy carriers, including hydrogen, ammonia, syngas, methane and ethylene. This review summarizes the pathways to store renewable energy via ion-conducting membrane reactors and discusses the commercialization progress and prospects of these energy technologies.

用于可再生能源技术的离子传导陶瓷膜
具有H+或O2−导电性的致密陶瓷膜已广泛用于通过电加氢/脱氢或电氧化/脱氧生产燃料。电化学转化工艺在资本成本、能源节约、工艺强化和产品选择性方面优于传统的氧化还原反应工艺。间歇性可再生能源(如太阳能和风能)可用于驱动电化学过程,从而将可再生能源作为能源载体储存在燃料中,包括氢气、氨、合成气、甲烷和乙烯。本文综述了通过离子传导膜反应器储存可再生能源的途径,并讨论了这些能源技术的商业化进展和前景。
