太阳能热化学储能技术关键材料研究现状
Research status of key materials for solar thermochemical energy storage technology
摘要
Abstract
The recent advancements in key materials including reactants and catalysts employed in solid-gas,gas-gas,and liquid-gas solar thermochemical energy storage(TCES)systems are reviewed.The thermochemical properties of reactants such as carbonates,hydroxides,metal hydrides,metal oxides,organics,and ammonia are examined.The research status of the modification of these reactants,new material development,and catalyst improvement are also discussed.At present,the reactant materials suitable for solar TCES exhibit various deficiencies in terms of cyclic stability,reactivity,conversion rate,energy storage density,cost or safety,which hinder the commercial viability of solar TCES technology.To further enhance the maturity of solar TCES technology,it is imperative to develop advanced composite materials on the basis of known thermochemical reaction systems,improve novel efficient catalysts,and broaden demonstration application scenarios and scales in the future.The key materials should endow TCES systems with high energy storage density,more robust cyclic stability,and rapider reaction kinetics.It is preferred that they are readily available,non-corrosive,and non-toxic and more cost-effective.关键词
