摘　　要：有机液体储氢材料是理想的储氢介质。本文建立了以有机液体储氢材料为基础的氢储能系统的能效分析模型,并以乙基咔唑和二苄基甲苯两种有机液体储氢载体为算例,逐步计算了制氢、储氢和燃料电池等过程的能耗。研究结果表明,乙基咔唑能效优于二苄基甲苯,其储氢效率为84.17%、系统能效为47.58%。本研究所开发的框架可衡量基于有机液体储氢载体的氢储能系统的能效,并可用于筛选有机液体储氢载体。Liquid organic hydrogen carrier(LOHC)is a promising hydrogen storage medium.In this paper,an efficiencyanalysis model of liquid organic hydrogen carrier based hydrogen energy storage system is established,and the efficiencyof ethylcarbazole and dibenzyltoluene is investigated by calculating the energy consumption in the steps of hydrogenproduction,storage and fuel sell process.It is found that the hydrogen storage efficiency of the ethylcarbazole is84.17%and the system efficiency is47.58%,which are better than that of dibenzyltoluene.The framework developed in this studyis suitable for evaluating the efficiency of liquid organic hydrogen carrier based hydrogen energy storage system and canbe useful for screening candidate liquid organic hydrogen carrier.
