基于CLHG-SOFC的综合能源系统低碳经济优化调度
Low-carbon Economic Optimization Scheduling of Integrated Energy Systems Based on CLHG-SOFC
为推动“零碳中国”倡议行动,提高能源利用效率,在综合能源系统中引入化学链制氢(chemical looping hydrogen generation, CLHG)技术与固体氧化物燃料电池(solid oxide fuel cell, SOFC),实现在供能的同时分离出纯净的二氧化碳。首先,为避免SOFC使用碳氢燃料所产生的积碳问题,采用CLHG为SOFC提供氢气,并构建CLHG-SOFC联合循环系统及综合能源系统框架。其次,构建基于CLHG-SOFC的综合能源系统优化调度模型,并将传统甲烷水蒸汽重整(steam methane reforming, SMR)制氢和SMR使用甲基二乙醇胺吸收技术捕捉二氧化碳制氢分别与SOFC结合进行对比分析。最后,进行SOFC操作温度及操作压力对系统运行成本和碳排放的敏感性分析。分析结果表明:CLHG与SOFC相结合在制氢、减少碳排放和系统运行经济性方面具有显著优势。
In order to promote the "Zero Carbon China" initiative and enhance energy utilization efficiency, chemical looping hydrogen generation (CLHG) technology and solid oxide fuel cells (SOFC) were introduced into integrated energy systems. The goal was to simultaneously supply energy while separating pure carbon dioxide. Firstly, to avoid the carbon deposition issue caused by using hydrocarbon fuels in SOFCs, CLHG was employed to supply hydrogen to the SOFC, thereby constructing a CLHG-SOFC combined cycle system and an integrated energy system framework. Secondly, an optimization scheduling model for the integrated energy system based on CLHG-SOFC was developed. A comparison was then made between traditional steam methane reforming (SMR) hydrogen production and SMR combined with methyl diethanolamine absorption technology for CO2 capture, both integrated with SOFC. Finally, sensitivity analysis was conducted to assess the impact of SOFC operating temperature and pressure on system operation costs and carbon emissions. The results indicate that the combination of CLHG and SOFC has significant advantages in terms of hydrogen production, carbon emission reduction, and system operational economics.
