提出了一种具有CO2捕集功能的一体化氢电联产系统，并对其进行了技术经济评价。所提出的系统是一种替代的低成本清洁发电，同时为加工厂提供氢气。基线配置是根据文献设计的。在白杨Plus中对不同的情况进行了模拟，并进行了经济评价。热力学模型已验证对以前的出版物的结果。通过定义的技术经济环境指标，将具有不同产品份额的氢和电力的热电联产系统与CO2捕获和CO2排放的制氢装置进行了比较。对天然气价格和电价的输入参数进行了敏感性分析。模拟结果表明，在CO2捕集的研究案例中，热电联产系统的总效率略高于纯制氢系统（1 ~ 1.5%），而纯制氢系统的总效率仅为纯制氢系统的1 ~ 1.5%。经济评估结果表明，尽管氢成本随着热电联产而增加（5-8%），但CO2避免成本显著低于单独发电厂（低73-83%）。
An integrated hydrogen and power co-generation system with CO2capture has been proposed and evaluated techno-economically. The proposed system is an alternative low cost clean power generation while supplying hydrogen for process plants. The baseline configuration has been designed based on the literature. Different cases are simulated in Aspen Plus and are evaluated economically. Thermodynamic models have been validated against the results of previous publications. The co-generation system with different product shares of hydrogen and power has been compared with CO2captured and CO2-vented hydrogen plants by means of defined techno-economic-environmental indicators. Sensitivity analysis has been carried out for input parameters of natural gas and electricity prices. The simulation results demonstrate that in CO2capture studied cases, system total efficiency is slightly greater (1–1.5%) in co-generation cases than in hydrogen only production case with electricity importing from natural gas combined cycle and CO2venting. Economic evaluation results indicate that although hydrogen cost increases with power co-generation (5–8%), the CO2avoidance cost is significantly lower than in power plants alone (73–83% lower).
