Abstract This paper proposes a novel integrated system for hydrogen and natural gas blending system for a selected residential application. In the current system, hydrogen is generated via an alkaline water electrolyzer unit, and the electricity required for the electrolyzer is supplied from renewable sources, i.e., solar PV panels and wind turbines. The remaining electricity is supplied to the building where the system will be built. The whole system is evaluated using the Aspen Plus software and Engineering Equation Solver (EES). The hydrogen fraction is increased by volume from 0% to 20% in the blend while the natural gas volume fraction is decreased from 100% to 80%. With the increase of hydrogen injection, carbon dioxide emissions from the combustion unit are reduced. According to the performance assessment, the highest values for the overall energy and exergy efficiencies are 67.3% and 53.2%, respectively in March and their lowest values are 58.4% and 44.2%, respectively in December.

开发集成氢气和天然气子系统的可再生能源系统，实现清洁燃烧

摘要 本文提出了一种用于选定住宅应用的氢气和天然气混合系统的新型集成系统。在目前的系统中，氢气是通过碱性水电解槽装置产生的，电解槽所需的电力来自可再生能源，即太阳能光伏板和风力涡轮机。剩余的电力供应给将要建造系统的建筑物。整个系统使用 Aspen Plus 软件和工程方程求解器 (EES) 进行评估。在混合物中，氢气的体积分数从 0% 增加到 20%，而天然气的体积分数从 100% 减少到 80%。随着氢气注入量的增加，燃烧装置的二氧化碳排放量减少。根据绩效考核，
