The largest anthropogenic source of carbon dioxide emissions is the global energy system, which means transforming the global energy system is one of the most significant ways to reduce greenhouse gas emissions and mitigate climate change. Buildings play a critical role in our transition to a lower-carbon future, accounting for approximately 47% of global energy consumption and about 25% of global greenhouse gas emissions. Renewable hydrogen represents one of the most environmentally friendly options for energy generation. This study presents an energetic, economic, and environmental impact of a self-sufficient system for energy production from renewable energy sources in buildings. To achieve this objective, a hydrogen-based generation system was selected to meet all the electrical requirements of tertiary building in Algeria throughout the year. The results indicate that the hybrid renewable energy system can avoid the emission of approximately 1056 tons of carbon dioxide per year. Furthermore, the payback period is 7 years. These results clearly demonstrate that the integration of hydrogen energy in buildings is the optimal choice for environmental sustainability.
人为二氧化碳排放的最大来源是全球能源系统，这意味着要减少温室气体排放和缓解气候变化，改造全球能源系统是最有效的方法之一。建筑在我们向低碳未来的过渡中起着至关重要的作用，其能源消耗约占全球的 47%，温室气体排放量约占全球的 25%。可再生氢是最环保的能源发电选项之一。本研究展示了建筑中可再生能源自给自足的能源生产系统在能源生产方面的能源、经济和环境影响。为了实现这一目标，选择了基于氢的发电系统来满足阿尔及利亚三级建筑全年的所有电力需求。结果表明，混合可再生能源系统每年可避免约 1056 吨二氧化碳的排放。此外，投资回收期为 7 年。这些结果清楚地表明，将氢能融入建筑是实现环境可持续性的最佳选择。
