基于“光-氢-电-热”协同的园区综合能源规划技术探讨 ——以内蒙古某项目为例
Technical discussion on integrated energy planning for parks based on “photovoltaic-hydrogen-electricity-heat” synergy:A case study of a project in Inner Mongolia
摘要：
中国建筑运行碳排放占全国碳排放的20%,建筑降碳任重道远。光伏已成为我国建筑行业降碳的重要方式之一,但由于光伏发电不稳定,导致光伏利用效率不佳,为了提高利用效率,通常搭配储能措施,如电化学储能、氢储能等。电化学储能相对简单,但一般仅能解决日间调蓄问题,氢储能则可以解决长时间尺度的储能问题。氢储能在建筑园区的应用较少,且氢能转换过程中余热较多,如何能实现“光-氢-电-热”协同供应是重中之重。本文以某园区零碳能源规划项目为例,通过对园区用户情况、能源特点进行分析,合理配置能源系统方案,最终实现了“光-氢-电-热”的协同供应,减碳效益较好,对于其他类似园区项目具有较好的参考价值。
Abstract：
Building operational carbon emissions account for 20% of China’s national total carbon emissions, indicating significant challenges in building decarbonization. Photovoltaic (PV) systems have become a key carbon reduction solution in China’s construction sector. However, the instability of PV power generation limits utilization efficiency, often requiring integration with energy storage measures such as electrochemical storage and hydrogen storage. While the electrochemical storage addresses short-term (daily) regulation, and the hydrogen storage enables long-term energy management. Nevertheless, hydrogen storage applications in building parks remain limited, and its conversion process generates substantial waste heat. Achieving coordinated “PV-hydrogen-electricity-heat” supply is therefore critical. This study examines a zero-carbon energy planning project in a park. Through analysis of user profiles and energy characteristics, an optimized integrated energy system is developed. The system achieves effective coordination of “PV-hydrogen-electricity-heat” supply, demonstrating notable carbon reduction benefits. The methodology provides a valuable reference for similar park projects.
