The reliable and sustainable energy source for supplying energy demand of rural health clinic centers (RHCC) is very important especially in Coronavirus Disease 2019 (COVID-19) epidemic. However, diesel generator due to the fuel supply and environmental challenges can’t be a sustainable source. In this regard a standalone energy system based on solar with hydrogen storage/fuel cell system is proposed to solve this issue. In the present study, five regions with different climatic conditions in Iran are considered and the layout are evaluated for the first time in RHCC with a load demand of about 10 kWh/day. HOMER software is used to optimize the size of the equipment. The results showed the capacity factor (CF) of photovoltaic panels is about 17.4–20.4%, while the CF of electrolyzers is 17–25%. The CF of fuel cell remains similar at about 36–37%. The net present value of the systems ranges 22,000–27,000$ and the levelized cost of electricity ranges 0.28–0.34 $/kWh, with the lowest (highest) values in Kerman(Gylan). The proposed system reduced the consumption of approximately 1,830 L of diesel, resulting in significant environmental benefits. The hybrid renewable energy system combining solar and hydrogen storage can be considered as sustainable solution in RHCC in Iran.

在伊朗农村医疗中心建设集成光伏与储氢作为可持续解决方案


可靠且可持续的能源对于满足农村卫生诊所中心 (RHCC) 的能源需求非常重要，尤其是在 2019 年冠状病毒病 (COVID-19) 流行期间。然而，由于燃料供应和环境挑战，柴油发电机不能成为可持续的能源。在这方面，提出了一种基于太阳能和氢存储/燃料电池系统的独立能源系统来解决这个问题。在本研究中，考虑了伊朗五个不同气候条件的地区，并首次在负荷需求约为10千瓦时/天的RHCC中进行布局评估。 HOMER软件用于优化设备的尺寸。结果显示，光伏板的容量因子（CF）约为17.4-20.4%，而电解槽的CF为17-25%。燃料电池的CF保持相似，约为36-37%。系统的净现值范围为 22,000–27,000 美元，平均电力成本范围为 0.28–0.34 美元/千瓦时，其中最低（最高）值位于克尔曼（吉兰）。拟议的系统减少了约 1,830 升柴油的消耗，带来了显着的环境效益。结合太阳能和储氢的混合可再生能源系统可以被视为伊朗 RHCC 的可持续解决方案。
