While Afghanistan's power sector is almost completely dependent on fossil fuels, it still cannot meet the rising power demand of this country. Deploying a combination of renewable energy systems with hydrogen production as the excess energy storage mechanism could be a sustainable long-term approach for addressing some of the energy problems of Afghanistan. Since Badakhshan is known to have a higher average wind speed than any other Afghan province, in this study, a technical, economic, and carbon footprint assessment was performed to investigate the potential for wind power and hydrogen production in this province. Wind data of four stations in Badakhshan were used for technical assessment for three heights of 10, 30, and 40 m using the Weibull probability distribution function. This technical assessment was expanded by estimating the energy pattern factor, probability of wind speeds greater than 5 m/s, wind power density, annual power output, and annual hydrogen output. This was followed by an economic assessment, which involved computing the Leveled Cost Of Energy (LCOE), the Leveled Cost Of Hydrogen (LCOH), and the payback period, and finally an carbon footprint assessment, which involved estimating the consequent CO2 reduction in two scenarios. The assessments were performed for 22 turbines manufactured by reputable companies with capacities ranging from 600 kW to 2.3 MW. The results showed that the entire Badakhshan province, and especially Qal'eh-ye Panjeh and Fayazabad, have excellent potentials in terms of wind energy that can be harvested for wind power and hydrogen production. Also, wind power generation in this province will be highly cost-effective, as the produced electricity will cost about one-third of the price of electricity supplied by the government. For better evaluation, the GIS maps of wind power and hydrogen outputs were prepared using the IDW method. These maps showed that the eastern and northeastern parts of Badakhshan province have higher wind power-hydrogen production potentials. The results of ranking the stations with SWARA-EDAS hybrid MCDM methods showed that Qal'eh-ye Panjeh station was the best location to produce hydrogen from wind energy.

技术、经济、碳足迹评估以及利用风能生产氢气的优先站点:案例研究

尽管阿富汗的电力部门几乎完全依赖化石燃料,但仍无法满足该国不断增长的电力需求。部署可再生能源系统与氢气生产的组合作为过剩能源存储机制可能是解决阿富汗一些能源问题的可持续长期方法。由于已知巴达赫尚的平均风速高于阿富汗任何其他省份,因此在本研究中,进行了技术、经济和碳足迹评估,以调查该省风力发电和制氢的潜力。采用威布尔概率分布函数,利用巴达赫尚4个台站的风数据对10、30、40 m三个高度进行技术评估。该技术评估通过估算能量模式因子、风速大于 5 m/s 的概率、风功率密度、年发电量和年氢气产量进行了扩展。随后是经济评估,其中涉及计算能源平衡成本 (LCOE)、氢气平衡成本 (LCOH) 和投资回收期,最后是碳足迹评估,其中包括估计随之而来的 CO2减少两种情况。评估是针对由信誉良好的公司制造的 22 台涡轮机进行的,容量从 600 kW 到 2.3 MW。结果表明,整个巴达赫尚省,尤其是Qal'eh-ye Panjeh 和Fayazabad,在风能方面具有极好的潜力,可用于风能和制氢。此外,该省的风力发电将具有很高的成本效益,产生的电力成本约为政府供电价格的三分之一。为了更好地进行评估,使用 IDW 方法准备了风电和氢气输出的 GIS 地图。这些地图表明,巴达赫尚省东部和东北部地区具有较高的风电制氢潜力。
