Recently, the management of water and wastewater is gaining attention worldwide as a way of conserving the natural resources on the planet. The traditional wastewater treatment in Oman is such that the treated effluent produced is only reused for unfeasible purposes such as landscape irrigation, cooling, or disposed of in the sea. Introducing more progressive reuse applications can result in achieving a circular economy by considering treated effluent as a source of producing new products. Accordingly, wastewater treatment plants can provide feedstock for green hydrogen production processes. The involvement of the wastewater industry in the green pathway of production scores major points in achieving decarbonization. In this paper, the technical and economic feasibility of green hydrogen production in Oman was carried out using a new technique that would help explore the benefits of the treated effluent from wastewater treatment in Oman. The feasibility study was conducted using the Al Ansab sewage treatment plant in the governate of Muscat in Wilayat (region), Bousher. The results have shown that the revenue from Al Ansab STP in a conventional case is 7.02 million OMR/year, while sustainable alternatives to produce hydrogen from the Proton Exchange Membrane (PEM) electrolyzer system for two cases with capacities of 1,500 kg H/day and 50,000 kg H/day, would produce revenue of 8.30 million OMR/year and 49.73 million OMR/year, respectively.
最近，作为保护地球上自然资源的一种方式，水和废水管理在全球范围内受到关注。阿曼传统的废水处理方式是，处理后的出水仅用于景观灌溉、冷却等不可行的用途，或排入大海。引入更先进的回用应用可以通过将处理后的出水视为生产新产品的来源来实现循环经济。因此，废水处理厂可以为绿色制氢生产过程提供原料。废水行业参与绿色生产途径在实现脱碳方面得分很高。本文利用一种新技术对阿曼绿色制氢的技术和经济可行性进行了研究，该技术将有助于探索阿曼废水处理后出水的益处。可行性研究使用了马斯喀特省布舍尔地区的安萨卜污水处理厂。结果表明，在传统情况下，安萨卜污水处理厂的年收入为702万里亚尔/年，而采用质子交换膜（PEM）电解槽系统制氢的两种可持续替代方案，产能分别为1500千克氢气/天和50000千克氢气/天，年收入分别为830万里亚尔/年和4973万里亚尔/年。
