Green hydrogen can be the transitional solution required to reduce anthropogenic emissions and enhance energy independency from fossil fuel. To improve green hydrogen adoption, a cluster-based infrastructure, called a hydrogen hub, is devised taking into account the demand-supply interplay coupled with transport ease. In this paper, we have identified sites across states that are conducive for hydrogen hubs. It involves a multicriteria decision-making (MCDM) framework deployed to assign priorities within competing set of criteria. A comprehensive analytical hierarchy process (AHP) is used to rank criteria that are connected to establish a functioning hydrogen hub. These criteria include, but not limited to, proximity to refineries, fertilizer plants, substations, chlor-alkali units, steel manufacturing plants, water availability, access to gas pipelines, railway line access, and finally distance to highways. Our analyses indicate that proximity to refineries and fertilizers scored higher (scores directly proportional to importance) while railway line access scored the least. These prioritised scores are used to spatially locate sites using geographical information system. In a total of thirteen states identified, Gujarat had the largest parcel of most suitable land for setting up hydrogen hub followed by Maharashtra and Andhra Pradesh. For India to set up a functioning hydrogen economy and achieve green hydrogen goals, it is important to identify states that can drive the agenda forward. This paper illustrates a way (amongst many available ways) to identify states based on their strength and capability to fulfil the national goal of 5 million tons of green hydrogen by 2030.

印度的绿色氢中心：跨邦选址的一阶层次分析法

绿色氢可以成为减少人为排放和增强对化石燃料的能源独立性所需的过渡解决方案。为了提高绿色氢的采用，设计了一个基于集群的基础设施，称为氢中心，考虑到供需相互作用以及运输便利性。在本文中，我们确定了各州有利于氢中心的地点。它涉及一个多标准决策 (MCDM) 框架，用于在一组竞争标准内分配优先级。综合层次分析法 (AHP) 用于对连接建立正常运作的氢中心的标准进行排名。这些标准包括但不限于靠近炼油厂、化肥厂、变电站、氯碱装置、钢铁制造厂、水的可用性、天然气管道的可达性、铁路线的可达性以及最后到高速公路的距离。我们的分析表明，靠近炼油厂和化肥厂的得分较高（得分与重要性成正比），而靠近铁路线的得分最低。这些优先分数用于使用地理信息系统对站点进行空间定位。在总共确定的十三个邦中，古吉拉特邦拥有最大的最适合建立氢中心的土地，其次是马哈拉施特拉邦和安得拉邦。印度要建立有效的氢经济并实现绿色氢目标，重要的是要确定能够推动议程向前发展的国家。本文阐述了一种根据各国实现 2030 年 500 万吨绿色氢国家目标的实力和能力来识别各国的方法（在许多可用方法中）。
