Abstract

This work intends to perform technical and 2E (economic & environmental) analysis for the proposed hybrid energy generating system for a part load at SRM IST at the Delhi-NCR campus, India. The investigation has been done for electricity generation and hydrogen production through renewable energy sources, mainly solar energy. It is in line with the Indian Government’s initiatives. The proposed hybrid system has to meet the electric load demand of 400 kWh/day with a peak load of 74.27 kW and hydrogen load demand of 10 kg/day with a peak demand of 1.86 kg/h. The analysis has been performed for both on-grid and off-grid conditions. As a result, optimum results have been obtained off-grid condition, with $0.408 per kWh cost of energy, $16.6 per kg cost of hydrogen, low O&M cost ($21,955 per year), a high renewable fraction (99.8%), and low greenhouse emissions (247 kg/year). In addition, sensitivity analysis has been performed between—(1) the solar PV array size & the number of battery strings, with NPC, renewable fraction & CO2 emissions as sensitivity variables, and (2) reformer capacity & hydrogen tank capacity, with NPC as sensitivity variable.

SRM IST德里NCR校区制氢混合能源发电系统的技术和2E分析

本工作旨在对印度德里NCR园区SRM IST的部分负荷拟议混合能源发电系统进行技术和2E（经济和环境）分析。已经对通过可再生能源（主要是太阳能）发电和制氢进行了调查。这符合印度政府的倡议。拟议的混合动力系统必须满足400千瓦时/天的电力负荷需求（峰值负荷为74.27千瓦）和10公斤/天的氢气负荷需求（高峰负荷为1.86公斤/小时）。已对并网和离网两种情况进行了分析。因此，在离网条件下获得了最佳结果，每千瓦时能源成本为0.408美元，每公斤氢气成本为16.6美元，运维成本低（每年21955美元），可再生能源比例高（99.8%），温室气体排放量低（每年247公斤）。此外，还对以下因素进行了敏感性分析：（1）太阳能光伏阵列尺寸和电池串数量，以NPC、可再生能源份额和二氧化碳排放量为敏感性变量；（2）重整器容量和氢罐容量，以NPC为敏感性变量。
