Techno‐economic feasibility of hydrogen based electric vehicle charging station: A case study.

Summary: Delhi has been experiencing a dramatic surge in pollution levels, especially in the past decade. Renewable energy sources emit negligible carbon pollutants compared to conventional energy sources. However, they are fundamentally intermittent, necessitating a robust storage system. In recent times, hybrid systems have proven to be breakthrough solutions for mitigating electrical energy shortages while also enhancing overall system dependability. This study focuses on hydrogen energy storage which can help overcome variable output power issues for an electric vehicle charging station in Karampura, Delhi. The framework is proposed for three vehicles charging simultaneously, all the while at the charging station, with normal energy utilization of 2100 kWh/day. The most optimum system is found by simulating results from three different combinations (namely photovoltaic [PV]‐Hydrogen, Wind‐Hydrogen, and PV‐Wind‐Hydrogen) using HOMER software. The Levelized cost for the Hybrid combination is most viable, whereas the Wind system costs 7.19% more and the PV combination costs 12.12% higher. In a similar manner, the net present cost (NPC) of a solar PV system and a wind turbine system is $1.80 million and $1.63 million, respectively, whereas the NPC of a hybrid system is $1.52 million. The cost of operating a PV solar system is $79 767, a wind turbine system is $46 078, and a hybrid system is $35 926. These findings suggest that a hydrogen‐based hybrid renewable energy system is an economically feasible combination. [ABSTRACT FROM AUTHOR]
