Techno-economic analysis of PV/H 2 systems

Abstract

Keywords:Renewable energy Photovoltaic hybrid system Fuel cell Electrolyzer Energy cost a b s t r a c tThe purpose of this paper is to analyze the costs of grid-connected PV/H 2 systems sized to meet a setpoint power using ORIENTE ® software. The aim is to determine optimal component sizes to minimize cost of injection-to-grid.We study the case of guaranteed PV production where the PV array is coupled to a hydrogen chain to inject a constant setpoint power into the grid from 8am to 5pm (local time) all year long without failure (100% satisfaction level). We studied 4 setpoint powers: 100, 200, 300 and 400 kW.The results show that regardless of setpoint power, the optimum system design fits the ratios: installed PV power-to-setpoint power ¼ 2.4e2.5; nominal electrolyzer power-tosetpoint power ¼ 0.72e0.75; nominal fuel cell power-to-setpoint power ¼ 1. We also found that the capacity of the H 2 tanks corresponds to around 48e50 days of off-grid power (number of days where setpoint power comes exclusively from the fuel cells).

“…The combination of two to form a solar-FC hybrid energy system is a reliable and cost-competitive solution. 4 Numerous economic analyses [5][6][7][8] have been reported by considering on-grid, PV-FC hybrid energy system to cater the institution load demand and household applications, further which have been proven to be a costeffective and reliable option for renewable power generation. The sizing and optimization of grid-connected FC and solar PV generation to minimize the levelized cost of electricity (LCOE) and maximize efficiency, respectively, has emerged as a challenging task.…”
