Viability analysis of direct current (DC) standalone hybrid photovoltaic (PV)/ hydrogen fuel cell (HFC) energy system: a techno-economic approach

摘要

The renewable energy sector in a developing country can play a vital role in socio-economic development. Renewable energy resources (RESs) such as photovoltaic (PV) energy system, wind energy system, hydrogen fuel cell (HFC) energy system, and so on should be properly utilized for renewable electricity generation for urban or rural populations. In this present work, the techno-economic analysis was carried out for the viability of a direct current (DC) based stand-alone hybrid PV/HFC energy system with hydrogen storage. The PV panel used for the study is monocrystalline silicon (mono-Si) with 13.5 efficiency and the study site considered for the analysis of the hybrid energy system is Madanapalle (13°33′N and 78°300′ E) in Andhra Pradesh, India. The connected electrical load to the hybrid PV/HFC system is assumed to be 14 kW.The optimal size obtained for the energy system is 80 kW PV system, 20 kWfuel cell, 50 kWelectrolyzer, andhydrogen tank of 20 kg. The cost of energy (COE) of the considered hybrid energy system is found to be 0.161 $/kWh.
