Design of modular electrolysis and modular high-efficiency fuel cell systems for green hydrogen production and power generation with low emission of carbon dioxide

Abstract

This study presents a system model of the process for converting water and sunlight into green hydrogen which is then used to generate electrical energy with low emission of carbon dioxide. The proposed system model incorporates modular electrolysis cells for green hydrogen production and modular high-efficiency fuel cells for power generation. The results show that modular electrolysis cells can produce hydrogen at 149 tons/day. The produced hydrogen can be used to generate 100 MW of electricity. The carbon dioxide emission index is 0.206 tons/MWh which is lower than conventional technologies. The proposed systems have excellent performance in terms of efficiency and environmental pollution reduction. The results in this paper can be used in the process design for green hydrogen production and power generation.
