Modulization of hydrogen storage in ammonia’s form via photovoltaic system

Abstract

Nowadays researchers are tending to use ammonia produced from renewable energy as a way to transport and store clean hydrogen, due to its advantages such as high density of hydrogen by weight and safety. In this work, we have used a system that consists of HaberBosch

to produce ammonia and a proton exchange membrane electrolysis for hydrogen production in addition to a photovoltaic system for energy supply. and we have used MATLAB Simulink for modulization to compute the amount of hydrogen and nitrogen and the energy needed for the system, and CHEMCAD to compare the obtainedamount of hydrogen and nitrogen to that obtained from MATLAB Simulink. The results of this study indicate that for 1000(ton/h) of ammonia we obtained 411.31(ton/h) of nitrogen and 177.56(ton/h) of hydrogen and the amount of water that the proton exchange membrane electrolysis needs is 1.9531e+06(ton/h) in addition to the energy required by it 7.8915e+06(Gwh) and total energy output from the photovoltaic field 8.6261e+06 (Gwh) furthermore, the efficiency of electrolysis, when it increases, does effect the energy of electrolysis and total energy output from the photovoltaic field by decreasing it. we found out that Adrar is the best location for installing photovoltaic panels due to its smallest peak power peak power= 1135013.16 KW p .
