Hydrogen Production Using Solar Energy - Technical Analysis

This paper presents a case study concerning a plant for hydrogen production and storage, having a daily capacity of 100kg. The plant is located in Cluj-Napoca, Romania. It produces hydrogen by means of water electrolysis, while the energy is provided using solar energy. We performed the calculations for four different technical solutions used for the hydrogen production and storage plant, and also we considered three scenarios regarding the sub-systems of the hydrogen production and storage plant efficiency. The conclusion of this study is that one can maximize the conversion of solar radiation into chemical energy in the form of hydrogen by hybridizing the solar hydrogen production system, namely using both electrical energy as well as thermal energy in the form of steam.
