Solar energy is potentially the most abundant renewable energy resource available to us and hydrogen production from solar energy is considered to be the ultimate solution for sustainable energy. The various methods for utilizing solar energy for hydrogen production are examined and both their advantages and disadvantages are compared.
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. 1876-6102 © 2017 The Authors. Published by Elsevier Ltd.
The most common method of solar-based hydrogen production utilizes photovoltaic (PV) cells in combination with water electrolysis. In this system, PV cells are used to create electrical energy. An electrolyzer passes this electric current through water, causing the water molecules to separate into hydrogen and oxygen gases.
The combined system produces 29,200 kg/year of H 2 with a levelized cost of hydrogen production (LCOP) of $8.94 per kg of H 2. Maximum energy destruction was reported in the reactor, followed by the solar collector, which lays a strong foundation for optimizing the collector system to operate more efficiently.
MIT engineers designed a system that can efficiently produce “solar thermochemical hydrogen.” It harnesses the sun’s heat to split water and generate hydrogen — a clean fuel that emits no greenhouse gas emissions.
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.
