Effective Utilization of Solar Energy for the Production of Green Hydrogen from Photovoltaic Powered Electrolyzer
Source abstract
Abstract
Abstract Hydrogen is considered as the fuel of the future. But currently, efficient, clean, and cheap hydrogen production is one of the challenging tasks. In this article, a clean and cheap hydrogen gas is produced through an alkaline-based water electrolyzer powered by a photovoltaic (PV) module, 27-wt. % sodium hydroxide is used as an electrolyte, and the electrolyzer is constructed by using stainless steel anode and nickel-platted stainless-steel cathode. The radiation on a PV module and current from the PV module is measured, and it is found that maximum radiation and current is possible in May. The ideal volume of hydrogen gas is calculated using Faraday’s, and the actual volume produced is also measured. It is found that the volume of hydrogen gas produced is dependent on the solar flux available. The maximum amount of 100 L of hydrogen gas produced is found to be in May, whereas the minimum is witnessed in August. The effectiveness of hydrogen gas is also calculated to determine the losses in the electrolyzer. The electrolyzer is found to be 15 % effective. Future directions of the research are also provided to improve the effectiveness of the electrolyzer.
