HYDROGEN PRODUCTION FROM SOLAR TRACKER WITH MPPT TECHNIQUE IN SEAWATER ELECTROLYSIS

Abstract

The future fuel hydrogen is being produced by doing electrolysis in seawater. The power for electrolysis is given by using solar panel. The electrode used for seawater electrolysis is being coated with various layers. The layers used are Nickel iron hydroxide and Nickel sulfide layers. These layers will protect the electrode from corrosion. The maximum power point tracking technique is deployed in order to utilize the most power from the photovoltaic panel. This is done with the help of light dependent resistors or photo resistors, micro controller arduino and servo motor of 6V. The switching operation was done along with Node MCU and an ESP8266 Wi-Fi module. The objective of this project is to produce hydrogen for industrial use. The 12V solar panel is used for providing power for electrolysis process. One form of energy is converted to another form efficiently without loss. The energy from the Sun is converted to hydrogen for industrial use or for running vehicles. The current density should be high for such usage. Several tests are performed to show the variations in hydrogen production, with and without layer coating, with and without solar tracking technique. The tests include variations in solar irradiance, variations in anode, stability test and efficiency chart. The variations in solar intensity radiation were measured with the help of pyranometer.
