Abstract

Solar PV and wind turbine technologies are theprime sources of renewable energy and have rapidly increasedtheir share in the total electricity production in the recent years.However, these technologies are highly dependent on nature andmakes them an unreliable source of energy from an end-pointperspective. Power to Gas (PtG) technology resolves this issueand provides an opportunity to convert these intermittentsources of energy into a more reliable one. With the processes ofelectrochemistry combined with methanogenesis PtG technologyis able to provide a more reliable source of energy in the formgases (hydrogen or methane), that can be both stored andtransported. This article discusses various electrochemicalparameters such as voltage, current, electrode material, pH andtemperature using cyclic voltammetry technique in order toselect the best electrode material. Three electrode materials(platinized titanium mesh, carbon felt and graphite rod) arecompared with each other for their electrochemicalperformances at 4 different pH and 6 different temperatures.The results show that carbon felt electrode material is the mostefficient and inexpensive material for further research in thefield of bioelectrochemical wastewater treatment.
