Abstract—Solar PV and wind turbine technologies are the prime sources of renewable energy and have rapidly increased their share in the total electricity production in the recent years. However, these technologies are highly dependent on nature and makes them an unreliable source of energy from an end-point perspective. Power to Gas (PtG) technology resolves this issue and provides an opportunity to convert these intermittent sources of energy into a more reliable one. With the processes of electrochemistry combined with methanogenesis PtG technology is able to provide a more reliable source of energy in the form gases (hydrogen or methane), that can be both stored and transported. This article discusses various electrochemical parameters such as voltage, current, electrode material, pH and temperature using cyclic voltammetry technique in order to select the best electrode material. Three electrode materials (platinized titanium mesh, carbon felt and graphite rod) are compared with each other for their electrochemical performances at 4 different pH and 6 different temperatures. The results show that carbon felt electrode material is the most efficient and inexpensive material for further research in the field of bioelectrochemical wastewater treatment.
