Efficiency Analysis of Synthetic Methane Production in Power-to-Gas Process Employing Solid Oxide Electrolyser

Abstract

The power-to-gas technology is considered to provide the means of storing surplus renewable energy in the form of synthetic natural gas. The study analyses the P2G system with respect to the three main components i.e. electrolysers (especially solid oxide electrolysers that have a higher operating temperature), the methanation reactor and the synthetic methane injection system. Efficiency of the individual components is evaluated with three different configurations employing heat recovery at various sections of the P2G system. The model has been studied in the ANSYS environment. The configurations are finally evaluated for an optimized solution as regards the efficiency of the entire system and the quality of the produced synthetic.
