Methanation by Sabatier Reaction¤
Introduction¤
Methanation is a thermochemical process of storing energy in a gaseous fuel chemical form: synthetic natural gas (SNG/CH4). This process is called Power-to-methane because it uses hydrogen produced from an electrolyzer working with electricity. Hydrogen is combined with carbon dioxide or with biogas, and the resulting mixture is converted into methane in methanation reactors, based on chemical methanation (Sabatier reaction).
The Sabatier reaction produces methane and water at elevated temperatures (300 °C) and pressures (30 bar). The resulting gas needs to be purified from impurities such as water and unconverted hydrogen to comply with the grid specifications. The main benefits of SNG is that it can be stored in, and transported through, the existing natural gas grid. CH4 has also a higher volumetric energy density
