It is understood that biogas and natural gas have similar properties, with methane as the main component, and belong to the category of clean gas energy. In short, biogas power generation refers to the use of biogas generated by anaerobic fermentation treatment on engines, and the installation of a comprehensive power generation device to generate electricity and heat energy. This form of power generation has the characteristics of efficiency creation, energy conservation, safety, and environmental protection, and is a widely distributed and cost-effective distributed energy source. It is reported that biogas power generation has been valued and promoted in developed countries, and currently biomass energy grid connection accounts for up to 10% of the total energy in some Western European countries.
