Overview and evaluation of Biogas, Biomethane, and Purification Methods
Summary:
Biogas and biomethane are renewable gases that should be strongly considered to accelerate decarbonization and reduce greenhouse gas emissions in many sectors. In addition, biomethane is important to provide renewable and more economical energy to consumers using the existing gas infrastructure. Moreover, biomethane can be easily stored and can be used as a balancer for intermittent renewable energy sources such as solar and wind. The EU considers bio-CNG (compressed), bio-LNG (liquefied) fuels to be an effective method in reducing emissions. Therefore, Europe leads the world in biogas and biomethane production. In this study, evaluations and general views were made about the definition of biogas and biomethane, production amounts in the world and purification methods (treatment) of biogas. The main purpose of the current study is to emphasize that biogas provides an important solution for decarbonization and that its usage areas can be expanded by purifying it as biomethane.
