How to store energy in biogas power generation

Many biogas systems incorporate energy storage solutions such as compressed natural gas (CNG) or liquefied natural gas (LNG) technologies. These methods allow biogas to be stored and transported efficiently, maximizing its use in various applications. Energy yield varies widely, depending on feedstock quality and composition, with values typically between 20 to 30 MJ/m³. In Germany and other industrialised countries, power generation is the main purpose of biogas plants; conversion of biogas to electricity has become a standard technology. At the heart of this process are biogas digesters—airtight containers where microorganisms break down food.
