Today, biogas is generally used directly at the place where it is produced in a cogeneration plant. However, biogas can also be refined to natural gas quality and fed directly into the natural gas network. This way, the refined gas can be transported flexibly and economically to the site of use. Here, the gas can be used to generate electricity and heat with particular efficiency, or it can be used as fuel. PlanET Biogastechnik has access to all of the leading methods of biogas refinement over a pan-European technology network.
