Biomethane is a flexible and easily storable fuel that can be used wherever natural gas is used without the need to change any settings on equipment designed to use natural gas. In regions where a natural gas grid already exists, there is a ready-made system for the distribution of biomethane. In chapter 16 of the Biogas Handbook, Ecologic Institute's Dr. Wolfgang Urban briefly introduces the legal framework and technical standards of biomethane feed-in to the German gas network. The chapter furthermore describes the different subsidy schemes and reliefs to encourage biomethane production or utilization; and the different available options for biomethane feed-in and feed-in facilities.
