Biomethane injection into natural gas networks

Abstract: 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. This chapter briefly introduces: the legal framework and technical standards of biomethane feed-in into the gas network in Germany; 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. The chapter also looks at one of the most challenging aspects of biomethane feed-in – costs and energy efficiency – and outlines several options for improvement.
