As a result of the accelerated turnaround in energy policy and Germany's complete nuclear phase-out by the end of 2022 there is a need for a radical transformation of the energy supply. In the conflicting areas of renewable energies expansion, network infrastructure with limited feed-in capacity, focussed centres of energy generation and fluctuations in demand, the discussion around implementation is controversial. A promising solution is the power-to-gas concept with which surplus electricity from wind energy can be transformed into synthetic natural gas. The combination of this process with biogas technology offers great potential for efficiency improvement. The upgrading of raw biogas to biomethane by pressureless amine scrubbing involves relevant synergy effects that can be exploited in terms of heat and carbon dioxide. [ABSTRACT FROM AUTHOR]
