Comparison of SNG (Synthetic Natural Gas) Production Pathways for the Storage of Renewable Energy - a German Case Study

S. Fendt, F.G. Albrecht, M. Gaderer & H. Spliethoff
In the course of energy system transformation towards sustainability, SNG concepts using the existing natural gas grid as storage system for renewable energy have significantly gained importance in recent years. To evaluate the performance of SNG technology based on renewable energies, the three most advanced and relevant concepts called Biogas-to-SNG (biochemical), Syngas-to-SNG (thermochemical) and Power-to-SNG (electrochemical) are analyzed and compared in terms of development status, efficiencies, technical potential, production costs and ecological impacts. Finally, a...
