Biological Methanation Demonstration Plant in Allendorf, Germany: An Upgrading Facility for Biogas
This IEA Bioenergy Task 37 case study concerns upgrading biogas to biomethane using hydrogen in Germany. In theory this system can store surplus electricity that would have been curtailed (producing H2), captures CO2 that would have been emitted (from biogas) and replaces traditional biogas upgrading.
