| Summary: |
Power-to-Gas (PtG) processes transform exceeding renewable power in a storable gas such as methane, also called Synthetic Natural Gas (SNG), and for that they also require a carbon source like CO2. Carbon dioxide may be available from processes such as coal or biomass gasification (for syngas production), biomass anaerobic fermentation (for biogas production), or in flue gas streams obtained in several industrial processes (e.g. coal and natural gas power plants, refineries, cement industry, etc.). The CO2 purification requirements, for its later use in the methanation reaction, may differ
substantially depending on the carbon source considered, which has a direct influence on PtG process configuration and flexibility. Power2Methane project focuses on the study and development of a Carbon Capture and Utilization (CCU) technology able to, simultaneously, remove CO2 from flue gas or biogas upgrading streams, and further convert it to methane in a hybrid and cyclic sorption-reaction unit. |
