Carbon footprint of synthetic natural gas through biogas catalytic methanation

The carbon footprint of synthetic natural gas production from biogas catalytic methanation was determined. The material and energy data inputs required to produce 1 kWh of synthetic natural gas were experimentally collected from a pilot plant operating in a waste water treatment plant as a relevant...
