Biogenic methane vs fossil methane
WebThe methane content of biogas typically ranges from 45% to 75% by volume, with most of the remainder being CO 2. This variation means that the energy content of biogas can … WebFigure 1: Biogenic 'short cycle' carbon vs fossil carbon. Biogenic methane. Like CO 2, CH 4 can be biogenic or fossil in origin. There are many natural sources of fossil CH 4 such as marine and terrestrial seepages, geothermal vents and mud volcanoes formed over thousands to millions of years.
