Olafsson’s 2014 thesis, The Technical Potential of Renewable Natural Gas (RNG) in the United States, and the Economic Potential of Methanation-derived RNG in Texas, uses a thermodynamic balance to determine the total technical potential of RNG in the United States, as well as the future technical potential of methanation-derived RNG based on growth curves for renewable electricity. It argues that thermal gasification systems to process biomass are expected to become commercial in the next decade.
