Descripción
Power to Synthetic-Natural-Gas (SNG) technology consists of two main steps: water electrolysis and methanation; the primary energy input is usually surplus power from renewable electricity sources, while the electrolytic hydrogen (H2) and carbon oxides from different COx sources are converted into methane to be fed in the natural gas grid. To compare technologies, the main parameters analyzed in this work are the achievable quality of gas products, the reactor volumes needed to reach the required production and gas quality, as well as the complexity of process setup. It is concluded that Power-to-SNG technologies that use methane rich streams for CO2 hydrogenation are favorable in terms of H2 requirement, reactor size, process simplicity and biogas upgrading, as far as these resources are available; e.g. using a typical biogas rich composition of 60% CH4, the required inputs are 0.96 kmol of biogas, 1.54 kmol of H2 and 0.26 m3 of reactors (two adiabatic beds with R/F = 0.695) per kmol/min of pipeline quality dry gas product (95% CH4), which means 60% hydrogen saving, near 62% reduction of reactor throughput (Fo) and less than 26% reaction volumes when compared to the methanation process that utilizes pure CO2.
