Autogenerative high-pressure fermentation (AHPD) is a biogas production technique that operates under elevated gas pressure. This pressure is naturally generated by the bacteria and archaea through the gases they release. First described by R. Lindeboom of University of Wageningen (WUR) in 2011, a batch reactor was pressurized to 58 bar, yielding a methane concentration of 96% in the resulting biogas. This method is also commonly referred to as High Pressure Anaerobic Digestion (HPAD) in scientific literature. AHPD leverages the higher solubility of carbon dioxide (CO2) at 0.031 mol/L/bar compared to methane (CH4) at 0.0016 mol/L/bar. This difference allows more CO2 to dissolve in the digestate, while hydrogen sulfide (H2S) also dissolves more efficiently under pressure. The result is biogas with a higher methane content, which requires less upgrading to meet natural gas standards, ultimately reducing processing costs.
