The Bio-P2G-program (Bio-Power to Gas) at the Hanze University of Applied
Sciences evaluates the technologic feasibility of the biological reduction of carbon
dioxide with hydrogen to methane (biomethanation: 1 CO2 + 4 H2 -> CH4 + 2 H2O)
Chemically, this process is known as the Sabatier reaction, but within anaerobic
digestion the biological methanation is catalyzed by a specific group of
microorganisms: the hydrogenotrophic methanogens.
