The Bio-P2G-program (Bio-Power to Gas) at the Hanze University of AppliedSciences evaluates the technologic feasibility of the biological reduction of carbondioxide with hydrogen to methane (biomethanation: 1 CO2 + 4 H2 -> CH4 + 2 H2O)Chemically, this process is known as the Sabatier reaction, but within anaerobicdigestion the biological methanation is catalyzed by a specific group ofmicroorganisms: the hydrogenotrophic methanogens.
Excess of renewable electricity from wind turbines or solar panels is used for electrolysis of water. To store this renewable energy as methane, the hydrogen is fed to an anaerobic digester to stimulate biological methanation by hydrogenotrophic methanogens. This workpackage focusses on the best ways for hydrogen delivery and the community changes in a biomethanation reactor as a result of hydrogen supply.
