- 3. confidential 3 The Archaea Transform Every Molecule of CO2 into Molecule of CH4 Without Using Fossil Fuels The methane is synthesized in each cell of the biocatalyst. There are trillions of cells working to produce methane in the reactor. The biocatalyst is a single- celled microorganism that belongs to the domain of Archaea. The cells are self- replicating in the reactor, as such, the system can sustain itself. CO2 + 4 H2 CH4 + 2 H2O + Heat carbon hydrogen methane water dioxide 4 H2O + e- 4 H2 + 2 O2 water electricity hydrogen oxygen Electrolysis is the process that produces hydrogen. Renewable hydrogen is synthesized in the electrolyzer from water and renewable electricity. Methanation Electrolysis Carbon Dioxide
