ABSTRACT:
Methane is produced by dissolving mineral carbonate in water to produce dissolved carbon dioxide which is converted to methane by anaerobic methanogenic bacteria in the presence of hydrogen gas supplied to the water. Preferably, the mineral carbonate is in the form of a bed of particulate mineral carbonate with the bacteria attached thereto. The bed is submersed in the water in a closed vessel and a flow of hydrogen gas is passed through the vessel.
