  • SYSTEM AND METHOD TO RECYCLE THE WATER AND AMMONIA AND OPTIONALLY OTHER CELL MEDIA NUTRIENTS FOR A POWER-TO-GAS PLANT IN BIOLOGICAL METHANATION UTILIZING BIOCATALYST (METHANOGEN)
    Publication number: 20240254518
    Abstract: The present invention refers to a method to convert H2 and CO2 into methane by methanogenic microorganisms in a bioreactor in a continuous production process for methane enriched gas compositions, while recycling of at least one ammonia compound and/or recycling of electrons, wherein water (H2O) serves as the carrier for electrons. Metabolic water is removed to keep concentrations constant and purified for feeding to electrolyzer to generate hydrogen for supply to methanation reaction to reduce need for freshwater and ammonia to be supplied.
