Bioconversion of carbon dioxide to methane using hydrogen and hydrogenotrophic methanogens

Popis výsledku v původním jazyce

Biogas produced from organic wastes contains energetically usable methane and unavoidable amount of carbon dioxide. The biological conversion of this CO2 to methane is well known reaction without the demand of high pressure and temperature and is carried out by hydrogenotrophic methanogens. Reducing equivalents to the biotransformation of carbon dioxide from biogas or other resources to biomethane can be supplied by external hydrogen. Discontinuous electricity production from wind and solar energy combined with fluctuating utilization cause serious storage problems that can be solved by power-to-gas strategy representing the production of storable hydrogen via the electrolysis of water. Biomethanization of CO2 can take place directly in anaerobic digesters fed with organic substrates, in separate bioreactors or in hybride reactor which combines both methods. There are many studies with different bioreactors arrangements and a way of enrichment of hydrogenotrophic methanogens, but the system still has to be optimized for a higher efficiency. The aim of the paper is to gather and critically assess the state of a research and experience from laboratory, pilot and operational applications of carbon dioxide bioconversion and highlight further perspective fields of research.
