Integration of oxycombustion and microbial electrosynthesis for sustainable energy storage 2022 Access copy available to the general public Unrestricted Power-to-gas technology makes use of surplus electricity by its conversion and storage in the form of a gas. Currently power-to-gas schemes based on biological processes are of great interest. Microbial electrosynthesis (MES) cells are biological systems that produce biogas via microbial action and a supply of electrical energy. The OxyMES scheme proposed is a power-to-gas system that seeks to neutralize the CO2 emissions of a standard industrial process through the hybridization of oxy-fuel combustion and bioelectrochemical processes that produce CH4 (in cathode) and O2 (in anode). This oxygen is used for oxycombustion in an industrial C-fuel boiler. The energy balance analysis yielded a power-to-gas efficiency in the MES cell close to 51%, and the overall performance of the OxyMES integrated system was close to 60% for a cell with a Faradaic efficiency of 80%, CO2-to-CH4 conversion rate of 95%, and ¿Vcell = 1.63 V. With the proper sizing of the CO2, O2, and biogas process tank system, it is possible to achieve 100% autonomy, free from external feedstock supplies. © 2022 Elsevier Ltd info:eu-repo/grantAgreement/EC/FP7/268191/EU/Reliable and Efficient Combustion of Oxygen/Coal/Recycled Flue Gas Mixtures/RELCOM info:eu-repo/grantAgreement/ES/MCIN-AEI-FEDER/PID2020-115948RB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 10.4 2022 ENERGY & FUELS 17 / 119 = 0.143 2022 Q1 T1 THERMODYNAMICS 2 / 63 = 0.032 2022 Q1 T1 MECHANICS 3 / 137 = 0.022 2022 Q1 T1 2.514 2022 Energy Engineering and Power Technology 2022 Q1 Renewable Energy, Sustainability and the Environment 2022 Q1 Nuclear Energy and Engineering 2022 Q1 Fuel Technology 2022 Q1 19.1 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Morán, A.
