| Résumé | This study demonstrates a novel approach for combined energy carrier production and energy storage in a Microbial Electrosynthesis System (MES). Continuous production of high purity methane (CH₄) from carbon dioxide (CO₂) was achieved in a 0.65 L carbon felt - filled cathode compartment of a membraneless MES. CH₄ production reached 0.72 L d−¹ at an energy consumption of 26 Wh LCH4−¹. Owing to the membraneless design of the MES, pH control of the electrode compartments was not required, with the cathode compartment pH remaining below 8.5. Electrochemical characterization showed a progressive increase of the MES internal capacitance from 2.1 F to 3.2 F. Bioelectrochemical conversion of CO₂ to CH₄ can be used for long-term energy storage (power-to-gas conversion) combined with CO₂ sequestration, while the internal capacitance of electroactive biofilms can be exploited to develop bioelectrochemical supercapacitors for fast energy return to the electrical grid. |
