Title:Bubbles vs microbes: microbial electrolysis with and without bubbles
Research area and project description:The project aim is to study the upscaling potential of microbial electrosynthesis (water electrolysis in the presence of microbes which can convert the dissolved CO2 and Hydrogen into valuable chemicals) as a path towards large scale CO2 utilization. So far, high hydrogen concentration and bubble formation is avoided in such a process, which nevertheless, translates to small current densities and a slow production rate. The project aims to push this limit by studying the effect of hydrogen supersaturation and bubble formation.
The project involves three main activities: an experimental set-up with optical access will be developed to study the limits of hydrogen saturation and potential bubble formation in the presence of microbes. Moreover, interface-resolving CFD simulations will be used to study bubble formation and mass transfer. Furthermore, macro-scale CFD simulations will be used to optimize a bio electrochemical reactor.
The project is a collaboration between the Department of Mechanical & Production and Department of Biological & Chemical Engineering at AU under the umbrella of Novo Nordisk CO2 Research Center.
