The project will design, build-up, test and improve a lab-scale prototype electrolysis cell at TRL4 involving a selective electrocatalytic cathode for the hydrogen evolution reaction and an electrocatalytic anode capable of selectively oxidizing biomass-derived compounds. Aldose-type sugars and furanic compounds were selected as model biomass for the validation of the concept. These molecules will be selectively converted to value-added chemicals which can be valorised in various sustainable chemical processes such as the production of biopolymers. Furthermore, several emerging technologies rely on electrolysis assisted with an additional renewable source of energy (ultrasound, magnetic field) or coupled with the concept of electrochemical promotion of catalysis will be explored to further enhance the energy efficiency of the green hydrogen electrolytic production.
Main results
The ELOBIO consortium aims at advancing biomass electrolysis as a novel technological mean of green H2 production. ELOBIO will demonstrate that electrocatalytic oxidation of biomass-derived molecules offers the possibility to simultaneously reduce the energy cost and improve the chemical value of H2 production compared to the current water splitting technology. ELOBIO targets the development of low-temperature functional electrolysers capable of a large-scale production of H2 and value-added decarbonized chemicals, originating from the cellulosic biomass renewable exploitation.
