CELBICON – Cost-effective carbon dioxide conversion into chemicals

Combination of Capture, ELectrochemical and Biochemical CONversion technologies

CELBICON aims at the development new CO2-to-chemicals technologies by conjugating CO2 capture, electrochemical CO2 conversion into intermediates and fermentation of these intermediates into value added chemicals. Each subsystem entered the CELBICON project as a stand-alone technology at a certain technology readiness level. During the CELBICON project these technologies will be further developed and integrated into a single, decentralized, cost-effective and robust technology platform operated at TRL5. The key criteria for the underlying process development are:

  • Achievement of high product yields at moderate operating temperatures and low maintenance costs.
  • Integration of several material- and energy recycle loops to enhance the overall efficiency, thereby increasing the opportunities for a faster market penetration of the technology platform.

Over a 42 months project duration 12 partners from 7 countries will put their key enabling technology developments together in order to achieve unprecedented yield and efficiency along the following two process line prototypes:

  • High pressure process line: Tailored to the production of a polyhydroxyalkanoate (PHA) bioplastic and pressurized methane via intermediate electrochemical generation of pressurized syngas followed by specific fermentation steps. Furoic acid production is envisaged for the valorisation of the anodic reaction.
  • Low pressure process line: Focused on the production of value added chemicals such as isoprene, lactic acid and monoterpenoids via electrocatalytic reduction of CO2 to water-soluble C1 intermediates followed by fermentation. For the anodic reaction the on-site treatment of the wastewater by advanced oxidation processes is envisaged.

Three integrated test rigs will be assembled and operated at TRL5 to prove the achievement of the techno-economic targets.
