  Project summary

Project name:

Cost-effective CO2 conversion into chemicals via combination of Capture and Electrochemical and Biochemical Conversion 

Project acronym: CELBICON 
Project duration: 04.2016 - 04.2019 
Financial support by: European Commission ( 
The conversion of CO2 into valuable chemicals or fuels by the use of renewable hydrogen will become a strategic goal in the next decades. It will entail not only the reduction of greenhouse gas emissions, but also the generation of renew­able compounds to be used instead of fossil ones. In this context, the EU-funnded project CELBICON (Cost-effective CO2 conversion into chemicals via combination of Capture, ELectrochemical and BIochemical CONversion technologies) aims at the development of new CO2-to chemicals technologies capable of operating at small scale with high efficiency as especially most of the renewable energy sources are decentralized.


The CELBICON- Process, as shown in the figure above, includes the Capture of atmospheric CO2, its conversion into synthesis gas in an Electro-catalytic reactor along with electricity and the subsequent Bio-technological conversion followed by a downstream processing into the final product (for example isoprene or bioplastics)

The part of KIT in the CELBICON project is the realization an energy efficient supply of the feedstock of the electro-catalytic reactor, which consists of a water/CO2 solution at elevated temperature and pressure. As the energy required for the dissolution of CO2 in water is dominated by the work needed to compress the gaseous CO2, a new method of compressing and dissolving simultaneously will be investigated by KIT on the grounds of recent developments.
