The project ”CO2EXIDE – CO2-based electrosynthesis of ethylene oxide” that is coordinated by Fraunhofer IGB commenced on January 1, 2018 within the scope of the public-private partnership SPIRE (Sustainable Process Industry through Resource and Energy Efficiency).
The Straubing branch BioCat is developing a combined electrochemical-chemical technology for the production of ethylene oxide from biobased CO2. The CO2EXIDE approach unites physicists, chemists, engineers and communication experts from five research institutions, two industrial enterprises and three SMEs in this project. Through their key technologies, they will make a contribution towards the development of an unprecedented process based on CO2, renewable energies and water, thus demonstrating that the chemistry sector can be synergetically combined with the energy sector.
One of the central steps is the development of a new type of electrolyzer that enables a simultaneous reaction on both anode and cathode, which is more efficient in terms of energy and resources. The produced ethylene and hydrogen peroxide will finally be fed into a chemical cascade reactor and converted into ethylene oxide and different polyethylene glycols.
