Deliverable 3.1: Summary report on the assessment of synthesis routes for catalysts preparation processes after atomistic simulations.

ECO2Fuel covers all the topics mentioned in the work program, which are described in the following by addressing each point separately and in detail. Develop and deploy highly innovative and recyclable catalytic material systems to facilitate the production of synthetic fuels from industrial flue gas CO2 emissions aiming at 50 % increase in the overall efficiency compared to the State-of-the-Art. Within the ECO2Fuel project, the activity is addressed to continue the development of the co-electrolysis carried out in the LOTER.CO2M project, a low temperature CO2 electrolysis system to convert CO2 from flue gas emissions into synthetic e-fuels. The general objective of ECO2Fuel, is to convert CO2 from flue gas without the need of hydrogen, electrochemically delivering carbonaceous fuels high conversion while the remaining electricity is converted to hydrogen. By breaking down the energy and conversion efficiency with respect to the products, the LOTER.CO2M systems achieved an overall efficiency of only 20%. ECO2Fuel sets the goal of reaching more than 85% faradaic conversion toward e-fuels and higher energy efficiency > 80%. This will translate into about 70% efficiency for producing carbonaceous fuels and foreseen to be achieved by a specific and goal-oriented optimization of materials and components, among which the catalytic systems play a crucial role.
