The nova Institute and EnergieAgentur.NRW are coming together to host the 7th CO2 Conference in Cologne. The vision of using carbon dioxide as both a resource within a circular economy and as a source of energy is increasingly becoming a reality: with the help of renewables, it is possible to produce gaseous and liquid fuels (methane, petrol, diesel, kerosene) from CO2 using various technologies. The most recent technological breakthroughs will be presented at the conference by world leaders in their respective fields. The event targets companies and research institutions working on the development of methods for the production of new fuels for efficient engines.
