ECO2Fuel means „Large-scale low-temperature electrochemical CO2 conversion to sustainable liquid fuels” and is a EU project under Horizon2020 (Green Deal). It aims to design, manufacture, operate, and validate the worldwide first low-temperature 1MW direct, electrochemical CO2 conversion system to produce economic and sustainable liquid e-fuels. The projects’ goal is to build a low-carbon, climate resilient future.
