The University of Stuttgart has tested an optimised reactor that allows the splitting of CO2 in Direct current atmospheric pressure discharges at very high efficiency and conversion.

The use of plasma technologies in CCU is not new, but their ability to convert CO2 at atmospheric pressure has, up until now, remained low. This improved reactor facilitates the splitting of CO2 with up to 43% energy efficiency in the plasma at a high CO2 conversion of 27%. Furthermore, while the road to industrial exploitation of such technologies is usually paved with obstacles, the scaling up of this new reactor is feasible with minor challenges.

The research provides further insights into the wide range of potential applications of plasma technologies to convert CO2 into valuable products (CCU)
