H2020 FETPROACT-EIC-07-2020 with subtopic “breakthrough zero-emissions energy storage and conversion technologies for carbon-neutrality” is been applied wıth PACultra project, which includes comparison of many different cold plasma processes, plasma environment optimised catalysts and O2 separation membrane. The main goal is to enable production of fuels in single reactor using CO2 and H2O.

PACultra aims to investigate, develop and validate a prominently more efficient breakthrough carbon neutral technology in lab scale, incorporating a carefully tailored catalytic cold plasma process, to enable  widespread production of zero-emission fuels from CO2 and H2O storing excess renewable energy in an ultra-flexible way.

As different targets (1) syngas, and (2) methanol/(direct)DME production will be investigated in specially tailored single catalytic cold plasma reactors, using CO2 from various different sources, to also evaluate the effect of impurities, and water, which can be considered as the most ubiquitous feedstock. Dielectric Barrier Discharge, water-cooled Dielectric Barrier Discharge, Glow Discharge, Gliding Arc Discharge, and Rotating Gliding Arc cold plasma systems will be compared, with many different configurations and setups.

Novel catalysts particularly optimised for the different cold plasma environments will be developed via ab inito modelling and employed together with several novel support materials. Also, an innovative O2 removal membrane will be used to prevent recombination of reactants.

The anticipated CO2 conversion is >90%, and the targeted energy efficiency of the process is 60%, which is indeed very ambitious considering the inert CO2 and H2O feedstock. This way, PACultra will pave the path for carbon neutrality with its efficient novel approach while utilising excess portion of renewable energy.
