RENOVACO2 aims at developing atmospheric plasma technologies to induce chemical processes that are currently carried out through catalytic techniques (i.e., at high pressures and temperatures, using harmful and non-recyclable catalysts). Specifically, RENOVACO2 pursues the development of a Dielectric Barrier Discharge Reactor (DBD) to induce two processes of great environmental impact, such as the splitting of the CO2 molecule and its revalorization in high-valued products. RENOVACO2 proposes, in a first stage, to develop the DBD technology through the design, construction, modelling, and commissioning of a disruptive new plasma reactor. In a second stage, it is proposed to build a second prototype reactor powered with renewable energy sources through the connection to a solar panel.
