Abstract
Valorization of CO2 and biomass waste streams via electrochemical conversions is a sustainable alternative for the production of fine chemicals and commodity chemicals. This topic has gained a lot of attention in the past decades and major research efforts have been put into it. Key advances has been achieved in the field of material development, where, novel catalysts have been synthesized, developed and have demonstrated to increase the efficiency and selectivity towards the targeted products. Relatively to the large number of studies focused on material development, limited studies are focused on process development, reactor optimization and product separation. Although material development is of paramount importance to achieve an adequate electrochemical reaction performance, it is only the first step needed in order to develop a competitive technology. Process development offers the possibility of enhancing the overall performance of the technology by looking not only at the reaction level, but finding engineering solutions to overcome critical limitations. Process development is essential in order to accelerate the technology towards its envisioned application and advance towards commercial realization. In this talk, we will present several optimization strategies (beyond material development) that helped increase the overall performance of several electrochemical conversion processes, as well as the economic profitability of the complete system.In addition, in order to advance the technology on the TRL scale and have a positive market potential, the technology needs to be evaluated in several aspects such as the scaling-up challenges, its cost competitiveness and its climate benefits. For this, it is crucial to consider the complete value chain, and evaluate not only the electrochemical reaction but also the upstream and the downstream processes. A complete system approach is paramount for the development of competitive technologies. In this talk we will also show several examples on different process intensification strategies and its benefits on the economic potential of them.
