The direct electrocatalytic conversion of CO2 with Earth-abundant metals is a promising option that at present is at the lab research stage for both high-temperature (solid-oxide) and low-temperature (water electrolyte and PEM) devices. The application of this technology is currently hindered by the cost (e.g. the capital expenditure of electrolysers is > 500 € /kW). Both the cost of the technology itself and the current level of maturity of these technologies hinder their application. Electrochemical conversion with renewable power will be matured and scaled-up to produce fuels and commodity chemicals from CO2, H2O, O2, and N2.
