472626 Electrochemical Carbon Dioxide Reduction As an Alternative Source of Fuels and Chemicals
The key cost-drivers of ECO2R are the energy efficiency, product selectivity, and current density. Based on these metrics, we have developed a model for the cost of ECO2R-derived compounds. We will use the model to compare the cost of ECO2R derived compounds to fuels and chemicals derived from traditional sources. In doing so, we will identify the technical barriers that need to be overcome to reduce the cost, including enhanced electrocatalysis [1-3] and achieving high current densities needed for a cost-competitive process because of limited carbon dioxide solubility.
Opus 12 has also developed a prototype ECO2R reactor. The Opus 12’s prototype contains improved catalysts and a reactor design with high energy efficiency, high product selectivity and high current densities. We will present our technical progress in terms of these key performance metrics. Using these metrics, we can estimate the current cost of ECO2R and present a roadmap of improvements needed to further reduce costs to compete with traditional chemicals and fuels derived from fossil resources.
