Project Description

Faraday Technology, Inc., in partnership with Massachusetts Institute of Technology (MIT), is developing an economical and scalable process for gas-phase reduction of carbon dioxide (CO2) to hydrocarbons via a novel microstructured copper electrocatalytic system combined with a state-of-the-art flow reactor. The research team is using FARADAYIC® ElectroDeposition (ED), a low-cost technique developed by Faraday Technology, to perform pulsed electrodeposition of nanostructured copper particles onto a gas diffusion layer substrate, forming a gas-diffusion electrode (GDE) that will be incorporated into an electroreactor. Catalysts deposited by ED provide increased current density and enhanced selectivity compared to conventional spray-coated catalysts. In Phase I, researchers will investigate the effects of FARADAYIC® process parameters on copper electrocatalyst microstructures and develop a bench-scale prototype of a CO2-to-hydrocarbons electroreactor. Faraday will construct a deposition apparatus for the fabrication of copper catalyst-coated GDEs. Electroanalytical testing will be performed on the electrocatalysts to evaluate their selectivity for hydrocarbons, such as ethylene, and the total current density they are able to support. MIT will fabricate and evaluate a flow reactor prototype that combines a state-of-the-art flow reactor design and the copper catalyst-coated GDE to provide preliminary data on the performance of the overall system. Preliminary techno-economic and scale-up analyses will be performed to provide high-level metrics for the potential industrial-scale viability of the process.

Project Benefits

The innovative and scalable electrocatalytic technology enables cost-effective conversion of captured CO2 to value-added hydrocarbons and mitigates carbon emissions.
