Projectdetails

Introduction

The electrochemical conversion of CO2 to chemical fuels is a promising technology for recycling CO2 and closing the carbon cycle. Among the different products of the electrochemical reduction of CO2, multicarbon (C2+) products are more desirable because of their high energy density and high market price.

Market Potential

Among them, ethylene is widely used for the production of raw materials and has a market price around 1000€/ton, which suggests a relatively low threshold towards profitability.

Challenges

The development of such a technology to convert CO2 to C2H4 is, however, limited by:

  • The lack of selectivity and efficient catalysts to drive the reaction.
  • CO2 mass transportation to the active sites, which limits the conversion rate.

Previous Work

During the course of our ERC-StG 2D-4-CO2 project, we have developed Cu-based electrocatalysts modified with aromatic functions, which demonstrated strongly improved selectivity for ethylene at industry-relevant current density of 300 mA cm-2.

Project Goals

The aim of the HIPCEO2 project is to apply the novel Cu-based catalyst developed in our group in a high-pressure membrane electrode assembly electrolyzer. Our specific goals are to:

  1. Realize a prototype with an electrode size of 100 cm².
  2. Verify stability for 1000 hours.
  3. Use the prototype as a demonstrator to reach out to potential end-users and future partners.
