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 these products, 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:

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

Progress Made

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

Project Aim

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.

Specific Goals

Our specific goals are to:

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