Electrochemical CO2 Conversion

Detailed overview of innovation with sample startups and prominent university research


What it is

Electrochemical CO2 conversion is a promising technology that utilizes electricity to drive chemical reactions, transforming carbon dioxide (CO2) into valuable products like fuels, chemicals, and building materials. This process offers a sustainable pathway to address climate change by capturing and utilizing CO2 emissions while creating a more circular and resource-efficient economy.

Impact on climate action

Electrochemical CO2 Conversion innovatively transforms carbon dioxide into valuable products, reducing greenhouse gas emissions. By employing this technology on an industrial scale, it accelerates the transition to a low-carbon economy. Its potential lies in mitigating climate change by converting a pollutant into valuable resources, fostering sustainability and climate action.

Underlying
Technology

Electrochemical CO2 conversion relies on the principles of electrochemistry:

  • Electrolysis: Similar to water electrolysis, which splits water into hydrogen and oxygen, this process uses an electrochemical cell with electrodes immersed in an electrolyte solution.
  • CO2 Reduction Reaction: When an electrical current is passed through the cell, CO2 molecules at the cathode (negative electrode) undergo reduction, gaining electrons and transforming into various carbon-based products.
  • Product Selectivity: The type of product formed depends on the catalyst used at the cathode, the applied voltage, and the composition of the electrolyte.
