TNO has initiated a multi-year, multi-million-euro research program focused on scaling up the electrochemical conversion of carbon dioxide to ethylene. This groundbreaking initiative aims to transform captured CO2 into a vital industrial feedstock using renewable electricity, marking a critical step in reducing the industry's reliance on fossil fuels.

Ethylene, a cornerstone of the chemical industry with an annual production of approximately 180 million tonnes, is currently produced through energy-intensive processes reliant on fossil feedstocks. Recognizing the urgent need for sustainable alternatives, TNO is championing Carbon Capture and Utilisation (CCU) technologies, specifically direct ethylene electrosynthesis, to pave the way for low-carbon materials and fuels.

While laboratory-scale experiments (TRL3) have demonstrated the potential of low-temperature CO2 electrolysis, the challenge lies in scaling up this technology to an industrial pilot (TRL6). TNO's program addresses this by collaborating with leading academic institutions like CEA (France), TU Delft (The Netherlands), and TU Valencia (Spain).

PhD researchers from these universities will work alongside TNO scientists and engineers, fostering a dynamic exchange of knowledge and expertise. Furthermore, the recently awarded RVO-MOOI project RESET-CO2 brings together SMEs and industrial partners such as VSParticle, Brusche Process Technology, e-ethylene, and Johnson Matthey, creating a robust ecosystem for technological advancement.

"By improving electrochemical technologies, we are working on the first industrial pilot for CO2-based ethylene," stated Michele Tedesco, Scientist and Project Manager, electrochemical engineering at TNO. This program aims to demonstrate the feasibility of large-scale electrochemical olefin production before 2030, paving the way for the construction of a first-of-its-kind industrial plant by 2040.

The successful implementation of this technology holds immense potential for decarbonizing the chemical industry and fostering a circular economy. By replacing fossil-based raw materials with sustainably produced ethylene, the industry can significantly reduce its carbon footprint and contribute to global climate goals. Moreover, the integration of large-scale offshore wind energy with electrochemical CO2 conversion offers a compelling pathway to sustainable and economically viable ethylene production.

"This project is a very strong example of our commitment to develop low-carbon, circular solutions for the chemical sector," emphasized Richard Braal, Division Director Industry within TNO’s Energy and Materials Transition Unit.

Senior Scientist Michele Tedesco further elaborated, "By advancing electrochemical conversion technologies, we are making concrete steps towards understanding the technology hurdles & steps that need to be taken to realise the first industrial pilot of CO2-based ethylene."

TNO's initiative signifies a crucial step towards a sustainable and circular chemical industry, demonstrating the power of collaborative research and innovation in addressing pressing environmental challenges.
