The 1st Electrochemical Conversion National Symposium

The future of Electrochemical Conversion

- Hydrogen and beyond -

Exploring the Future of Sustainable Chemicals and Fuels through Electrochemistry

The 1st National Symposium on Electrochemical Conversion took place on May 21st in the Netherlands. This event was a great success, below you find an overview and highlights of the day's activities.

The symposium focused on exploring the potential of electrochemistry to drive the development of sustainable chemicals and fuels. Experts from across the field gathered to discuss the latest advancements and future prospects in this important area of research and innovation.

Overall, the 1st National Symposium on Electrochemical Conversion was a success.

On behalf of the entire organizing committee, I would like to thank all of the speakers, poster presenters and attendees for making the ECCNS symposium a great success. We hope that you were inspired by all the great work on electrochemical conversions that is carried out by our community and made new connections that will help in future endeavours.

Personally, I was amazed by the high quality of presentations and posters by junior scientists, convincing me that we as a Dutch community can make a difference in solving the challenges related to employing electrochemical technologies in the near future to produce chemicals and fuels. I hope you thoroughly enjoyed your day at the ECCNS and hope to see you during the next edition of this symposium!

Summary of the Day by Hugo Pieter Iglesias van Montfort

Hugo attended various sessions throughout the day and provided a recap of the events.

Opening plenary session

“We’re trying to convert CO2 into products, but it’s very tough to compete with hydrogen. Our focus point should however not be the cost per ton of product, but the value per used energy unit. This means we can be less efficient and still obtain a higher value per used electron.

Our group studies salt formation and movement of ions in CO2 electrolyzers, so we understand what needs improvement. As it is right now, we still need 67% of Europe’s energy consumption to fulfil the world’s demand of only ethylene. Improving efficiency and stability of copper-based CO2 electrolysis is key in scaling this process."

Brian Seger from DTU opened the morning session explaining how his group studies CO2 electrolyzers, using X-rays!
One of the first breakout sessions in the morning was devoted to electrochemical engineering and study of CO2 electrolyzers, covering topics such as reactant distribution, activity detection and engineering CO2 capture devices.

Morning breakout sessions

(Bio) CO2 electrochemical conversions - electrolyser

“We need to use CO2 to close the carbon cycle but, as it is, we’re still 8 to 9 orders of magnitude away from the scale we need for that. In scaling these devices, we need to supress loss and crossover of CO2, otherwise the energy consumption gets so large that the electrolyzers don’t make sense. This is where, I think, engineering liquid-liquid electrolyzers still holds promise as a solution.” David Vermaas took us through his lab’s advances in CO2 electrolysis.

Afternoon plenary session

“In a sense, what everyone here today is trying to do is revolutionary. We’re trying to reverse one of the most famous reactions in the planet, the combustion of hydrocarbons, by just using CO2, water and electrons. And we need that, because the vast majority of our chemicals industry still has a fossil origin.

“In developing and studying these solutions, we need to keep a systems perspective in our work. For example, comparing our findings to traditional systems makes little sense. As of now, for example, CO2RR is 30x as intensive as direct-air capture of CO2. But, in our modelling we’ve seen already feasibility of integrated recycling streams. We’ve seen a lot of fancy numbers and performance metrics, but they’re irrelevant if we do not consider the impact on the wider value chain. A systems analysis helps us to find the best trade-offs in system design and engineering”.

André Bardow explained in the afternoon plenary how his group analyses sustainable production technologies from a holistic, system perspective. He also shared very cool insights on how we can achieve a major footprint reduction with readily available tech!
The afternoon sessions went from big to small, reviewing elementary process steps very close to the electrode, to integrating sustainable technologies like water electrolyzers to the ammonia production chains.

Afternoon breakout sessions

(Bio) CO2 electrochemical conversions - component

“As of now we’re developing electrolyzers mostly as black boxes. Using a variety of techniques, our group can keep an open perspective and analyse all the phenomena happening at a very small scale in our electrolyzers.

“For example, using in-situ Raman, we can follow the formation of intermediates on copper for the CO2 to hydrocarbons process. Similarly, using fluorescence and specially designed particles, we can probe the temperature of the interface while applying a current, which tells us more about real-life conditions.” Ward van der Stam took us through his group’s efforts at Utrecht University in the afternoon breakout sessions.

Poster awards

To close off the day, the poster awards sponsored by GroenvermogenNL were announced by Paulien Herder, chair of GroenvermogenNL. The third prize was a check for EUR 250, the second prize EUR 500 and the first prize a check for EUR 750.

After a very pressing evaluation period, the jury has come to the following decision:


1st price - Hugo-Pieter Iglesias van Montfort: Current distribution on flooding resistant electrodes for CO2 reduction

Very clear step by step conclusions that were made with self-explanatory images. An original concept potentially applicable to several fields with a variety of proof of concepts. The jury liked the descriptive titles that allow for limited reading to understand the primary point of each section. The graphic generated imagery of the work conveyed the geometries tested which allowed readers to understand the results much faster and clearer.


2nd price - Zhiyu Zhu: Operando NMR methods for studying electrochemical CO2 reduction

The use of a benchtop NMR for in-situ product detection is a very unique application with good preliminary results with time and potential resolution. Secondary measurements such as pH and formate add an additional research perspective. Overall the concept of benchtop NMR’s have potential to extend to other electrochemical applications, particularly as more complex reaction products maybe only detectable through liquid-phase analysis.


3rd price - Vojtech Konderla: Seawater CO2 capture using bipolar membrane electrodialysis

The approach is uniquely paired to existing applications of desalination such that the feedstock is more ion dense. The work then clearly recognises and discusses the challenges that this faces due to added scaling and its penalty on performance. In the end the results are put into a greater context. The judges liked the clear section headers and progress structure.

In the coming years the ECCNS symposium will continue

The Electrochemical Conversion National Symposium (ECCNS2024) brings those interested in green chemistry and green hydrogen together, in order to share the very latest insights in science and research. 

I am convinced by sharing knowledge as quickly and as openly as possible, the Netherlands can really accelerate the transition to a green society. This sharing takes place between scientists, but also between scientists and companies. 

Knowledge exchange in both directions provides mutual inspiration. GroenvermogenNL facilitates and accelerates this interaction: we bring companies in direct contact with scientists and we ensure that scientists can in turn learn from the findings in practice. 

In the coming years, we will continue to cooperate with ECCNS, this year in collaboration with TU Delft and in the future with at least one of the universities in the Netherlands. That way, we can effectively use the funds allocated to GroenvermogenNL by the National Growth Fund to make the Netherlands' innovation engine run even faster. With this innovation, we create new jobs, and a new sustainable economy. 

GroenvermogenNL is proud to be a sponsor and co-organiser of this symposium.
