ICCDU 2019 was definitely „the place to be“ for anyone working on carbon dioxide utilization and the event everybody has been talking about. See for yourself what happened in Aachen:

Carbon dioxide utilization requires the cooperation of many disciplines – the CO2 emitting industries as well as chemists, biotechnologists, engineers and experts for sustainability and life cycle analysis. This is reflected in the variety of scientific topics at ICCU 2019:

But carbon dioxide utilization is not only a matter of science and technology. Policy frameworks and social acceptance are prerequisites for its implementation, and they were discussed in Aachen, too:

If you think science is hard to visualize, see some of the presentations given at ICCDU:

A scientific conference is about research and hard facts, but also about people – here are some of the participants and their impressions:

Scientists reflect what they are doing – CO2 is something everbody is confronted with in their daily life:

And when we say, „everybody is talking about“ carbon dioxide utiliziation, we mean everybody!

Interview with Michele Aresta, Initiator of ICCDU and Member of the International Committee

This year’s ICCDU is the 17th edition of the event. What were your expectations when you started this series?
ICCDU was started after two Summer Schools funded by NATO on “CO2 as Carbon Source, 1986” and “Reaction Mechanisms in Enzymatic and Model carboxylation and reduction reactions based on CO2, 1989”.  The ICCDU Series was started for being the international forum where the scientific community working on CO2 conversion could meet. And this has been ICCDU since its start.

How would you describe the first ICCDU – was this more an academic discussion, or did you already envision concrete applications?
Surprisingly, in the 1980s there were already practical applications in the field of polymers from CO2 (Al-based catalysts) which went on stream. The scientific discussions already covered other themes such as CO2 reduction, photocatalysis, synthesis of fine chemicals, polymers such as polyurethanes and polycarbonates and so on. What people do today was well known in the 1980s. The interest in CO2 chemistry was at that time boosted by the“oil crisis” (1973, 2000s).  Climate change was not yet a serious issue. The low cost of oil has decreased the interest in CO2 conversion in the 2000-2010s. Now the push comes from climate change, a completely different motivation.
The scheme below was developed in 1987: it presents the vision I had about CCU 30 years ago:


 An Integrated approach to CO2 Utilization, M. Aresta, NATO ASI Series 1989.

The routes to go were very clear to me at that time! We are running now along those paths.

How has CCU (not the conference, but the technology) evolved since the first ICCDU? What expectations were met, what not? And did unexpected develpoments occur?
As I wrote in a paper published in JCOU in 2013 “The changing paradigm in CO2 conversion”, the availability of cheap PV-H2 makes possible today the exploitation of CO2 reduction to energy products, that did not make sense in a fossil-C based energy frame as it was in the 1980s. And this is a big step towards “circular economy of C”.

What is special about ICCDU compared to other events on the topic of CCS and CCU?
ICCDU is a scientific forum and gathers scientists from usually 35+ countries. In 2015 we had over 40 countries present. It is a global conference that has since a few years opened up to policy makers and industrialists: this is a must these days.

From your personal point of view, what are you looking forward to most at this year’s ICCDU?
In future years ICCDU will be more and more inclusive and will sustain the development of new science and technology in the direction of implementing a circular C-economy by integrating CO2 conversion, biotechnologies, and biomass utilization. Integration of biotechnologies, catalysis, photocatalysis is essential for CCU. Synthetic photochemistry is a key step. Integration with nature is essential. Learning from nature is our future.

What will, from your personal point of view, be the „next big thing“ in CCU?
Direct co-processing of water and CO2 for developing an “Economy based on CO2 and water”! This is the title of my most recent book published with Springer and this is my vision since ever.
CCU is cycling Carbon. CO2 is renewable carbon: one can cycle it again and again as Nature does. This is the basis of bioeceonomy: CCU is integrated with the Bioeconomy concept. We should not make the mistake of keeping biomass utilization and CCU apart! They must be integrated.

Join ICCDU 2019 in Aachen and discuss the opportunities and applications of carbon capture and utilization with experts from research and industry from all over the world!
