SESSION 2, Materials by carboxylation
Saving energy is an easy way to reduce CO2 emissions, and not too painful, because you usually save money as well! But capturing CO2 is far more difficult technically, and, as of today, exceedingly expensive – we do not yet know of any business model that could justify the huge investments required. Moreover, whatever the capture technology and its associated costs, we also do not know what to do with the CO2 once it has been captured. Subterranean or submarine storage approaches are still under study and it is conceivable that they might not gain public acceptance. However, chemical applications could open new horizons. Although at first sight CO2 is a very stable molecule and its chemistry may look highly energy-consuming, I think it is time to look in more detail at such innovative approaches. In that respect, the « Large-volume CO2 recycling to Fuels and Materials » meeting at CPE Lyon should be a good occasion to help people progress towards smart solutions to the problem of how to use CO2 effectively.
