A world without CO2?

Tags: CO2 capture, storage and recovery
Evaluation method:
Personal project with report and oral presentation
Course outline:

This track proposes to train Chemical Engineers in the field of energy involving CO2-free processes or the valorization of the latter. It requires multidisciplinary skills in chemistry, one of the characteristics of our students, because it requires knowledge in molecular chemistry, processes, catalysis, materials and physico-chemistry.
After a few elements of cellular energy, a brief description of photosynthesis from an energy and biochemical point of view will be described. The concept based on a biomimetic approach to artificial photosynthesis will be discussed. We will also see how, by drawing inspiration from microorganisms and using the energy capacities of bacteria, biopile makes it possible to recycle the components of organic waste when it is powered by hydrogen from biomass.
The case of biogas: A presentation of the diversity of policies that lead to a wide list of technologies used in Europe for biogas exploitation and purification will be made and a European mapping of CO2 emissions related to biogas sites will be established. The technological and phenomenological locks for the treatment of biogas impurities will be discussed. In the meantime, fuel cells will be presented quickly, emphasizing the nature of fuel gas and its specificities. The properties and exploitation of CO2 in high temperature devices will be presented, in particular CO2 electrolysis and CO2/H2O co-electrolysis.
Then the different capture processes, particularly by chemical absorption, will be detailed, with emphasis on the choice of solvent and the integration of the process into the plants based on the case study. One way to limit the release of industrial CO2 into the atmosphere is to store it in underground layers after it has been captured. We will discuss the different options considered.
Finally, the various battery technologies, their advances and prospects for transport and their life cycle will make it possible to consider a way of storing electricity in the context of sustainable development without CO2.

Learning objectives:

Describe, list and analyse the different possibilities for CO2 energy recovery
Explain the different storage routes with their advantages and disadvantages.
