The aim of this study is to take stock of the different technologies used for the chemical conversion of CO2 in order to have a better understanding of their development potential by 2030 and of the main actions to be implemented in France to foster their emergence. To do this, the study was broken down into two main areas of focus:
- The review and characterization of the main CO2 chemical conversion routes for the synthesis of basic chemical products, energy products and inert materials. This review includes a presentation of the main principles underpinning the studied routes, a preliminary assessment of their performances, advantages and drawbacks, a list of the main R&D projects underway, a focus on emblematic projects as well as a brief analysis of the markets for the main products produced.
- Based on these elements, three routes were selected from among the most promising by 2030 for an in-depth analysis. This second section consisted in modelling the processes in question in order to further assess their energy, environmental and economic performances, and then to compare these performances both between processes and against conventional petrochemical routes. Consequently, the modelling goals were not to build a tool to dimension the processes, nor to say whether a technology will be competitive by 2030, but rather to analyze in what conditions they could become competitive.
