Power-to-X (PtX) offers a transformative solution to the intermittency issues associated with the growing integration of renewable energy in our future energy systems. It is an umbrella terms used to represent all the pathways for energy storage, conversion, and reconversion into various energy vectors. The focus of our analysis, however, is on chemical conversion and particularly carbon dioxide utilization pathways. This study is divided into two main parts, the central aim of the first part is to perform literature research to consolidate the knowledge of PtX processes, particularly for carbon dioxide utilization through chemical conversion pathways. During the first phase of the project, a high-level assessment of multiple CO2 valorization routes and molecules was performed based on the internal knowledge of Technip Energies (T.EN) and extensive literature research.
