IFP Energies nouvelles (IFPEN) is offering a PhD position in the field of power electronics for electric mobility. The research will focus on the development of a multifunctional traction inverter integrating additional functions (e.g., a DC/DC stage), providing new degrees of freedom compared to conventional two-level inverters.

Esters are highly sought-after compounds in the chemical, pharmaceutical, and cosmetic sectors. An innovative alternative to the esterification of the corresponding acids is the alkoxycarbonylation of olefins.

In the ever-growing context of electrification in the automotive sector, the lithium-ion battery is currently the market’s dominant technology. Nevertheless, the energy density of current batteries, and therefore the range of electric vehicles, remains low compared to that of internal combustion vehicles.

An increasing number of geothermal doublets operate fractured or heterogeneous deep reservoirs, where heat production is often combined with lithium extraction.

The global temperature difference between the pre-industrial era and the last ice age was 6°C. Given the +4°C projected by 2100 under current trends, the Paris Agreement leaves only one generation to deploy the 'Sobriety, Efficiency, Technology' triad. This applied research project focuses on the 'Technology' pillar.

La thèse proposée vise à étudier le cycle du carbone et son potentiel de séquestration dans sols à faibles teneurs en matière organique, et notamment dans les écosystèmes arides et semi-arides. Ces écosystèmes couvrent plus de 40% de la surface terrestre (Plaza et al.

Le stockage géologique de CO2 est souvent considéré comme une des stratégies d'atténuation d’émission de CO2 permettant de limiter le réchauffement climatique.

Large Eddy Simulation (LES) is increasingly being used for the design of new combustion systems, particularly decarbonized ones. In the case of premixed combustion, part of the flame wrinkling is not resolved on the LES grid and requires specific models.

Comme le réaffirme le rapport du GIEC "Impacts, Adaptation and Vulnerability" (GIEC, 2022), le captage et le stockage du CO2 (CSC) joueront un rôle clé dans la réduction des émissions nettes totales de carbone et donc dans l’atténuation du changement climatique mondial.

Plastics are used in various domains and their production is constantly increasing, which consequently leads to an increase in plastic wastes. The origin of aged plastics is wide, used additives even wider, with high dilution level, which drastically complicate recycling process.

With the emergence of new numerical schemes based on general meshes, new possibilities arise for meshing complex geological environments and thus tackling new challenges for the energy transition, namely CO2 storage and deep geothermal energy.

This project is part of the European ERC Synergy project Karst ( https://erc-karst.eu/ ), which aims to develop a predictive flow model for an entire karst network. We will simulate water flows, possibly marked with tracers, in networks comprising millions of nodes.
