Achieving carbon neutrality targets by 2050 requires the development of significant CO2 geological storage capacities. As global capacity is not unlimited, carbonate saline aquifers, more reactive to CO2, will have to be considered as potential injection sites.

Bitumen emulsion techniques represent a major solution for decarbonizing road construction and lead to a significant reduction in the carbon footprint of roadworks.

The PhD aims to develop a methodological and operational framework for integrating geopolitical proximity and risk into prospective energy system modeling, with the objective of anticipating supply strategies in the context of increasing fragmentation. The work will unfold in three stages.

In a context where environmental and societal challenges related to plastic waste management are becoming increasingly urgent, the chemical recycling of plastic materials, such as the glycolysis of polyethylene terephthalate (PET), emerges as a complementary solution to traditional mechanical recycling.

Given the environmental urgency, the development of innovative technologies for capturing and storing CO2 is crucial. Traditional methods no longer meet current demands in terms of efficiency and capacity.

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.
