Lithium-ion batteries, although highly efficient, can pose risks not only under abusive conditions but also within normal conditions of use set by the manufacturer. The risks are not limited to everyday use, and also concern the industrial sector (storage, construction, reconditioning, waste treatment, recycling).

Global textile production has almost tripled since the 1970’s while manufacturers switched to synthetic fibres which now comprise 60-70% of all textiles. The end‑of‑life management of polyester, polyamide, polyurethane and their blends remains sub‑optimal at best.

Detecting gaseous emissions from either industrial storage sites or natural environments is a major challenge when it comes to controlling harmful emissions and greenhouse gases.

Direct air capture of CO₂ (DAC) is an emerging technology whose industrial deployment presents major challenges, including the processing of very large volumes of air, a substantial land footprint, significant resource consumption, and, consequently, local social acceptability.

One of the biggest unresolved challenges in offshore wind farm maintenance is the real-time prediction of wave-induced motions and forces, enabling repair vessels to approach turbines safely.

In order to reduce the environmental impact of transport and the chemical industry, IFPEN is investing in biorefineries, biofuels and bio-based chemistry. Among the targets being explored, fumaric acid has the potential to become a platform molecule, providing access to various bio-based molecules.

This PhD subject aims to develop a thermodynamically consistent model for thermo-hydro-mechanical-chemical (THMC) coupling in a porous medium subjected to multiphase flows.

This PhD position is part of the RAISE Franco-German research program funded by ANR (the French National Research Agency) and led by IFP Energies nouvelles (IFPEN) and TU Dresden.

The textile industry, responsible for 10% of global greenhouse gas emissions and 20% of water pollution, faces a major environmental challenge. With less than 10% of textile waste being recycled, and an insignificant share for chemical recycling (<1%), it is urgent to develop sustainable alternatives.

Lithium-ion batteries are essential for electric vehicles and stationary energy storage and play a pivotal role in the energy and ecological transition. These materials, which include critical and strategic metals such as lithium, nickel, cobalt, and copper, are in high demand, with supply chains heavily reliant on imports.

With the development of underground hydrogen storage, it is becoming increasingly important to anticipate how microbial communities will evolve and interact with injected H₂. This PhD project aims to develop a mechanistic model of microbial competition in hydrogen-rich subsurface environments.
