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.

Behavioral economics for studying perceptions of bioengineered products

The field of power electronics is currently undergoing a major revolution thanks to the emergence of wide bandgap (WBG) components, such as SiC and GaN. These technologies pave the way for power converters capable of operating at unprecedented voltages, frequencies, and temperatures, while significantly increasing power density.

Explainability of numerical models has become a major challenge for engineers. In this context, sensitivity analysis is a key tool: it makes it possible to identify and rank the most influential parameters on a model’s or system’s performance, thereby strengthening confidence in the results and supporting decision-making.

Do you want to contribute to the environmental transition and take on a major scientific challenge? This PhD project offers the opportunity to develop innovative solutions for a critical issue: the sustainable recycling of textiles and batteries.

Structural integrity is a major challenge for the reliability and durability of wind turbines. Operational Modal Analysis (OMA) is currently a reference method for characterizing the dynamic state of structures from vibration measurements, but it still relies mainly on networks of accelerometers, whose spatial coverage remains limited.

Recycling plastics is one of the main ways of combating the impact of human activity on the environment. To improve the circularity of these materials, IFPEN is working on industrial solutions involving the design and development of new plastic transformation processes for recycling.

IFP Energies Nouvelles offers an innovative PhD opportunity at the intersection of Artificial Intelligence (AI) and High-Performance Computing (HPC).

The global energy transition towards the electrification of transportation has triggered an unprecedented demand in battery production, leading to a critical need for the sustainable recovery of strategic metals such as lithium or cobalt.

Zeolites, characterized by their well-defined crystalline and nanoporous structures, are pivotal in transitioning from fossil fuels to renewable energy sources to produce fuels and chemicals.

The current industrial production of hydrogen peroxide (H2O2) relies predominantly on the anthraquinone process, a mature but energy-intensive, complex technology associated with significant CO2 emissions.
