The use of biomass/biomass residues as feedstocks for bioenergy and biofuel processes is of rising interest for climate change mitigation. Thermochemical conversion of biomass in fluidized bed reactors, through pyrolysis, gasification, and combustion, requires efficient feedstock penetration and mixing through reliable feed injection systems.

Plastics recycling through chemical recycling routes has attracted a great deal of interest in recent years, to cope with complex plastics streams not handled by classical industrial mechanical recycling routes.

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.

With the announced drastic reduction of the amount of fossil energy resources in the European energy mix, it is important to define viable alternatives to petrochemicals. The transformation of lignocellulosic biomass and the various synthesis processes make it possible to provide a wide variety of families of compounds with high added value.

Under the European Green Deal, the demand for advanced secondary batteries is a pressing challenge. Critical for the impending energy transition, these batteries are instrumental for advancing the electric vehicle market, a linchpin for EU industrial and economic expansions.

Understanding the hydro-sedimentary dynamics at the watershed scale in response to daily or multi-year forcing is a key challenge in assessing the impact of climate change on water resources.

Pour répondre aux défis du domaine de l’énergie, IFPEN propose aujourd’hui un procédé qui permet de produire de l’éthanol à partir de biomasse lignocellulosique.

INRIA and IFP Energies nouvelles, leading French research laboratories, are seeking a talented and motivated master's student to join their team for a PhD position. As numerical simulation plays a pivotal role in our research and industrial applications, optimizing the performance of our parallel simulators is crucial.

Electric cars contribute to the de-carbonization of the transport sector and their massive deployment is foreseen. In this context, the battery industry strives for ever improved technologies, both in terms of performance and safety.

It is now established that molecular hydrogen (H2) exists naturally on the planet in the form of diffuse or continuous emanations. However, many questions remain unanswered as to its origin, formation mechanisms and real potential for exploitation.

The numerical discretization of physical models representing evolutionary problems in many fields leads to nonlinear algebraic systems of very large dimensions. The process of solving these systems, which must be carried out robustly and rapidly at each time-step in order to increase software efficiency, comes up against a number of obstacles.

As part IFPEN activities on Energy Transition Sustainable Development, a doctoral thesis is proposed in the Electrochemistry and Materials Department at IFP Energies Nouvelles Solaize, 10 km from Lyon, in collaboration with the company APERAM (CIFRE funding).
