Karst aquifers: IFPEN launches a research project in hydrogeology

On May 15, 2023, the kick-off meeting for the Karst project took place. This project aims to set up a multi-scale physical modeling framework for karst aquifers. This four-part project, which is backed by an ERC Synergy grant, will improve the modeling and prediction of the behavior of these systems during potentially dangerous extreme meteorological events (droughts and floods), as well as provide a deeper understanding of how they are formed.

Heavy trucks that run on hydrogen: a solution to reduce the carbon footprint of transport?

For transport segments where electrification is complex, such as heavy-duty vehicles (long-haul trucks and off-road vehicles ), hydrogen mobility appears to be a promising alternative to address the challenges of reducing the carbon footprint of the transport sector as a whole. While fuel cells have been the focus of a substantial amount of research in the context of low-carbon mobility, the IC engine using hydrogen as a fuel appears to be equally feasible as an alternative in order to significantly reduce CO2 and pollutant emissions.

Modeling wind turbine wake: a question of atmosphere!
In the wake zone located behind each wind turbine, wind velocity is reduced and turbulence increased. This results in a reduction in the lifespan of machines located downstream as well as a decrease in a windfarm’s overall electricity production. To limit these effects and help optimize the siting of turbines on windfarms, analytical wake models exist in the literature but they incorporate numerous simplifying hypotheses concerning wind turbines and their environment...

SC8 - “Massively” accelerated windfarm simulation

In the field of wind energy, Large Eddy Simulations (LES) are widely used to gain a better understanding of wind flow within wind farms. On a wind farm scale, they are also used to establish analytical wake models, and are useful for studying the interactions between individual wind turbines as well as with the atmospheric boundary layer (ABL)...

Wind farm optimization: in the wake of modeling advances
Wind energy accounts for an increasing share of the energy mix thank to the construction of wind farms designed to reduce investment and operating costs. However, within a farm, downstream wind turbines are exposed to the wakes of upstream rotors, leading to a reduction in their production and an increase in their fatigue stresses...

A better description of turbulent flows for hydrogen powertrains
Within the framework of a global policy to reduce the emissions produced by the transport sector - particularly road transport - IFPEN is focusing on a complementary option along with vehicle electrification: the use of hydrogen powertrains. However, the use of hydrogen in IC engines first requires a comprehensive understanding of different phenomena, associated, for example, with interactions between the fuel and air...
