The benefits of speed regulation in urban areas are demonstrated in terms of air quality, fuel consumption and traffic flow

Urban speed limits are one of the solutions available to big cities to improve traffic flow, to raise air quality, to rein in noise and to improve road safety. The prospect of additional benefits by adapting this limitation in real time, depending on traffic density, led an IFPEN team to evaluate this approach as part of a thesis work.

Electric motor: oil cooling is more difficult

The thermal management of electric motors is an essential element in competitive low-carbon mobility, since more efficient cooling not only increases motor performance density (power or torque by mass), but also improves operational reliability by preventing deterioration phenomena (such as demagnetization)...

Power electronics at the heart of electric mobility challenges

In the case of electrified vehicles, whether battery-powered (electric or hybrid) or powered by fuel cells (FC), power electronics (PE) converters play a major role, as they are used for a variety of functions. For example, they are used to drive electric motors, manage on-board energy or control traction battery recharging...

Road transport emissions: integrated research for air quality!

According to the WHO, 7 million premature deaths worldwide each year are linked to poor air quality, a problem to which road transport makes a significant contribution. Thanks to regulatory and technological developments, as well as the renewal of the vehicle fleet, emissions from this sector have certainly been falling in recent years. However, it remains a major contributor to the deterioration of air quality...

SC7 - Variable speed limits: for more eco-friendly urban traffic management

Driven by environmental and energy frugality challenges, there is growing interest in vehicle fuel efficiency and a reduction in the impact of mobility. While the promotion of alternative transport modes to cars remains the principal lever for change, much can still be done in terms of road traffic management. An IFPEN team worked on this subject as part of a thesis in collaboration with Gipsa-lab...

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...

Battery behavior: a complexity best taken into account by modeling

For around fifteen years now, IFPEN has been focusing on modeling conventional batteries to represent their nominal operation (electric and thermal behavior during normal operation), throughout their lifetime (...) and in the event of thermal runaway (failure, improper use)...

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...

Identification of reforming active phase catalytic descriptors

​​​​​​​The vast majority of oil refineries are equipped with a catalytic reforming unit that fulfils three main functions: production of high-octane oil cuts for gasoline production (known as reformates), production of aromatic-rich cuts containing fewer than 10 carbon atoms, used in the chemicals industry, and generation of dihydrogen, primarily used in hydrotreatment and hydrocracking units...
