REMUS

Recovery of Metro Braking Energy for a Sustainable University

REMUS is a joint project between the European Metropolis of Lille (MEL) and L2EP, within the framework of the CUMIN demonstrator program at the University of Lille. The objective is to study various innovative solutions for improving the energy efficiency of the rail transport system of MEL. More specifically, the "Cité Scientifique" campus of the University of Lille is served by 2 metro stations, with nearby parking lots and a bus hub. This configuration would make efficient use of the metro's braking energy to power and meet the growing energy demand of nearby electric vehicle charging stations (including electric buses), thus contributing to the development of a campus based on e-mobility.

The REMUS project comprises two interconnected parts:

  • The development of specific energy simulation tools to assess energy flows in the rail system, integrating potential energy-saving technologies (energy storage systems, reversible traction substations, EV charging stations, etc.).
  • The development of a reduced-scale hardware-in-the-loop experimental platform, enabling simulation models to be validated and new innovative concepts to be tested experimentally before being integrated into the real system.

The REMUS project focuses on these two aspects, working to improve the energy efficiency of the metro system and targeting significant reductions in energy consumption and greenhouse gas emissions. Consequently, the strategies and technologies developed and implemented as part of the REMUS project could serve as a model of sustainable mobility for other campuses and cities wishing to reduce their carbon footprint.
