Optimised braking energy recovery in electric public transport systems

Summary

Braking energy recovery technologies are an opportunity to increase the energy efficiency in public transport systems like metro, light rail/tram or trolleybus networks and will be presented during this first webinar of the ELIPTIC project (link is external). Different technologies in this field are part of the work in the use cases of Pillar B “Innovative energy storage systems to increase operational efficiency” of the ELIPTIC project. After a short introduction into the work of the ELIPTIC project and the objectives and use cases related to the webinar’s topic, the presenters from the public transport companies STIB (Brussels, Belgium) and PKT (Gdynia, Poland) will show braking energy recovery technologies for metro (and how to transfer the approach to light rail) and trolleybus systems. They will explain their development background from the European projects Ticket to Kyoto (NWE Interreg) and CIVITAS-DYN@MO, and show experiences with their systems in operation as well as results in terms of increased operational efficiency through these systems. Furthermore, they will present how their current braking energy recovery approaches and technologies will be developed further in the ELIPTIC use cases.
