Energy storage methods in railway systems

A. Fernández-Cardador A.P. Cucala A. Fernández Rodríguez M. Domínguez

April 2023 - March 2025

Funding entity Union Internationale des Chemins de Fer (UIC), ADIF, Infrabel, Network Rail, RFI

Participated by ADIF, Infrabel, Network Rail, RFI


The goal of the project is to provide a decision-making tool based on simulation, and guidance to assist infrastructure managers when planning to increase the energy efficiency of railway stations by using the energy regenerated in braking trains by means of Energy Storage Systems located in stations.
This goal of the project is decomposed into three specific objectives: (1) to study the latest and different technologies in energy storage that could be suitable for this application; (2) to develop a decision software tool based on simulation to analyse the best ESS solution for each station type, based on its consumption and traffic; (3) to develop an IRS (International Railway Solution) draft on the implementation of ESS technologies in railway stations to make them more sustainable.
