The wide array of available technologies provides a range of options to suit specific applications within the railway domain. This review thoroughly describes the operational mechanisms and distinctive properties of energy storage technologies that can be integrated into railway systems.
This study has been funded by the International Union of Railways (UIC) in the “Methods of energy storage for railway systems" project (RESS/RSMES 2020/RSF/669). (Funding partners ADIF, INFRABEL, NETWORK RAIL, RFI, NS, SBB and SZCZ).
Energy storage systems help reduce railway energy consumption by utilising regenerative energy generatedfrom braking trains. With various energy storage technologies available, analysing their features is essential for finding the best applications.
Mechanical ESS comprises compressed air energy storage, pumped hydroelectric storage, gravity energy storage and flywheel energy storage (FESS) . Only the latter will be described for their applicability to RS. FESSs store rotational energy.
Without storage, you''d lose precious energy like rainwater running off parched soil. Modern lithium-ion solutions now achieve 92% round-trip efficiency, making them perfect partners for Brasilia''s solar
