Credit: Markus Giger. Rolling stock manufacturer Alstom has introduced its new-generation tram Citadis X05, which features the company''s SRS charging system and Citadis Ecopack energy storage system. The vehicle was commissioned to be used on the newly inaugurated Cadam-Magnan section of the tramway line 2 for France''s Métropole Nice
The average construction cost of conventional tramways is 20 –23.5 M€/km (20 M€/km in Africa, 22.5 M€/km in Europe, 23.5 M€/km in North America). The construction cost of tramways with ground-level power supply system is about 20% higher than that of conventional tramways. The cost of each tram varies between 2.5 and 3.5 M€.
A tram consumes high energy during acceleration but, low energy thereafter. • Supercapacitors can be charged fast but, they have low energy density. •
The trams also feature on-board energy storage to reduce power use and network costs. The first G Class trams are scheduled to begin testing on the network from 2025, before taking passengers on Routes 57, 59 and 82 in Melbourne''s west.
This pilot project''s energy storage unit offers a capacity of approximately 500 kWh and is made up of around 20 battery systems which were previously used to cover thousands of miles in the
In order to design a well-performing hybrid storage system for trams, optimization of energy management strategy (EMS) and sizing is crucial.

Energy storage systems (ESSs) are enabling technologies for well-established and new applications such as power peak shaving, electric vehicles, integration of renewable energies, etc.
energy storage system is a good example for all catenary free tram application. 2 Main Technical Parameters of Vehicles The basic configuration of 100% low floor trams is five-car module; the whole train has two motor bogies and one trailer bogie. The vehicle
The focus is on two parts: (a) trams running on hydrogen in parallel with onboard batteries with energy-saving control techniques, (b) potential renewable energy sources to meet the demand power.
At present, energy storage trams have been successively deployed in commercial operations in China, Spain, and Germany, such as Guangzhou Haizhu, Jiangsu Huaian, Shenzhen Longhua, Wuhan Dahanyang
Trams with energy storage are popular for their energy efficiency and reduced operational risk. An effective energy management strategy is optimized to enable a reasonable distribution of demand power among the storage elements, efficient use of energy as well as enhance the service life of the hybrid energy storage system (HESS).
Compared with the traditional overhead catenary-powered trams, the energy storage tram has the following advantages: (1) more than 85% braking energy recovery rate and low operational energy
This document discusses energy storage devices in railway systems. It begins by describing how moving and changing train loads can cause voltage regulation problems on electrical railway networks. It then discusses how regenerative braking and increasing the number of substations have helped address these issues but have their own limitations.
In July 2021 China announced plans to install over 30 GW of energy storage by 2025 (excluding pumped-storage hydropower), a more than three-fold increase on its installed capacity as of 2022. The United States'' Inflation Reduction Act, passed in August 2022, includes an investment tax credit for sta nd-alone storage, which is expected to boost
Energy storage equipment costs Energy is stored in a 120-kWh Li-ion battery pack, which costs 1500–1800 US$/kWh [35]. Choosing the typical value of 1600 US$/kWh [36] for calculation, the total battery pack costs 192,000 US$. Vehicle costs
FCs require regular refueling with hydrogen, while the energy storage oriented auxiliary power units need to be recharged to maintain their storage capacity. By integrating PV panels into the refueling and recharging infrastructure of FC trams, it is possible to further improve the sustainability and reduce the reliance on non-renewable
In the hybrid energy storage system of electric vehicles, the main objective is to guarantee that the dc-bus voltage tracks the desired set point quickly and accurately. However, it is typically difficult for existing methods to provide both short settling time and small overshoot, which results in significant dc-bus voltage fluctuations. To address this
A supercapacitor and accelerating contact line hybrid tram system is proposed. •. A tram consumes high energy during acceleration but, low energy thereafter. •. Supercapacitors can be charged fast but, they have low energy density. •. During acceleration, a tram draws power from accelerating contact line. •.
