the typical value of 1600 US$/kWh for calculation, the total battery pack costs 19 2,000 US$. than a conventional tram. For 8 trams on a 20 km rail line, the vehicle costs = 24.3 million US$ for a pantograph/catenary tram or contact-rail tram. ). contact-rail trams, respectively.
Hitachi Rail’s battery-powered tram technology offers the major benefit of requiring no electrified infrastructure. Our trams can operate on sections of routes with no overhead wires, such as historic city centres, like Florence, Italy, and offer range increase of up to 5km.
A sensitivity analysis is also performed. Results show that the life-cycle costs of trams are almost proportional to the rail-line length. The initial costs of a fuel-cell hybrid tram are less than a pantograph/catenary tram or contact rail tram.
The new technology is based on an onboard energy storage system (OBESS), with scalable battery capacity. It can be installed directly on the roof of existing trams - saving on costs, and visual impact – all while ensuring better environmental performance for a more sustainable society. In Florence, battery powered trams have been tested since 2021.
The life-cycle costs of trams are calculated for a 20 km rail line in Section 3.1. Each component of life- lengths. In Section 3.2, unit prices of fuel cell, battery and hydrogen are all allowed to vary for a fixed rail- line length; this enables a sensitivity analysis of the se parameters. Besides, life-cycle greenhouse emissions
Extending the work presented in , this study presents a battery and accelerating-contact line (BACL) hybrid tram system where a tram accelerates drawing power from a short contact line (‘ACL’), which can be in the form of a catenary, overhead busbar or third rail. The tram then cruises drawing power from traction battery, as shown in Fig. 2b.
