Tram energy storage dormitory

What is a battery powered 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.

Are there battery powered trams in Florence?

In Florence, battery powered trams have been tested since 2021. Fitted to trams on the existing Sirio fleet, the battery technology enables the trams to operate on a section of the line entirely under battery power, without the use of overhead infrastructure.

Should rail vehicles have onboard energy storage systems?

However, the last decade saw an increasing interest in rail vehicles with onboard energy storage systems (OESSs) for improved energy efficiency and potential catenary-free operation. These vehicles can minimize costs by reducing maintenance and installation requirements of the electrified infrastructure.

Does Hitachi Rail offer a battery-powered tram?

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.

How much energy does a hybrid storage system use?

The total weight of the hybrid storage system is 1646 kg, resulting in specific energy and power of 11.45 Wh/kg and 226 W/kg, respectively. The storage solution demonstrates effective energy savings and wireless operation capability up to 2.5 km.

Where are hydrogen trams being tested?

Testing of trial hydrogen trams has started recently in the cities of Saint Petersburg, Russia, and San Bernardino, California .
