It is indeed expected that when some energy storage is installed along the line or on-board tram, energy recovery during braking can be enhanced. In fact, even when no enough load is present to adsorb energy from trains that are braking, the storage system can adsorb it, and deliver it at a different time, when enough load is present.

Braking energy of trams can be recovered in storage systems. • High power lithium batteries and supercapacitors have been considered. • Storage systems can be installed on-board or along the supply network. • A
